Moving the printer

The printer is heavy and should be lifted by two people. One person should stand at the front of the printer, and the other person should stand at the back of the printer. To lift the printer, grip the lift handles that are on the sides of the printer. Do not attempt to lift the printer by gripping any other part of the printer. If the bottom of the printer is attached to an optional accessory (such as a 500-sheet feeder, a 1,500-sheet feeder, or a storage cabinet), the accessory latches must be unlocked before moving the printer.

WARNING!

To prevent possible injury to yourself or damage to the printer, separate the printer from any currently installed optional accessories (for example, an optional feeder or a stapler/stacker) before lifting the printer.

Printing tasks

This section provides information about common printing tasks.

• Selecting which tray is used for printing
• Selecting the correct fuser mode
  • Stapling documents
• Loading trays
  • Understanding media output options
• Printing envelopes
• Printing on special media
• Printing on both sides of paper (optional duplexer)
• Canceling a print job
  • Using the printer driver
  • Using printer-driver features
  • Using job-storage features

Selecting which tray is used for printing

You can select how the printer pulls media from the trays. The following sections provide information about configuring the printer to pull media from specific trays.

Understanding tray order

Customizing tray 1 operation

Printing by type and size of media (locking trays)

Manually feeding media from tray 1

Understanding tray order

When the printer receives a print job, it selects the tray by trying to match the requested paper type and size with what has been loaded in the trays. Using an "autoselect" process, it searches all available trays for the paper that satisfies the request, starting with the bottom tray and ending with the top tray (tray 1). The printer begins printing the job as soon as it finds the correct type and size.

NOTE

The "autoselect" process occurs only if no specific tray is requested for the job. If a specific tray is requested, the job prints from the requested tray.

• If media is loaded in tray 1 and tray 1 is set TRAY 1 TYPE=ANY and TRAY 1 SIZE=ANY on the PAPER HANDLING menu, the printer will always pull media from tray 1 first. See Customizing tray 1 operation for more information.
• If the search fails, a message appears on the printer control-panel display requesting that you load the correct media type and size. You can load that media type and size, or you can override the request by selecting a different type and size at the printer control panel.
• If a tray runs out of media during a print job, the printer automatically switches to any tray that contains the same media type and size.

The autoselect process changes somewhat if you customize tray 1 operation (as explained in Customizing tray 1 operation) or if you set tray 1 for manual feed (as explained in Manually feeding media from tray 1).

Customizing tray 1 operation

The printer can be set to print from tray 1 if it is loaded, or to print only from tray 1 if the type of media that is loaded is specifically requested. See Paper Handling menu.

Setting Explanation
TRAY 1 TYPE=ANYTRAY 1 SIZE=ANY	The printer usually pulls media from tray 1 first unless it is empty or closed. If you do not keep media in tray 1 all the time, or if you use tray 1 only to manually feed media, keep the default setting of TRAY 1 TYPE=ANY and TRAY 1 SIZE=ANY on the Paper Handling menu.
TRAY 1 TYPE= or TRAY 1 SIZE= a type other than ANY	The printer treats tray 1 like the other trays. Instead of looking for media in tray 1 first, the printer pulls media from the tray that matches type and size settings that are selected in the software.In the printer driver, you can select media from any tray (including tray 1) by type, size, or source. To print by type and size of paper, see Printing by type and size of media (locking trays).

You can also determine whether the printer shows a prompt to ask if it can pull media from tray 1 if it cannot find the type and size that you requested in another tray. You can set the printer to always prompt you before pulling from tray 1 or only prompt you if tray 1 is empty. Set the USE REQUESTED TRAY setting on the System Setup submenu of the Configure Device menu.

Printing by type and size of media (locking trays)

Printing by type and size is a way to be sure that print jobs always print on the media that you want. You can configure the trays for the type, such as plain or letterhead, and size, such as letter or A4, that is loaded in them.

If you configure the trays this way and then select a certain type and size in the printer driver, the printer automatically selects the tray that is loaded with that type or size. You do not have to select a specific tray (selecting by source). Configuring the printer this way is especially helpful if the printer is shared, and more than one person loads or removes media frequently.

Some older model printers have a feature that "locks out" trays to prevent printing on the wrong media. Printing by type and size eliminates the need to lock trays. For more information about the types and sizes that each tray supports, see Supported sizes of print media.

NOTE

To print by type and size from tray 2, the optional trays, or the optional envelope feeder, you might have to to unload tray 1 and close it, or set TRAY 1 TYPE and TRAY 1 SIZE to types other than ANY on the PAPER HANDLING menu at the printer control panel. For more information, see Customizing tray 1 operation. Settings in a program or the printer driver override control-panel settings. (Program settings generally override printer-driver settings.)

To print by type and size of paper

1. Be sure to load the trays correctly. See Loading trays.)

2. At the printer control panel, open the PAPER HANDLING menu. Select the paper type for each tray. If you are unsure which type you are loading, such as bond or recycled, check the label on the media package.

3. Select the paper-size settings at the printer control panel.

4. Tray 1: Set the paper size on the PAPER HANDLING menu if the printer is set to TRAY 1 TYPE= a type other than ANY. If custom paper is loaded, also set the custom-paper size on the PAPER HANDLING menu. For more information, see Printing on small sizes, custom sizes, or heavy paper.

5. Tray 2 and optional 500-sheet trays: Standard paper sizes are automatically detected if the media is loaded correctly in the tray and the guides are adjusted correctly. See Loading trays for information about tray adjustments. If custom paper is loaded, set the knob in the tray to "Custom" and set the custom-paper size on the PAPER HANDLING menu. For more information, see Printing on small sizes, custom sizes, or heavy paper.
6. Optional 1,500-sheet tray: Standard paper sizes are automatically detected if the media is loaded in the tray correctly and the guides are adjusted correctly. See Loading trays for information about tray adjustments. Custom-size media is not supported.

7. Optional envelope feeder: Set the size on the PAPER HANDLING menu.

8. In the program or printer driver, select a type other than Auto Select.

The type and size settings can also be configured in the HP Web Jetadmin software for networked printers.

Manually feeding media from tray 1

The manual feed feature is another way of printing on special media from tray 1. Setting MANUAL FEED to ON either in the printer driver or at the printer control panel stops the printer after each job is sent, allowing you time to load special paper or other print media in tray 1. Press √ (SELECT button) to continue printing.

If tray 1 contains media when you send the print job, and the printer control panel has TRAY 1 TYPE=ANY and TRAY 1 SIZE=ANY as the default configuration for tray 1 operation, the printer will not stop and wait for media to be loaded. To have the printer wait, set TRAY 1 TYPE and TRAY 1 SIZE to types other than ANY on the PAPER HANDLING menu.

If the SIZE and TYPE are set to ANY, and MANUAL FEED PROMPT is set to UNLESS LOADED, then the media will be pulled from tray 1 without prompting. If MANUAL FEED PROMPT is set to ALWAYS, then the printer will prompt you to load media, even if tray 1 is set to TYPE=ANY and SIZE=ANY.

If you have selected MANUAL FEED=ON at the printer control panel, this setting will override the printer driver, and all print jobs that you send to the printer will request manually fed paper in tray 1 unless a specific tray has been selected in the printer driver. If this feature is to be used only occasionally, it is best to set MANUAL FEED=OFF at the printer control panel and to select the manual feed option in the printer driver on a job-by-job basis.

Selecting the correct fuser mode

The printer automatically adjusts the fuser mode based on the media type to which the tray is set. For example, heavy paper, such as card stock, might need a higher fuser-mode setting in order to make the toner adhere better to the page, but transparencies need the LOW fuser-mode setting to avoid damage to the printer. The default setting generally provides the best performance for most print-media types.

The fuser mode can be changed only if the media type has been set for the tray that you are using. (See Printing by type and size of media (locking trays).) After the media type has been set for the tray, then the fuser mode for that type can be changed on the CONFIGURE DEVICE menu in the PRINT QUALITY submenu at the printer control panel. (See Print Quality submenu.)

NOTE

Using a higher fuser mode, such as HIGH 1 or HIGH 2, improves the ability of the toner to adhere to paper, but it might cause other problems, such as excessive curl. The printer might print at a slower speed when the fuser mode is set to HIGH 1 or HIGH 2.

To reset the fuser modes to the default settings, open the CONFIGURE DEVICE menu at the printer control panel. On the PRINT QUALITY submenu, select FUSER MODES, and then select RESTORE MODES.

Stapling documents

The optional stapler/stacker can staple jobs of up to 15 sheets of 75 g/m^2 (20 lb) paper. The stapler can staple letter-size, A4-size, or legal-size paper.

• Paper weight can range from 60 to 120g / m^2 (16 to 32 lb). Heavier paper might have a stapling limit of fewer than 15 sheets.
• If the job consists of only one sheet, or if it consists of more than 15 sheets, the printer will print the job to the bin, but the printer will not staple the job.
• The stapler supports paper only. Do not try to staple other types of print media, such as transparencies or labels.

When you are ready to have the printer staple a document, select stapling in the software. You can usually select the stapler in your program or printer driver, although some options might be available only in the printer driver. Where and how you make selections depends on your program or printer driver.

If you cannot select the stapler in the program or printer driver, select the stapler at the printer control panel.

You might need to configure the printer driver to recognize the optional stapler/stacker. You need to set this setting only once. See the printer driver online Help for details.

The stapler accepts print jobs if it is out of staples, but it does not staple the pages. The printer driver can be configured to disable the staple option if the staple cartridge is empty.

To select the stapler in the software (Windows)

1. On the File menu, click Print, and then click Properties.
2. On the Output tab, click the drop-down list under Staple, and click One Staple Angled.

To select the stapler in the software (Mac)

1. On the File menu, click Print, and then select Finishing from the selectable print options.
2. In the Output Destination dialog box, select the Stapler option.
3. In the Stapler dialog box, select the stapler style.

To select the stapler at the control panel

1. Press M ENU to open the menus.
2. Use ▲ (UP button) or ▼(DOWN button) to scroll to CONFIGURE DEVICE, and then press √ (SELECT button).
3. Use ▲ (UP button) or ▼(DOWN button) to scroll to STAPLER/STACKER, and then press √ (SELECT button).
4. Use ▲ (UP button) or ▼(DOWN button) to scroll to ONE, and then press √ (SELECT button).

NOTE

Selecting the stapler at the printer control panel changes the default setting to STAPLE. It is possible that all print jobs will be stapled. However, settings that are changed in the printer driver override settings that are changed at the control panel.

Loading staples

Load staples if the printer control-panel display prompts you with a STAPLER LOW ON STAPLES message (the stapler has fewer than 70 staples left) or a STAPLER OUT OF STAPLES message (the stapler is empty). If the stapler runs out of staples, jobs continue to print to the stapler/stacker, but they are not stapled.

To load staples

1. On the right side of the stapler/stacker, turn the stapler unit toward the front of the printer until the unit clicks into the open position. Grasp the blue staple-cartridge handle and pull the cartridge out of the stapler unit.

Loading trays

This section describes how to load the standard and optional printer trays.

Loading tray 1

Tray 1 is a multipurpose tray that holds up to 100 sheets of paper, 50 transparencies or sheets of labels, 10 envelopes, or 20 index cards. The printer default is to pull media from tray 1 first, if it is loaded. To change this behavior, see Customizing tray 1 operation.

Tray 1 provides a convenient way to print on envelopes, transparencies, custom-size paper, or other types of media without having to unload the other trays. It can also be used just as a convenient additional tray. For supported media sizes, see Supported sizes of print media.

If an optional stapler/stacker is installed, the printer automatically rotates the printed images 180^ on all media sizes, even if the job is not stapled. If you are printing on paper that requires a specific orientation, such as letterhead, preprinted paper, prepunched paper, and paper with watermarks, make sure that the paper is loaded correctly in the tray. See Orientation of paper when a stapler is installed.

NOTE

The printer might print at a slower speed when using tray 1.

CAUTION

To avoid jams, do not load trays while the printer is printing. Do not fan the paper. Fanning can cause misfeeds.

To load tray 1

Loading an optional 1,500-sheet tray

The optional 1,500 sheet tray adjusts for letter, A4, and legal sizes. The printer automatically senses which size is loaded if the tray guides are properly adjusted.

If an optional stapler/stacker is installed, the printer automatically rotates the printed images 180^ on all paper sizes, even if the job is not stapled. If you are printing on media that requires a specific orientation, such as letterhead, preprinted media, prepunched media, and media with watermarks, make sure that the media is loaded correctly in the tray. (See Orientation of paper when a stapler is installed.)

Understanding media output options

The printer has three output locations: the top (standard) output bin, the rear output bin, and the optional stacker or stapler/stacker.

Printing to the top (standard) output bin

Printing to the rear output bin

Printing to the optional stacker or stapler/stacker

Orientation of paper when a stapler is installed

Printing to the top (standard) output bin

The top output bin collects paper face-down, in the correct order. The top output bin should be used for most print jobs, including transparencies. To use the top output bin, be sure that the rear output bin is closed. To avoid jams, do not open or close the rear output bin while the printer is printing.

Line drawing of a HP printer with control panel and paper airplane (no text or symbols)

Printing to the rear output bin

The printer always prints to the rear output bin if it is open. Media that is printed to this bin will exit face-up, with the last page on top (reverse order).

Printing from tray 1 to the rear output bin provides the straightest path. Opening the rear output bin might improve performance with the following items:

• Envelopes
• Labels
  • Small custom-size paper
• Postcards
  • Paper heavier than 120 g/m ^4 (32 lb)

To open the rear output bin, grasp the handle at the top of the bin. Pull the bin down, and slide out the extension.

Diagram of a computer tower internal structure showing internal components and a red arrow indicating a directional flow (no text or symbols present)

Opening the rear output bin makes the duplexer (if installed) and the top output bin unavailable. To avoid jams, do not open or close the rear output bin while the printer is printing.

Printing to the optional stacker or stapler/stacker

The optional stacker or optional stapler/stacker can hold up to 500 sheets of paper (20-lb paper). The stacker accepts standard and custom paper sizes. The stapler/stacker accepts standard and custom paper sizes, but only letter, legal, and A4 sizes can be stapled. Do not try to send other types of print media, such as labels or envelopes.

When a stapler/stacker is installed, the printer automatically rotates the printed images 180^ on all paper sizes, regardless of whether the job is stapled. Paper types that must be printed in the correct orientation, such as letterhead or prepunched paper, might need to be loaded in a different direction. See Orientation of paper when a stapler is installed.

To print to the optional stacker or optional stapler/stacker, select the option in the program, in the printer driver, or at the printer control panel.

Before you use the optional stacker or optional stapler/stacker, ensure that the printer driver is set to recognize it. You need to set this setting only once. See the printer driver online Help for details.

For more information about supported paper, see Supported sizes of print media. For more information about stapling, see Stapling documents.

Orientation of paper when a stapler is installed

When an optional stapler/stacker is installed, the printer automatically rotates the printed images 180^ on all paper sizes, even if the job is not stapled. If you are printing on paper that requires a specific orientation, such as letterhead, preprinted paper, prepunched paper, and paper with watermarks, make sure that the paper is loaded correctly in the tray. The correct orientation of the paper in the trays is shown below.

For duplex (two-sided) printing and stapling from tray 1, load the paper with the front side facing down and the top edge toward the printer. For duplex printing and stapling from all other trays, load the paper with the front side facing up and the top edge toward you.

Printing envelopes

You can print on envelopes from tray 1 or the optional envelope feeder. Tray 1 holds up to 10 envelopes and supports standard or custom sizes. The optional envelope feeder holds up to 75 envelopes and supports only standard envelope sizes.

For printing on any size of envelope, make sure to set the margins in your program at least 15 mm (0.6 inch) from the edge of the envelope.

Printing performance depends on the construction of the envelope. Always test a few sample envelopes before purchasing a large quantity. For envelope specifications, see Envelopes.

WARNING!

Never use envelopes that contain coated linings, exposed self-stick adhesives, or other synthetic materials. These items can emit noxious fumes.

CAUTION

Envelopes that contain -or- have clasps, snaps, windows, coated linings, exposed self-stick adhesives, or other synthetic materials can severely damage the printer. To avoid jamming and possible printer damage, never try to print on both sides of an envelope. Before you load envelopes, make that sure they are flat and are not damaged or stuck together. Do not use envelopes that have pressure-sensitive adhesive.

NOTE

The printer might print at a slower speed when printing envelopes.

Loading envelopes in tray 1

Many types of envelopes can be printed on from tray 1. Up to 10 can be stacked in the tray. See Envelopes for specifications.

To load envelopes in tray 1

1. Open tray 1, but do not pull out the extension. Most envelopes feed best without the extension. However, oversize envelopes might need the extension.

NOTE

Select the envelope size in one of these locations, trying them in this order: in the program, in the printer driver, or on the Paper Handling menu at the printer control panel. See Paper Handling menu.

Printing on special media

This section discusses printing on types of media that require special handling:

• Printing on labels
  • Printing on transparencies
  • Printing on letterhead, prepunched, or preprinted paper (single-sided)
  • Printing on paper that has a special finish
  • Printing on small sizes, custom sizes, or heavy paper
  • Setting custom paper sizes

Printing on labels

Use only labels that are recommended for use in laser printers. Make sure that labels meet the correct specifications. See Labels.

Diagram of a printer printing a grid-patterned sheet, showing mechanical components and a red arrow indicating the paper's direction (no text or symbols present)

Follow these guidelines when printing on labels:

• Print on a stack of up to 50 label sheets from tray 1 or a stack of up to 100 label sheets from other trays.
• Load labels in tray 1 with the front side facing up, and the top, short edge toward the printer. For other trays, load media with the front side facing down, and the top edge toward you.
  • Try opening the rear output bin to reduce curl and other problems.

Do not load or print on labels in the following ways:

CAUTION

Failure to follow these instructions can damage the printer.

• Do not load the trays to maximum capacity, because labels are heavier than paper.
• Do not use labels that are separating from the backing sheet, wrinkled, or damaged in any way.
• Do not use labels that have the backing sheet exposed. (Labels must cover the entire backing sheet, leaving no exposed spaces.)

• Do not feed a sheet of labels through the printer more than once. The adhesive backing is designed for only one pass through the printer.

• Do not print on both sides of labels.

• Do not print on sheets from which labels have been removed.

Printing on transparencies

Use only transparencies that are recommended for use in laser printers. For transparency specifications, see Transparencies.

- At the printer control panel, open the CONFIGURE DEVICE menu. On the PRINT QUALITY submenu, select FUSER MODES. Make sure that the fuser mode is set to TRANSPARENCY=LOW.

CAUTION

Failure to set the fuser mode to LOW can permanently damage the printer and fuser.

• In the printer driver, set the paper type to Transparency.
- At the printer control panel, open the PAPER HANDLING menu. Set the tray type to TRANSPARENCY for the tray that you are using.
- Load transparencies face up in tray 1 with the top toward the printer. Up to 50 transparencies can be loaded in tray 1. A stack of up to 100 transparencies can be printed from tray 2 and the optional trays (although stacking more than 50 at a time is not recommended). Because transparencies are heavier than paper, do not load trays to maximum capacity. Load them with the side to be printed on facing down, and the top, short edge toward you.
- To prevent transparencies from becoming too hot or from sticking together, use the top output bin and remove each transparency from the output bin before printing another.
• Print only on one side of a transparency.
- Place transparencies on a flat surface to cool after removing them from the printer.
- If two or more transparencies feed at the same time, try fanning the stack.
- Do not feed transparencies through the printer more than once.

Printing on letterhead, prepunched, or preprinted paper (single-sided)

When printing on letterhead, prepunched, or preprinted paper, it is important to orient the paper correctly. Follow the guidelines in this section for printing on one side only. For duplexing guidelines, see Printing on both sides of paper (optional duplexer).

NOTE

For more information about paper that has a special finish, such as laid or bond paper, see Printing on paper that has a special finish.

For tray 1, load the paper with the front side facing up, and the top, short edge toward the printer.

Diagram of a printer printing a stack of paper with a red arrow indicating the paper's edge (no text or symbols present)

For tray 2, optional 500-sheet trays, and the optional 1,500-sheet tray, load the paper with the front side facing down, and the top, short edge toward you.

Line drawing of a printer with an open lid and paper feed, showing internal components (no text or symbols)

NOTE

When Alternative Letterhead mode is enabled in the printer driver, and Letterhead or Preprinted is selected as the media type, you must orient the media for two-sided (duplex) printing.

Guidelines for printing on letterhead or preprinted forms

• Do not use letterhead paper that is printed with low-temperature inks, such as those used in some types of thermography.
  • Do not use raised or embossed letterhead.
• The printer uses heat and pressure to fuse toner to the paper. Make sure that any colored paper or preprinted forms use inks that are compatible with this fusing temperature (200°C or 392°F for .01 second).

Printing on paper that has a special finish

Some paper has a special finish, such as laid paper, bond paper, and cockled paper. These types of paper can cause issues in regard to toner adhesion and print quality. Follow these guidelines when printing on paper that has a special finish.

- At the printer control panel, open the CONFIGURE DEVICE menu. On the PRINT QUALITY submenu, select FUSER MODES, and then select the paper type that you are using (such as BOND). Set the fuser mode to HIGH 1 or HIGH 2. HIGH 2 provides better toner adhesion and optimal print quality for paper that has a highly textured finish. Open the PAPER HANDLING menu and set TRAY TYPE to the type of paper that you are using (such as BOND) to turn on the appropriate fuser mode.

NOTE

The printer might print at a slower speed when set at HIGH 1 or HIGH 2. Use the HIGH 1 and HIGH 2 settings only if you are experiencing toner-adhesion problems. The HIGH 1 and HIGH 2 settings might increase problems with curl and jams.

- Some makers of these types of paper are now coating one side of the paper to enhance toner adhesion and print quality. To take advantage of this feature, make sure to load the paper correctly. The side on which you can read the watermark correctly is the front side, or the side to be printed on.

For tray 1, load paper with the front side facing up, and the top, short edge toward the printer.

Diagram of a printer printing a stack of paper with a red arrow indicating the process (no text or symbols present)

For tray 2, optional 500-sheet trays, and the optional 1,500-sheet tray, load paper with the front side facing down, and the top, short edge toward you.

Line drawing of a printer with a paper feed into the main chamber, showing internal components and a red arrow indicating direction (no text or symbols)

Printing on small sizes, custom sizes, or heavy paper

Custom-size paper can be printed from tray 1, tray 2, or an optional 500-sheet tray.

NOTE

The printer might print at a slower speed when printing on small sizes, custom sizes, and heavy paper. For more information about paper that have a special finish, such as laid or bond paper, see Printing on paper that has a special finish.

Weight and sizes

See the following table for specifications when printing on custom or heavy paper. For more information, see Paper specifications.

Tray	Minimum size	Maximum size	Supported weights
Tray 1 76 x 127 mm	(3 x 5 inches)	216 x 356 mm(8.5 x 14 inches)	60 to 200 g/m ^2 (16 to 53 lb)
Tray 2 and optional 500-sheet tray	148 x 210 mm(5.8 x 8.2 inches)	216 x 356 mm(8.5 x 14 inches)	60 to 120 g/m ^2 (16 to 32 lb)

Guidelines for heavy paper

Follow these guidelines when printing on heavy paper:

• Paper heavier than 120g / m^2 (32 lb) should be printed only from tray 1. To reduce curl and other problems, print heavy paper from tray 1 to the rear output bin.
• To help prevent toner from rubbing off of the paper, some heavier paper types should be printed using a higher fuser mode. At the printer control panel, open the CONFIGURE DEVICE menu. On the PRINT QUALITY submenu, select FUSER MODES, and then select the media type that you want to modify. Select either HIGH 1 or HIGH 2 as the fuser mode. Using these modes helps prevent toner from rubbing off the page, but using them might slow the printer speed or create other problems, such as increased curl.

Guidelines for custom-size paper

Follow these guidelines when printing on any custom-size paper:

• Feed the paper short-edge first.
- In your program, set page margins at least 4.23 mm (0.17 inch) away from the edges.
- Set the custom size in the program, in the printer driver, or at the printer control panel. Make sure that you set the switch in the tray to Custom. See Setting custom paper sizes.

Additional guidelines for small or narrow paper

Follow these additional guidelines when printing on small or narrow paper:

• Do not attempt to print on paper smaller than 76 mm (3 inches) wide or 127 mm (5 inches) long.
• To reduce curl and other problems, print very small custom-size paper from tray 1 to the rear output bin.
• HP does not recommend printing large quantities of small or narrow paper. Printing large quantities of small or narrow paper can cause excessive wear on the print cartridge components that might result in toner leaking into the printer or might cause print-quality problems.

Setting custom paper sizes

When custom paper is loaded, size settings need to be selected in the program (the preferred method), in the printer driver, or at the printer control panel. To reduce curl and other problems, heavy paper and very small custom-size paper should be printed from tray 1 to the rear output bin.

Feed the paper into the printer short-edge first.

Printing on both sides of paper (optional duplexer)

The printer can automatically print on both sides of paper when an automatic duplexer is installed. This is called duplexing. The duplexer supports the following paper sizes: letter, legal, executive, A4, A5, and JIS B5.

NOTE

The automatic duplexer is included with the HP LaserJet 4250dtn, 4250dtnsl, 4350dtn, and 4350dtnsl printers.

For models that do not include an automatic duplexer, you can print on both sides manually. See To duplex manually. You can also order the duplexer as an accessory. See Ordering parts, accessories, and supplies.

The duplex slot cover that is located at the rear of the printer must be removed when the duplexer is installed. See the documentation that is included with the duplexer for installation instructions. When duplexing very complex pages, additional memory might be required. See Printer memory.

When the printer prints by using the duplexer, the page partially protrudes into the top output bin, and then reverses to print on the second side.

Guidelines for printing on both sides of paper

CAUTION

Do not print on both sides of labels, transparencies, envelopes, vellum, custom sizes, or paper heavier than 28 lb (105 g/m ^2 ) because jams or damage to the printer might occur.

Note the following guidelines:

• Before using the duplexer, ensure that the printer driver is set to recognize it. The procedure varies according to the operating system that you are using. For details, see Using the printer drivers. Look for the instructions in the column labeled "To change configuration settings."
• To print on both sides of paper, make the selection in your program or the printer driver. (See the printer driver online Help.)
• If you do not use the printer driver that came with the printer, you might need to change the duplex setting at the printer control panel, set DUPLEX=ON on the CONFIGURE DEVICE menu in the PRINTING submenu. Also on the PRINTING submenu, set DUPLEX BINDING to LONG EDGE or SHORT EDGE. (For more information, see Layout options for printing on both sides of paper.)
• The rear output bin must be closed to use the duplexer. Opening the rear output bin disables the duplexer.

Orientation of paper for duplexing

Several kinds of paper (such as letterhead, preprinted paper, prepunched paper, and paper with watermarks) require a specific orientation for duplex printing. The duplexer prints the second side of paper first. The proper orientation of the paper in the trays is shown below.

1 Tray 1 2 All other trays

For tray 1, load the front side facing down and the top edge toward you. For all other trays, load the front side facing up and the top edge toward the printer.

Layout options for printing on both sides of paper

The four duplex orientation options are shown below. These options can be selected in the printer driver (the preferred method) or at the printer control panel. (If you use the printer control panel, go to Configure Device menu, then the Printing submenu. Select DUPLEX BINDING. On the PCL submenu, select a setting for ORIENTATION.)

Illustration showing four sequential steps of a document folding or writing process, labeled 1 to 4.

1. Long-edge landscape* This layout is often used in accounting, data processing, and spreadsheet programs. Every other printed image is oriented upside-down. Facing pages are read continuously from top to bottom.

2. Short-edge landscape Each printed image is oriented right-side-up. Facing pages are read from top to bottom on the left page, then from top to bottom on the right page.

3. Long-edge portrait This is the default printer setting, and the most common layout used, with every printed image oriented right-side-up. Facing pages are read from top to bottom on the left page, then from top to bottom on the right page.

4. Short-edge portrait* This layout is often used with clipboards. Every other printed image is oriented upside-down. Facing pages are read continuously from top to bottom.

* When using Windows drivers, select Flip Pages Up to get the designated binding options.

To duplex with the optional duplex-printing accessory

1. Insert enough paper into one of the trays to accommodate the print job. If you are loading special paper such as letterhead, load it in one of the following ways:

2. For tray 1, load the letterhead paper with the front side down, bottom-edge first.

3. For all other trays, load the letterhead paper with front side up, and the top edge toward the back of the tray.

CAUTION

Do not load paper that is heavier than 105 g/m^2 (28 lb bond). Jamming could result.

1. Open the printer driver (see Changing the settings for a print job).

2. On the Finishing tab, click Print on Both Sides. For Macintosh, click File, click Print, and then click Layout.

3. Click OK.

4. Send the print job to the printer.

NOTE

The paper that you are printing on will partially come out of the top output bin during duplexing. Do not pull on the paper until duplexing is complete. During duplexing, the duplexer will not function if the rear output bin is open.

To duplex manually

If the printer does not have a duplexer installed, follow these instructions to manually print on both sides. Before attempting to duplex manually, ensure that the printer driver is set to enable manual duplexing. The procedure varies according to the operating system that you are using. For details, see Using the printer drivers. Look for the instructions in the column labeled "To change configuration settings."

NOTE

These instructions are for Windows. To duplex manually with Mac OS 9, perform a custom software installation and load the plug-in for booklet or manual duplex printing. Manual duplexing is not supported for Mac OS X.

1. Insert enough paper into one of the trays to accommodate the print job. If you are loading special paper such as letterhead, load it in one of the following ways:
2. For tray 1, load the letterhead paper with the front side down, bottom-edge first.

3. For all other trays, load the letterhead paper with front side up, and the top edge toward the back of the tray.

4. Open the printer driver (see Changing the settings for a print job).

5. On the Finishing tab, select Print on Both Sides (Manually).

6. Click OK.

7. Send the print job to the printer.

8. Go to the printer. After the first sides have finished printing, remove any blank paper that is remaining in tray 1. Insert the printed stack with the blank side up, top-edge first. You must print the second side from tray 1.

9. If prompted by a message at the control-panel display, press √ (SELECT button).

NOTE

If the number of total sheets exceeds the tray 1 capacity for manual duplex jobs, you must repeat steps 6 and 7 each time paper is inserted until the duplexing job is complete.

Canceling a print job

You can cancel a print job from a software program or a print queue, or by pressing the STOP button on the printer control panel.

• If the printer has not started printing, first try to cancel the job within the software program that sent the print job.
• If the print job is waiting in a print queue or print spooler such as the Printers group on a Windows computer or Print Monitor on a Macintosh computer, delete the job there.
• If the print job is already printing, press the STOP button. The printer will finish printing any pages that are already moving through the printer and delete the rest of the print job.

If the control-panel status lights continue to cycle after a job has been canceled, the computer is still sending the job to the printer. Either delete the job from the print queue or wait until the computer has finished sending data (the printer will return to the ready state, with the Ready light on).

Pressing STOP cancels only the current job in the printer. If more than one print job is in printer memory, STOP must be pressed once for each job.

Using the printer driver

The printer driver provides access to the printer features and allows the computer to communicate with the printer. This section provides instructions for printing when setting options are set from the printer driver.

If possible, try to set printing features from the software program in which you are working or from the Print dialog box. You can set the printer features this way for most Windows and Macintosh software programs. If a setting is not available in the software program or printer driver, you must set it at the printer control panel.

For more information about printer-driver features, see the printer-driver online Help. For more information about printing from a specific software program, see the documentation for the program.

NOTE

Printer-driver settings override control panel settings. Software program settings override both printer-driver settings and control panel settings.

Using job-storage features

The printer supports four distinct job-storage features that you can use to initiate printing from the printer control panel after the print job is sent from the computer:

• Quick copy jobs
  • Proof and hold jobs
• Private jobs
• Stored jobs

Some features are available without an optional hard disk installed, but to use all of the job-storage features, you must install an optional hard disk accessory in the printer and then properly configure the drivers. To support job-storage features for complex jobs, HP recommends that you install additional memory. For information about ordering an optional hard disk or more memory, see Part numbers.

Make sure that you identify your jobs in the printer driver before printing. Using default names might overwrite previous jobs that have the same default name or cause the job to be deleted.

NOTE

If you turn the printer power off, all quick copy, proof and hold, and private jobs are deleted. A job can also be deleted at the printer control panel.

Quick copying a job

The quick copy feature prints the requested number of copies of a job and stores a copy on the optional hard disk or, if a hard disk is not installed, it stores the copy on the RAM disk. Additional copies of the job can be printed later. This feature can be turned off in the printer driver.

For more information about specifying the number of quick copy jobs that can be stored, see Changing printer-control-panel configuration settings.

Using the embedded Web server

Use the embedded Web server to view printer and network status and to manage printing functions from your computer instead of from the printer control panel. The following are examples of what you can do using the embedded Web server:

• View printer-control status information.
- Set the type of media that is loaded in each tray.
• Determine the remaining life for all supplies and order new ones.
• View and change tray configurations.
• View and change the printer control-panel menu configuration.
• View and print internal pages.
- Receive notification of printer and supplies events.
• View and change network configuration.

The embedded Web server feature requires at least 48 MB of RAM and an HP Jetdirect print server in order to connect to your network.

To use the embedded Web server, you must have Microsoft Internet Explorer 5.01 or later or Netscape 6.2 or later for Windows, Mac OS, and Linux (Netscape only). Netscape Navigator 4.7 is required for HP-UX 10 and HP-UX 11. The embedded Web server works when the printer is connected to an IP-based network. The embedded Web server does not support IPX-based printer connections. You do not have to have Internet access to open and use the embedded Web server.

When the printer is directly connected to a computer, the embedded Web server is supported for Windows 98 and later. In order to use the embedded Web server with a direct connection, you must select the Custom installation option when you install the printer driver. Select the option to load the HP Toolbox. The proxy server is installed as part of the HP Toolbox software.

Managing and configuring printer drivers

Your system or network administrator can use the driver management and configuration solution to configure printer drivers before you install and deploy them within your environment. This is helpful when you configure printer drivers for multiple workstations or printers that share the same configuration.

When you preconfigure your printer driver to match the printer hardware, you can gain access to all of the printer accessories through the driver. You can also configure most driver feature settings. Five of the driver features can be "locked." This means that you can choose not to allow users to change the duplex, print color as gray, input tray, output tray, and media type settings. (Some features might not apply to all printers. For example, some printers do not include color printing or duplexing.)

The driver management and configuration solution saves time and reduces management costs. Previously, if an administrator wanted to configure printer drivers, the configuration had to be completed at each client workstation. Because the driver management and configuration solution offers multiple configuration options, administrators can create a single configuration, in a central location, that best fits their software installation and deployment strategy.

The driver management and configuration solution also gives administrators more control over their printing environment, because they can deploy drivers that share the same configuration across an entire organization. They can use the "lock" feature to support organization initiatives. For example, if a printer includes a duplexer, locking the duplex setting ensures that all print jobs are printed on two sides to save paper. All of the controls can be deployed from a single computer.

Two methods are available:

• HP Web Jetadmin software plug-in
- Customization utility

Regardless of the configuration method that is used, one configuration can be shared by all printer drivers for a given printer model with one pass through either the plug-in or the utility. The single configuration provides support for multiple operating systems, printer driver languages, and localized language versions.

A single configuration file is associated with all supported drivers, and can be modified by using either the plug-in or the utility.

HP Web Jetadmin software plug-in

A driver management and configuration plug-in is available for the HP Web Jetadmin software. You can use the plug-in to configure the printer drivers before installation and deployment. This method for managing and controlling printer drivers provides a complete, end-to-end solution that you can use to set up and configure the printer, the print path (queue), and the client computers or workstations. The following activities are included in the workflow:

• Discover and configure the printer(s).
- Discover and configure the print path on the server(s). You can have multiple servers configured in a batch, or multiple printers (of the same model type) using a single server.
- Obtain the printer driver(s). You can install multiple drivers for each print queue that is connected to a server in environments that support multiple operating systems.
- Run the configuration editor (the editor is not supported for some older drivers).

• Deploy the configured printer drivers to the server(s).
• Instruct the end-users to connect to the print server. The configured driver for their operating system is automatically deployed to their computer.

Administrators can use the HP Web Jetadmin software plug-in to deploy configured printer drivers using a silent, batch, or remote process. Obtain the HP Web Jetadmin software plug-in from http://www.hp.com/go/webjetadmin_software.

Customization utility

Administrators can use a customization utility to create a custom installation package that includes only the components that are needed within a specific organization or operating environment. The customization utility is available in two places:

• On the CD-ROM that comes with the printer (the utility is one of the installer options)
• In the printing system software that is available for downloading from the HP Web site for the printer model.

The installation procedure prompts the administrator to select components from the contents of the printing system. During this process, the administrator is prompted to configure the printer driver settings, if the selected drivers support preconfiguration. The process yields a customized installation package that the administrator can deploy to install the configured printer drivers on the client computers and workstations. The customization utility supports silent and batch operations.

Configuring e-mail alerts

You can use HP Web Jetadmin or the embedded Web server to configure the system to alert you to problems with the printer. The alerts take the form of e-mail messages to the e-mail account or accounts that you specify.

You can configure the following information:

• The device that you want to monitor (in this case, the printer)
- What alerts are to be received (for example, alerts for jams, paper out, ORDER CARTRIDGE, REPLACE CARTRIDGE, and cover open)
• The e-mail account to which the alerts should be forwarded

This section provides information about HP print cartridges, their life expectancies, how to store them, and how to identify genuine HP supplies. Information also appears about non-HP print cartridges.

• HP print cartridges
• Non-HP print cartridges
• Print-cartridge authentication
• Print-cartridge storage
• Print-cartridge life expectancy
- Checking the supply level
• Cartridge-low and cartridge-out conditions

HP print cartridges

When you use a genuine HP print cartridge, you can obtain several types of information, such as the following:

• Amount of toner remaining
• Estimated number of pages remaining
• Number of pages printed

Non-HP print cartridges

Hewlett-Packard Company cannot recommend use of non-HP print cartridges, either new or remanufactured. Because they are not HP products, HP cannot influence their design or control their quality. Service or repair required as a result of using a non-HP print cartridge will not be covered under the printer warranty.

Using genuine HP supplies ensures the availability of all HP printing features.

Print-cartridge authentication

The printer will let you know if a print cartridge is not a genuine HP print cartridge when you insert it into the printer. If you believe that you purchased a genuine HP supply, visit us at http://www.hp.com/go/anticounterfeit.

Print-cartridge storage

Do not remove the print cartridge from its package until you are ready to use it.

Always store the print cartridge in the proper environment. The temperature should be between -20^ and 40^ ( -4^ to 104^ ). The relative humidity should be between 10% and 90%.

CAUTION

To prevent damage to the print cartridge, do not expose it to light for more than a few minutes.

Print-cartridge life expectancy

The life of the print cartridge depends on the amount of toner that print jobs require and the length of life for the components inside the cartridge. When printing text at 5% coverage (typical for a business letter), the HP print cartridge lasts an average of 10,000 (Q5942A) or 20,000 (Q5942X) pages.

At any time, you can verify life expectancy by checking the supply level, as described in Checking the supply level.

Checking the supply level

You can check the supply (toner) level by using the printer control panel, the embedded Web server, HP Toolbox software, or HP Web Jetadmin.

To check the supply level by using the control panel

1. Press M ENU to open the menus.
2. Use ▲ (UP button) or ▼(DOWN button) to scroll to INFORMATION, and then press √ (SELECT button).
3. Use ▲ (UP button) or ▼(DOWN button) to scroll to PRINT SUPPLIES STATUS PAGE, and then press √ (SELECT button). See Supplies status page for information about the supplies status page.

To check the supply level by using the embedded Web server

1. In your Web browser, type the IP address for the printer home page. This takes you to the printer status page. (See Opening the embedded Web server.)
2. On the left side of the screen, click Supplies Status. This takes you to the supplies status page, which provides supply level information. (See Supplies status page for information about the supplies status page.)

To check the supply level by using the HP Toolbox software

You can configure HP Toolbox to notify you when the print cartridge is low. You can choose to receive alerts by e-mail or as a pop-up message or taskbar icon. To check the supplies status by using the HP Toolbox software, click the Status tab, then click Supplies Status.

To check the supply levels by using HP Web Jetadmin

In HP Web Jetadmin, select the printer device. The device status page shows supply-level information.

Cartridge-low and cartridge-out conditions

The printer alerts you if the print cartridge is low on toner or out of toner.

When the cartridge is low on toner or drum life

When the cartridge is low, the printer control panel shows the ORDER CARTRIDGE message. For the HP LaserJet 4250 series, the message first appears when about 15% (10,000-page cartridge) or about 8% (20,000-page cartridge) of the life remains in the print cartridge. For the HP LaserJet 4350 series, the message first appears when about 25% (10,000-page cartridge) or about 15% (20,000-page cartridge) of the life remains in the print cartridge. This percentage is set with the intent of providing approximately 2 weeks of typical use before the cartridge is depleted. You should have time to purchase a new cartridge before the old cartridge is depleted.

The default is for the printer to continue printing until the cartridge runs out, but you might prefer to have the printer stop instead of continuing when the ORDER CARTRIDGE message first appears—for example, if you want print quality to remain consistently high during print jobs, or if you do not want the cartridge to run out during a long print job. To configure the printer to stop, in the CONFIGURE DEVICE menu, under SYSTEM SETUP, set CARTRIDGE LOW to STOP. Then, when REPLACE CARTRIDGE appears, the printer will stop printing. You can resume printing by pressing √ (SELECT button) for each print job.

When the cartridge is out of toner or drum life

The REPLACE CARTRIDGE message appears in one of these situations:

- When the print cartridge is out of toner. If CARTRIDGE OUT is set to CONTINUE (in the SYSTEM SETUP submenu of the CONFIGURE DEVICE menu), the printer continues printing without interaction until the cartridge reaches the end of drum life. HP does not guarantee print quality after the REPLACE CARTRIDGE message first appears. Replace the print cartridge as soon as possible. (See Ordering parts, accessories, and supplies.) The REPLACE CARTRIDGE message remains until you replace the print cartridge. If CARTRIDGE OUT is set to STOP, the printer stops printing until you replace the print cartridge or resume printing by configuring the printer to continue: In the CONFIGURE DEVICE menu, under SYSTEM SETUP, set CARTRIDGE OUT to CONTINUE.

- When the drum life of the print cartridge is out. You must replace the print cartridge to continue printing. No override is possible, even if toner remains in the cartridge. (See Ordering parts, accessories, and supplies.) This situation occurs to protect the printer.

Cleaning the printer

Use the cleaning procedure on the following page every time you change the print cartridge or whenever print-quality problems occur. As much as possible, keep the printer free from dust and debris.

• Clean the outside of the printer with a slightly water-dampened cloth.
  • Clean the inside with a dry, lint-free cloth.

CAUTION

Do not use ammonia-based cleaners on or around the printer. While cleaning the printer, be careful not to touch the transfer roller (the black, rubber roller located underneath the print cartridge). Skin oils on the roller can cause print-quality problems.

1. Reinstall the print cartridge, close the top cover, plug in the power cord, and turn the printer power on.

Cleaning the fuser

Run the printer cleaning page to keep the fuser free of toner and paper particles that can sometimes accumulate. Accumulation of toner and particles can cause specks to appear on the front or back side of your print jobs.

To ensure optimum print quality, HP recommends that you use the cleaning page every time you replace the print cartridge or on an automatic interval that you can set up. If you have an optional duplexer installed, you must run cleaning pages manually.

The cleaning procedure takes about 2.5 minutes to complete. A CLEANING message appears on the printer control panel display while the cleaning is taking place.

Running the cleaning page manually

In order for the cleaning page to work properly, print the page on copier-grade paper (not bond, heavy, or rough paper).

To run the cleaning page manually

1. If a duplexer is installed, open the rear output bin.
2. Press M ENU to open the menus.
3. Use ▲ (UP button) or ▼(DOWN button) to scroll to CONFIGURE DEVICE, and then press √ (SELECT button).
4. Use ▲ (UP button) or ▼(DOWN button) to scroll to PRINT QUALITY, and then press √ (SELECT button).
5. Use ▲ (UP button) or ▼(DOWN button) to scroll to PROCESS CLEANING PAGE, and then press √ (SELECT button).
6. If a duplexer is installed, close the rear output bin.

Running the cleaning page automatically

Using the procedure below, you can set the printer to print cleaning pages automatically at an interval that you select. In order for the cleaning page to run without intervention, you must keep the selected size and plain paper type available in the printer. The printer will not interrupt a printing job in process.

To run the cleaning page automatically

1. Press M ENU to open the menus.
2. Use ▲ (UP button) or ▼(DOWN button) to scroll to CONFIGURE DEVICE, and then press √ (SELECT button).
3. Use ▲ (UP button) or ▼(DOWN button) to scroll to PRINT QUALITY, and then press √ (SELECT button).
4. Use ▲ (UP button) or ▼(DOWN button) to scroll to AUTO CLEANING, and then press √ (SELECT button).
5. Use ▲ (UP button) or ▼(DOWN button) to scroll to ON, and then press √ (SELECT button).
6. Use ▲ (UP button) or ▼(DOWN button) to scroll to CLEANING INTERVAL, and then press √ (SELECT button).
7. Use ▲ (UP button) or ▼(DOWN button) to scroll to the desired interval between 1,000 and 20,000 pages, and then press √ (SELECT button) to save your selection.
8. Use ▲ (UP button) or ▼(DOWN button) to scroll to AUTO CLEANING SIZE, and then press √ (SELECT button).
9. Use ▲ (UP button) or ▼(DOWN button) to scroll to the paper size that you want the printer to use for cleaning pages (A4 or LETTER), and then press √ (SELECT button) to save your selection.

The printer automatically prints a cleaning page at the interval and page size that you selected. You can discard the output page created by the cleaning process.

Performing preventive maintenance

You should replace certain parts when the PERFORM PRINTER MAINTENANCE message appears on the printer control panel display. This will help ensure that your printer maintains optimum performance.

The maintenance message will appear every 200,000 pages. The message can be temporarily cleared for approximately 10,000 pages by using the CLEAR MAINTENANCE MESSAGE item on the Resets submenu. (See Resets submenu.) To check the number of pages the printer has printed since new maintenance-kit components were installed, print either a configuration page or a supplies status page. (See Configuration page or Supplies status page for details.)

To order the printer maintenance kit, see Part numbers. The kit includes:

• fuser
• rollers (transfer, pickup, and feed)
  • installation instructions

NOTE

The printer maintenance kit is a consumable item and is not covered under the original printer warranty or under most extended warranties.

After a maintenance kit is installed, the maintenance-kit counter must be reset.

To reset the maintenance-kit counter

1. Turn the printer power off and then on.
2. When XXX appears on the control-panel display, press and hold down √ (SELECT button). Continue holding down √(S ELECT button) until all three printer control panel lights flash once, and then stay on. This might take up to 10 seconds.

Solving general printing problems

In addition to the issues and solutions that are listed in this section, see Troubleshooting common Macintosh problems if you are using a Macintosh computer, and see Troubleshooting common PostScript problems if you are using the PS driver.

Printer selects media from the wrong tray.

Cause	Solution
The tray selection in the software program might be incorrect.	For many software programs, the paper tray selection is found on thePage Setupmenu within the program.Remove any media in other trays to make the printer select from the correct tray.For Macintosh computers, use the HP LaserJet Utility to change the priority of the tray.
The configured size does not match the size of the media that is loaded in the tray.	Through the control panel, change the configured size to match the size of the media that is loaded in the tray.

Printer does not pull paper from tray.

Cause	Solution
The tray is empty. Load paper in the tray.
The paper guides are set incorrectly.	To set the guides correctly, see Loading trays.For the 500-sheet paper tray, make sure that the leading edge of the paper stack is even. An uneven edge can prevent the lift plate from rising.

Paper curls when it exits the printer.

Cause	Solution
The paper curls when it exits to the top output bin.	Open the rear output bin to allow the paper to exit in a straight path through the printer.Turn over the paper that you are printing on.Reduce the fusing temperature to reduce the curling. (SeeSelecting the correct fuser mode.)

First sheet of media jams in the print-cartridge area.

Cause	Solution
A combination of high humidity and high temperature is affecting the media.	Adjust the printer for high humidity and high temperature conditions.

Print job is extremely slow.

Cause	Solution
The job might be very complex.The maximum speed of the printer cannot be exceeded even when more memory is added.Printing speeds might be automatically reduced when printing on custom-sized media.Note: Slower speeds are expected when printing on narrow paper, when printing from tray 1, or when using the HIGH 2 fuser mode.	Reduce the complexity of the page or try adjusting the print-quality settings. If this problem occurs frequently, add memory to the printer.
You are printing a PDF or PostScript (PS) file but are using a PCL printer driver.	Try using the PS printer driver rather than the PCL printer driver. (You can usually do this from a software program.)
In the printer driver, Optimize for: is set to cardstock, heavy, rough, or bond paper.	In the printer driver, set the type to plain paper (see Printing by type and size of media (locking trays)).Note: If you change the setting to plain paper, the print job will print faster. However, if you are using heavy media, for best results leave the printer driver set to heavy even though printing might be slower.

Print job prints on both sides of the paper.

Cause	Solution
The printer is set for duplexing.	SeeChanging the settings for a print job to change the setting, or see the online Help.

Print job contains only one page but the printer processes the back side of the page as well (the page comes part of the way out, and then goes back into the printer).

Cause	Solution
The printer is set for duplexing. Even if the print job contains only one page, the printer also processes the back side.	SeeChanging the settings for a print job to change the setting, or see the online Help.Do not try to pull the page out of the printer before duplexing is complete. Jamming might result.

Pages print, but are totally blank.

Cause	Solution
The sealing tape might still be in the print cartridge.	Remove the print cartridge and pull out the sealing tape. Reinstall the print cartridge.
The file might have blank pages. Check the file to make sure that it does not contain blank pages.

The printer prints, but the text is wrong, garbled, or incomplete.

Cause	Solution
The printer cable is loose or defective. Disconnect	the printer cable and reconnect it.Try a print job that you know works. If possible, attach the cable and printer to another computer and try a print job that you know works. Finally, try a new cable.
The printer is on a network or sharing device and is not receiving a clear signal.	Disconnect the printer from the network and use a parallel or USB cable to attach it directly to a computer. Print a job that you know works.
The wrong driver was selected in the software.	Check the software's printer selection menu to make sure that an HP LaserJet 4250 or 4350 series printer is selected.
The software program is malfunctioning. Try printing	a job from another program.

The printer does not respond when you select Print in the software.

Cause	Solution
The printer is out of media. Add media.
The printer might be in the manual feed mode. Change the printer from manual-feed mode.
The cable between the computer and the printer is not connected properly.	Disconnect and reconnect the cable.
The printer cable is defective. If possible, attach the cable to another computer and print a job that you know works. You might also try using a different cable.
The wrong printer was selected in the software.	Check the software printer selection menu to make sure that an HP LaserJet 4250 or 4350 series printer is selected.
The printer might have a jam. Clear any jams, paying careful attention to the duplexer area (if your model has a duplexer). See Clearing jams.
The software for the printer is not configured for the printer port.	Check the software's printer selection menu to make sure that it is using the correct port. If the computer has more than one port, make sure that the printer is attached to the correct one.
The printer is on a network and is not receiving a signal.	Disconnect the printer from the network and use a parallel or USB cable to attach it directly to a computer. Reinstall the printing software. Print a job that you know works. Clear any stopped jobs from the print queue.
The printer is not receiving power. If no lights are on, check the power cord connections. Check the power switch. Check the power source.

The printer does not respond when you select Print in the software.

Cause	Solution
The printer is malfunctioning. Check the control-panel display for messages and lights to determine if the printer is indicating an error. Note any message and seeInterpreting control-panel messages.

Guidelines for using paper

For best results, make sure the paper is of good quality, and free of cuts, nicks, tears, spots, loose particles, dust, wrinkles, voids, and curled or bent edges.

If you are unsure what type of paper you are loading (such as bond or recycled), check the label on the package of paper.

For a complete list of supported media, see Supported sizes of print media.

The following problems with paper cause print quality deviations, jamming, or even damage to the printer.

Symptom Problem with paper $	Solution
Poor print quality or toner adhesion	The paper is too moist, too rough, too heavy, too smooth, or it is embossed or from a faulty paper lot.	Try another kind of paper, between 100 and 250 Sheffield, and with 4 to 6% moisture content.
Dropouts, jamming, curl The paper	has been stored improperly.The paper varies from side to side.	Store paper flat in its moisture-proof wrapping.Turn the paper over.
Excessive curl The paper is too moist, has the wrong grain direction, or is of short-grain construction.The paper varies from side to side.	Open the rear output bin, or use long-grain paper.Turn the paper over.
Jamming, damage to printer The paper has cutouts or perforations.	Use paper that is free of cutouts or perforations.
Problems with feeding The paper has ragged edges, or it is from a faulty paper lot.The paper varies from side to side.The paper is too moist, too rough, too heavy, or too smooth.It has the wrong grain direction, is of short-grain construction, or it is embossed.	Use high-quality paper that is made for laser printers.Turn the paper over.Try another kind of paper, between 100 and 250 Sheffield, and with 4 to 6% moisture content.Open the rear output bin, or use long-grain paper.

NOTE

Do not use letterhead paper that is printed with low-temperature inks, such as those used in some types of thermography. Do not use raised or embossed letterhead. The printer uses heat and pressure to fuse toner to the paper. Make sure that any colored paper or preprinted forms use inks that are compatible with this fusing temperature (200°C or 392°F for 0.1 second).

CAUTION

Failure to follow these guidelines could cause jams or damage to the printer.

Printing special pages

Special pages within the memory of the printer can help you to diagnose and learn about problems with your printer.

- Configuration page

The configuration page lists many of the current settings and properties of the printer. For information about how to print the configuration page, see Configuration page. If you have an HP Jetdirect print server installed, a second page prints that lists all of the HP Jetdirect information.

- Font list

You can print a font list using the control panel (see PS or PCL font list) or (for Macintosh computers) the HP LaserJet Utility (see HP LaserJet Utility).

• Supplies status page

Use the supplies status page to obtain information about the print cartridge that is installed in the printer, the amount of life that is left in the print cartridge, and the number of pages and jobs that have been processed (see Supplies status page).

Clearing jams

If a jam message appears on the printer control-panel display, look for jammed paper or other print media in the locations that are indicated in the figure below. Then see the procedure for clearing the jam. You might need to look for media in other locations than those that are indicated in the jam message. If the location of the jam is not obvious, look first in the top-cover area underneath the print cartridge.

When clearing jams, be very careful not to tear jammed media. If a small piece of media is left in the printer, it could cause additional jams. If jams are a recurring problem, see Solving repeated jams.

1. Insert the staple cartridge into the stapler unit, and rotate the stapler unit toward the rear of the printer until the unit snaps into place.

Medical illustration showing a hand operating a device with a magnified inset highlighting the device's internal structure.

The stapler needs to reload after clearing a staple jam, so the first few documents (up to five) might not be stapled. If a print job is sent and the stapler is jammed or is out of staples, the job will still print as long as the path to the stacker bin is not blocked.

Solving repeated jams

If paper jams occur frequently, try the following:

- Check all the jam locations. (See Clearing jams.) A piece of media might be stuck somewhere in the printer. Even a small torn piece of media in the printer path can cause repeated jams.

- Check that the trays are properly adjusted. (See Loading trays.) The guides should click into place without being too tight against the media.

- Check that media is correctly loaded in the trays and that the trays are not overfilled. Make sure that the stack is under the tabs and below the maximum-height indicators. See Loading trays.

- Check that all trays and paper-handling accessories are completely inserted into the printer. (If a tray is opened during a print job, this might cause a jam.)

- Check that all covers and doors are closed. (If a cover or door is opened during a print job, this might cause a jam.)

• Try printing to a different output bin. (See Understanding media output options.)

- The sheets might be sticking together. Try bending the stack to separate each sheet. Do not fan the stack.

• If you are printing from tray 1, try reducing the size of the stack.

- If you are printing from the optional envelope feeder, make sure that it is loaded correctly (with the bottom envelopes in slightly farther than the top envelopes). (See Loading envelopes in the optional envelope feeder.)

- If you are printing small sizes, feed the media with the short-edge first. (See Guidelines for custom-size paper.)

• Turn over the stack of media in the tray. Also try rotating the paper 180 degrees.

- Check the characteristics of the paper or other print media that you are using. Use only media that meets HP specifications. (See Paper specifications.) Try using different media to see if the problem goes away. Do not use curled, deformed, damaged, or irregular media.

- Check that the environmental conditions for the printer are met. (See Operating environment.)

- Avoid using paper that has already been used in a printer or copier.

• Try using paper from a freshly opened ream.

• Try a different brand of paper.
- Do not print on both sides of envelopes or transparencies. (See Printing envelopes or Printing on transparencies.)
- Print only on full sheets of labels and do not print on both sides of label sheets. (See Printing on labels.)
- Check that the power supplied to the printer is steady and meets printer specifications. (See Electrical specifications.)
- Clean the printer. (See Cleaning the printer.)
- Perform preventive printer maintenance if maintenance is due. See Loading staples.

Understanding printer messages

Printer messages appear on the printer control panel display to relay the normal status of the printer (such as Processing...) or an error condition (such as CLOSE TOP COVER) that needs attention. Interpreting control-panel messages lists the most common messages that require attention or that might raise questions. Messages are listed in alphabetical order first, with numeric messages at the end of the list.

Using the printer online Help system

This printer features an online Help system on the control panel that provides instructions for resolving most printer errors. Certain control panel messages alternate with instructions about gaining access to the online Help system.

Whenever a message alternates with For help press, press ? (HELP button) to view the help and use ▲ (UP button) and ▼(DOWN button) to scroll through the message.

To exit the online Help system, press M _ENU .

Resolving persistent messages

Some messages (for example, requests to load a tray or a message that a previous print job is still in the printer memory) allow you to press √ (SELECT button) to print, or to press STOP to clear the job and eliminate the message.

If a message persists after performing all of the recommended actions, contact an HP-authorized service or support provider. (See HP customer care or go to http://www.hp.com/support/lj4250 or http://www.hp.com/support/lj4350.)

Correcting print-quality problems

This section helps you define print-quality problems and what to do to correct them. Often print- quality problems can be handled easily by making sure that the printer is properly maintained, using print media that meets HP specifications, or running a cleaning page.

Print-quality checklist

General print-quality problems can be solved by following the checklist below.

• Check the printer driver to make sure that you are using the best available print quality option (see Selecting print-quality settings).
• Try printing with one of the alternative printer drivers. The most recent printer drivers area available for download from http://www.hp.com/go/lj4250_software or http://www.hp.com/go/lj4350_software.
• Clean the inside of the printer (see Cleaning the printer).
• Check the paper type and quality (see Paper specifications).
• Check to make sure that EconoMode is off in the software (see Using EconoMode (draft) printing ).
• Troubleshoot general printing problems (see Solving general printing problems).
• Install a new HP print cartridge, and then check the print quality again. (See the instructions provided with the print cartridge.)

NOTE

If the page is totally blank (all white) check to make sure that the sealing tape is removed from the print cartridge and ensure that the print cartridge is installed correctly. Newer printers have been optimized to print characters more accurately. This might result in characters that look lighter or thinner than you are used to from your older printer. If the page is printing images darker than those from an older printer, and you want the images to match the older printer, make these changes in your printer driver: on the Finishing tab, select Print Quality, select Custom, click Details, and click the check box for Print Images Lighter.

Image defect examples

Use the examples in this image-defect table to determine which print-quality problem you are experiencing, and then see the corresponding reference pages to troubleshoot. These examples identify the most common print-quality problems. If you still have problems after trying the suggested remedies, contact HP Customer Support. (See HP customer care.)

• Change the tone (darkness) of the field that the repeated image appears in.
• Change the order in which the images are printed. For example, have the lighter image at the top of the page, and the darker image farther down the page.
• From your software application, rotate the whole page 180^ to print the lighter image first.
• If the defect occurs later in a print job, turn the printer power off for 10 minutes, and then turn the printer power on to restart the print job.

Troubleshooting network printing problems

NOTE

HP recommends that you use the printer CD-ROM to install and set up the printer on a network.

• Print a configuration page (see Configuration page). If an HP Jetdirect print server is installed, printing a configuration page also prints a second page that shows the network settings and status.
• See the HP Jetdirect Print Server Administrator's Guide on the printer CD-ROM for help and for more information about the Jetdirect configuration page. To reach the guide, select the appropriate print server series, select the appropriate print server product, and then click troubleshoot a problem.
  • Try printing the job from another computer.
• To verify that a printer works with a computer, use a parallel or USB cable to connect it directly to a computer. You will have to reinstall the printing software. Print a document from a program that has printed correctly in the past. If this works, a problem with the network might exist.

Cause

Solution

Close all software programs, restart Windows, and try again.Select a different printer driver. If the HP LaserJet 4250 or 4350 series PCL 6 driver is selected, switch to a PCL 5e or PS printer driver. You can usually do this from a software program.Delete all temp files from the Temp subdirectory. You can determine the name of the directory by editing the AUTOEXEC.BAT file and looking for the statement "Set Temp =". The name after this statement is the temp directory. It is usually C:\TEMP by default, but can be redefined.See the Microsoft Windows documentation that came with your computer for more information about Windows error messages.

Control panel menus

You can perform most routine printing tasks from the computer by using the program or printer driver. These two methods are the most convenient way to control the printer, and they will override the printer-control-panel settings. See the Help file for your program, or, for more information about gaining access to the printer driver, see Using the printer driver.

You can also control the printer by changing settings at the printer control panel. Use the control panel to gain access to printer features that are not supported by the program or printer driver.

You can print a menu map at the printer control panel that shows the settings with the currently selected values (see Menu map. The sections that follow list the settings and possible values. In the Values column, the default value for each setting is the one with an asterisk (*) next to it.

Some menus or menu items appear only if certain options are installed in the printer.

Printing and paper storage environment

Ideally, the printing and paper storage environment should be at or near room temperature, and not too dry or too humid. Remember paper is hygroscopic; it absorbs and loses moisture rapidly.

Heat works with humidity to damage paper. Heat causes the moisture in paper to evaporate, while cold causes it to condense on the sheets. Heating systems and air conditioners remove most of the humidity from a room. As paper is opened and used, it loses moisture, causing streaks and smudging. Humid weather or water coolers can cause the humidity to increase in a room. As paper is opened and used it absorbs any excess moisture, causing light print and dropouts. Also, as paper loses and gains moisture it can distort. This can cause jams.

As a result, paper storage and handling are as important as the paper-making process itself. Paper storage environmental conditions directly affect the feed operation.

Care should be taken not to purchase more paper than can be easily used in a short time (about 3 months). Paper stored for long periods might experience heat and moisture extremes, which can cause damage. Planning is important to prevent damage to a large supply of paper.

Unopened paper in sealed reams can remain stable for several months before use. Opened packages of paper have more potential for environmental damage, especially if they are not wrapped with a moisture-proof barrier.

The paper storage environment should be properly maintained to ensure optimum printer performance. The required condition is 20^ to 24^ C ( 68^ to 75^ F), with a relative humidity of 45% to 55%. The following guidelines should be helpful when evaluating the paper's storage environment:

• Paper should be stored at or near room temperature.
- The air should not be too dry or too humid (due to the hygroscopic properties of paper).
- The best way to store an opened ream of paper is to rewrap it tightly in its moisture-proof wrapping. If the printer environment is subject to extremes, unwrap only the amount of paper to be used during the day's operation to prevent unwanted moisture changes.

Envelopes

Envelope construction is critical. Envelope fold lines can vary considerably, not only between manufacturers, but also within a box from the same manufacturer. Successful printing on envelopes depends upon the quality of the envelopes. When selecting envelopes, consider the following components:

• Weight: The weight of the envelope paper should not exceed 105g / m^2 (28 lb) or jamming might occur.
• Construction: Prior to printing, envelopes should lie flat with less than 6 mm (0.25 inch) curl, and should not contain air.
  • Condition: Envelopes should not be wrinkled, nicked, or otherwise damaged.
• Temperature: You should use envelopes that are compatible with the heat and pressure of the printer.
  • Size: You should use only envelopes within the following size ranges.

• Minimum: 76 x 127 mm (3 x 5 inches)
• Maximum: 216 x 356 mm (8.5 x 14 inches)

Use only tray 1 or the optional envelope feeder to print envelopes. You might experience some jams when using any media with a length less than 178 mm (7 inches). This might be caused by paper that has been affected by environmental conditions. For optimum performance, make sure you are storing and handling the paper correctly (see Printing and paper storage environment). Choose envelopes in the printer driver (see Using the printer driver).

Envelopes with double side seams

Double side-seam construction has vertical seams at both ends of the envelope rather than diagonal seams. This style might be more likely to wrinkle. Be sure the seam extends all the way to the corner of the envelope as illustrated below.

Diagram showing two geometric shapes with numbered annotations and connecting lines, likely illustrating a physics or engineering concept.

1 Acceptable envelope construction
2 Unacceptable envelope construction

Envelopes with adhesive strips or flaps

Envelopes with a peel-off adhesive strip or with more than one flap that folds over to seal must use adhesives compatible with the heat and pressure in the printer. The extra flaps and strips might cause wrinkling, creasing, or even jams and might even damage the fuser.

Envelope margins

The following gives typical address margins for a commercial #10 or DL envelope.

Type of address Top margin Left margin
Return address 15 mm (0.6 inch)	15 mm (0.6 inch)
Delivery address 51 mm (2 inches)	89 mm (3.5 inches)

NOTE

For the best print quality, position margins no closer than 15 mm (0.6 inch) from the edges of the envelope. Avoid printing over the area where the envelope's seams meet.

Envelope storage

Proper storage of envelopes helps contribute to print quality. Envelopes should be stored flat. If air is trapped in an envelope, creating an air bubble, then the envelope might wrinkle during printing.

For more information, see Printing envelopes.

Labels

CAUTION

To avoid damaging the printer, use only labels recommended for laser printers. To prevent serious jams, always use tray 1 to print labels and always use the rear output bin. Never print on the same sheet of labels more than once or print on a partial sheet of labels.

Label construction

When selecting labels, consider the quality of each component:

• Adhesives: The adhesive material should be stable at 200°C (392°F), the printer's fusing temperature.
• Arrangement: Only use labels with no exposed backing between them. Labels can peel off sheets with spaces between the labels, causing serious jams.
• Curl: Prior to printing, labels must lie flat with no more than 13 mm (0.5 inch) of curl in any direction.
  • Condition: Do not use labels with wrinkles, bubbles, or other indications of separation.

For more information, see Printing on labels.

NOTE

Choose labels in the printer driver (see Using the printer driver).

Transparencies

Transparencies used in the printer must be able to withstand 200^ C ( 392^ F), the printer's fusing temperature.

CAUTION

To avoid damaging the printer, use only transparencies recommended for use in HP LaserJet printers, such as HP-brand transparencies. (For ordering information, see Part numbers.)

For more information, see Printing on transparencies.

NOTE

Choose transparencies in the printer driver (see Using the printer driver).

Printer memory and expansion

This section explains the memory features of the printer and provides steps for expansion.

• Printer memory
  • Installing CompactFlash cards
• Checking memory installation
  • Saving resources (permanent resources)
  • Installing EIO cards or mass storage devices

Overview

The printer comes with one dual inline memory module (DIMM) already installed. One additional DIMM slot and two CompactFlash slots are available for upgrading the printer with the following items:

• More printer memory—DIMMs (SDRAM) are available in 48, 64, 128, and 256 MB, for a maximum of 512 MB.
• CompactFlash font cards—Unlike standard printer memory, CompactFlash cards can be used to permanently store downloaded items, such as fonts and forms, even when the printer is off. These cards can also be used to enable the printer to print non-Roman characters.
• Other DIMM-and CompactFlash-based printer languages and printer options.

NOTE

Single inline memory modules (SIMMs) used in previous HP LaserJet printers are not compatible with the printer.

The printer also has two EIO slots for expanding the printer's capabilities with a mass storage device, such as an optional hard disk for storing forms and fonts, and for certain job-storage functions. The EIO slots can also be used for adding a wireless connections, a network card, or a connectivity card for serial or AppleTalk.

NOTE

Some HP LaserJet 4250 or 4350 series printers come with a network device already installed. The EIO slot can be used to provide networking capabilities in addition to those already built into the printer.

To find out how much memory is installed in the printer, or to find out what is installed in the EIO slots, print a configuration page. (See Configuration page.)

Printer memory

You might want to add more printer memory to the printer if you often print complex graphics, print PostScript (PS) documents, or use many downloaded fonts. Added memory also gives you more flexibility in supporting job-storage features, such as quick copying.

To install printer memory

CAUTION

Static electricity can damage DIMMs. When handling DIMMs, either wear an antistatic wrist strap or frequently touch the surface of the DIMM antistatic package, then touch bare metal on the printer.

The HP LaserJet 4250 or 4350 series printers come with one DIMM installed in slot 1. A second DIMM can be installed in slot 2. If desired, you can replace the DIMM installed in slot 1 with a higher-memory DIMM.

If you have not already done so, print a configuration page to find out how much memory is installed in the printer before adding more memory. (See Configuration page.)

Checking memory installation

After installing the DIMM or CompactFlash card, make sure that the installation was successful.

To verify that DIMMs or CompactFlash cards are installed correctly

1. Check that Ready appears on the printer control panel display when the printer power is turned on. If an error message appears, a DIMM or CompactFlash card might have been incorrectly installed. See Interpreting control-panel messages.
2. Print a new configuration page. (See Configuration page.)
3. Check the memory section on the configuration page and compare it to the configuration page that was printed before the memory installation. If the amount of memory has not increased, the DIMM or CompactFlash card might not be installed correctly, or the DIMM or CompactFlash card might be defective. Repeat the installation procedure. If necessary, install a different DIMM or CompactFlash card.

NOTE

If you installed a printer language (personality), check the "Installed Personalities and Options" section on the configuration page. This area should list the new printer language.

Saving resources (permanent resources)

Utilities or jobs that you download to the printer sometimes include resources (for example, fonts, macros, or patterns). Resources that are internally marked as permanent remain in the printer memory until you turn the printer power off.

Use the following guidelines if you use the page description language (PDL) ability to mark resources as permanent. For technical details, see an appropriate PDL reference for PCL or PS.

• Mark resources as permanent only when it is absolutely necessary that they remain in memory while the printer power is turned on.
• Send permanent resources to the printer only at the beginning of a print job and not while the printer is printing.

NOTE

Over-using permanent resources or downloading them while the printer is printing might affect printer performance or the ability to print complex pages.

Installing EIO cards or mass storage devices

Follow this procedure to install an EIO card or mass storage device (optional hard disk).

To install EIO cards or mass storage devices

1. Turn the printer power off.
2. Remove the two screws and cover plate from the EIO 1 or EIO 2 slot on the back of the printer.

NOTE

Do not discard the screws or the cover plate. Save them for future use if you remove the EIO card.

1. Install the EIO card or mass storage device in the EIO slot and tighten the screws.

Printer commands

Most programs do not require you to enter printer commands. See your computer and software documentation to find the method for entering printer commands, if needed.

PCL 6 and PCL 5e PCL 6 and PCL 5e printer commands tell the printer which tasks to perform or which fonts to use. This section provides a quick reference for users who are already familiar with PCL 6 and PCL 5e command structure.
HP-GL/2	The printer has the ability to print vector graphics using the HP-GL/2 graphics language. Printing in the HP-GL/2 language requires that the printer leave PCL 5e language and enter HP-GL/2 mode, which can be done by sending the printer PCL 5e code. Some programs switch languages through their drivers.
PJL	HP's Printer Job Language (PJL) provides control above PCL 5e and other printer languages. The four major functions provided by PJL are: printer language switching, job separation, printer configuration, and status readback from the printer. PJL commands can be used to change printer default settings.

NOTE

The table at the end of this section contains commonly used PCL 5e commands. (See Common PCL 6 and PCL 5 printer commands.) For a complete listing and explanation of how to use PCL 5e, HP-GL/2, and PJL commands, see the HP PCL/PJL Reference Set, which is available on CD-ROM (HP part number 5961-0975).

Understanding PCL 6 and PCL 5e printer command syntax

Before using printer commands, compare these characters:

Lowercase I: I Uppercase O: O
Number one: 1 Number 0: 0

Many printer commands use the lowercase letter I (I) and the number one (1), or the uppercase letter O (O) and the number zero (0). These characters might not appear on your screen as shown here. You must use the exact character and case specified for PCL 6 or PCL 5e printer commands.

The figure below explains the elements of a typical printer command (in this instance, a command for page orientation).

① E_c & ℓ # O ② ③ ④ ⑤

1 Escape character (begins the escape sequence)
2 Parameterized character
3 Group character
4 Value field (contains both alpha and numeric characters)
5 Termination character (uppercase)

Combining escape sequences

Escape sequences can be combined into one escape sequence string. Follow these three important rules when combining code:

1. The first two characters after the E_c character are the parameterized and group characters. These characters must be the same in all of the commands that are to be combined.
2. When combining escape sequences, change the uppercase termination character in each individual escape sequence to lowercase.
3. The final character of the combined escape sequence must be uppercase.

The following is an example of an escape sequence string that would be sent to the printer to select legal paper, landscape orientation, and eight lines per inch:

E_c\&I3AE_c\&I1OE_c\&I8D

The following escape sequence sends the same printer commands by combining them into a shorter sequence:

E_c\&l3a1o8D

Using escape characters

Printer commands always begin with the escape character ( E_c ).

The following table shows how the escape character can be inserted in various MS-DOS programs.

DOS program Entry What appears
Lotus 1-2-3 and Symphony	Type \027	027
Microsoft Word for MS-DOS	Hold down Alt and type 027 on the numeric keypad	↔
WordPerfect for MS-DOS	Type <27>	<27>
MS-DOS Edit	Hold down Ctrl+P, and press Esc	↔
MS-DOS Edlin	Hold down Ctrl+V, and press [	^[
dBase ?? CHR(27)+"command" ?? CHR(27)+" "

Selecting PCL 6 and PCL 5 fonts

The printer font list provides PCL 6 and PCL 5 printer commands for selecting fonts. See PS or PCL font list for information about how to print the list. A sample section is shown in the following illustration.

One variable box is available for specifying symbol sets and one for specifying point size. These variables must be filled in, or the printer will use defaults. For example, if you want a symbol set that contains line-draw characters, select the 10U (PC-8) or 12U (PC-850) symbol set. Other common symbol set codes are listed in the section Common PCL 6 and PCL 5 printer commands.

NOTE

Fonts are either "fixed" or "proportional" in spacing. The printer contains both fixed fonts (Courier, Letter Gothic, and Lineprinter) and proportional fonts (CG Times, Arial, Times New Roman, and others). Fixed-spaced fonts are generally used in programs such as spreadsheets and databases, where it is important for columns to line up vertically. Proportional-spaced fonts are generally used in text and word-processing programs.

Environmental Product Stewardship program

Protecting the environment

Hewlett-Packard Company is committed to providing quality products in an environmentally sound manner. This product has been designed with several attributes to minimize impacts on our environment.

Ozone production

This product generates no appreciable ozone gas ( O_3 ).

Energy consumption

Power usage drops significantly while in PowerSave mode, which saves natural resources and saves money without affecting the high performance of this product. This product qualifies for ENERGY STAR ^® (Printers, Version 3.0), which is a voluntary program to encourage the development of energy-efficient office products.

ENERGY STAR ^® is a U.S. registered service mark owned by the U.S. government. As an ENERGY STAR partner, Hewlett-Packard Company has determined that this product meets ENERGY STAR Guidelines for energy efficiency. For more information, see http://www.energystar.gov.

Toner consumption

EconoMode uses significantly less toner, which might extend the life of the print cartridge.

Paper use

This product's automatic duplex feature (two-sided printing) and n-up printing (multiple pages printed on one page) capabilities can reduce media usage and the resulting demands on natural resources. (The automatic duplex feature is available only for models that include a built-in duplexer. Manual duplexing is available for all models. See Printing on both sides of paper (optional duplexer).)

Plastics

Plastic parts over 25 grams are marked according to international standards that enhance the ability to identify plastics for recycling purposes at the end of the product's life.

HP LaserJet printing supplies

In many countries/regions, this product's printing supplies (for example, print cartridge and fuser) can be returned to HP through the HP Printing Supplies Environmental Program. An easy-to-use and free take back program is available in more than 30 countries/regions. Multilingual program information and instructions are included in every new HP LaserJet print cartridge and supplies package.

HP Printing Supplies Returns and Recycling Program Information

Since 1992, HP has offered HP LaserJet supplies return and recycling free of charge in 86% of the world market where HP LaserJet supplies are sold. Postage-paid and pre-addressed labels are included within the instruction guide in most HP LaserJet print cartridge boxes. Labels and bulk boxes are also available through the Web site at http://www.hp.com/recycle. More than 10 million HP LaserJet print cartridges were recycled globally in 2002 through the HP Planet Partners supplies recycling program. This record number represents 26 million pounds of print cartridge materials that were diverted from landfills. Worldwide, HP recycled an average of 80% of the print cartridge by weight, consisting primarily of plastic and metals. Recycled plastics and metals are used to make new products, such as HP products, plastic trays, and spools. The remaining materials are disposed of in an environmentally responsible manner.

• U.S. returns For a more environmentally responsible return of used cartridges and supplies, HP encourages the use of bulk returns. Simply bundle two or more cartridges together and use the single, prepaid, preaddressed UPS label that is supplied in the package. For more information in the U.S., call 1-800-340-2445 or visit the HP LaserJet Supplies Web site at http://www.hp.com/recycle.

Country-/region-specific safety statements

Laser safety statement

The Center for Devices and Radiological Health (CDRH) of the U.S. Food and Drug Administration has implemented regulations for laser products manufactured since August 1, 1976. Compliance is mandatory for products marketed in the United States. The printer is certified as a "Class 1" laser product under the U.S. Department of Health and Human Services (DHHS) Radiation Performance Standard according to the Radiation Control for Health and Safety Act of 1968.

Since radiation emitted inside the printer is completely confined within protective housings and external covers, the laser beam cannot escape during any phase of normal user operation.

WARNING!

Using controls, making adjustments, or performing procedures other than those specified in this user guide may result in exposure to hazardous radiation.

Canadian DOC statement

DURATION OF LIMITED WARRANTY

One-year limited warranty

HP warrants to you, the end-user customer, that HP hardware and accessories will be free from defects in materials and workmanship after the date of purchase, for the period specified above. If HP receives notice of such defects during the warranty period, HP will, at its option, either repair or replace products which prove to be defective. Replacement products may be either new or equivalent in performance to new.

HP warrants to you that HP software will not fail to execute its programming instructions after the date of purchase, for the period specified above, due to defects in material and workmanship when properly installed and used. If HP receives notice of such defects during the warranty period, HP will replace software which does not execute its programming instructions due to such defects.

HP does not warrant that the operation of HP products will be uninterrupted or error free. If HP is unable, within a reasonable time, to repair or replace any product to a condition as warranted, you will be entitled to a refund of the purchase price upon prompt return of the product.

HP products may contain remanufactured parts equivalent to new in performance or may have been subject to incidental use.

Warranty does not apply to defects resulting from (a) improper or inadequate maintenance or calibration, (b) software, interfacing, parts or supplies not supplied by HP, (c) unauthorized modification or misuse, (d) operation outside of the published environmental specifications for the product, or (e) improper site preparation or maintenance.

TO THE EXTENT ALLOWED BY LOCAL LAW, THE ABOVE WARRANTIES ARE EXCLUSIVE AND NO OTHER WARRANTY OR CONDITION, WHETHER WRITTEN OR ORAL, IS EXPRESSED OR IMPLIED AND HP SPECIFICALLY DISCLAIMS ANY IMPLIED WARRANTIES OR CONDITIONS OF MERCHANTABILITY, SATISFACTORY QUALITY, AND FITNESS FOR A PARTICULAR PURPOSE. Some countries/regions, states or provinces do not allow limitations on the duration of an implied warranty, so the above limitation or exclusion might not apply to you. This warranty gives you specific legal rights and you might also have other rights that vary from country/region to country/region, state to state, or province to province. HP's limited warranty is valid in any country/region or locality where HP has a support presence for this product and where HP has marketed this product. The level of warranty service you receive may vary according to local standards. HP will not alter form, fit or function of the product to make it operate in a country/region for which it was never intended to function for legal or regulatory reasons.

EXCEPT AS INDICATED ABOVE, IN NO EVENT WILL HP OR ITS SUPPLIERS BE LIABLE FOR LOSS OF DATA OR FOR DIRECT, SPECIAL, INCIDENTAL, CONSEQUENTIAL (INCLUDING LOST PROFIT OR DATA), OR OTHER DAMAGE, WHETHER BASED IN CONTRACT, TORT, OR OTHERWISE. Some countries/regions, states or provinces do not allow the exclusion or limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you.

THE WARRANTY TERMS CONTAINED IN THIS STATEMENT, EXCEPT TO THE EXTENT LAWFULLY PERMITTED, DO NOT EXCLUDE, RESTRICT OR MODIFY AND ARE IN ADDITION TO THE MANDATORY STATUTORY RIGHTS APPLICABLE TO THE SALE OF THIS PRODUCT TO YOU.

Print Cartridge Limited Warranty Statement

This HP Print Cartridge is warranted to be free from defects in materials and workmanship.

This warranty does not apply to print cartridges that (a) have been refilled, refurbished, remanufactured or tampered with in any way, (b) experience problems resulting from misuse, improper storage, or operation outside of the published environmental specifications for the printer product or (c) exhibit wear from ordinary use.

Availability of support and service

Around the world, HP provides a variety of service and support options for purchase. Availability of these programs will vary depending upon your location.

HP maintenance agreements

HP has several types of maintenance agreements that meet a wide range of support needs. Maintenance agreements are not part of the standard warranty. Support services vary by location. Contact HP Customer Care to determine the services available to you and for more information about maintenance agreements. In general, the printer will have the following maintenance agreements:

Onsite service agreements

To provide you with the level of support best suited to your needs, HP has on-site service agreements with two response times:

Priority Onsite Service

This agreement provides 4-hour service response to your site for calls made during normal HP business hours.

Next-Day Onsite Service

This agreement provides support by the next working day following a service request. Extended coverage hours and extended travel beyond HP's designated service zones are available on most on-site agreements (for additional charges).

HP Express Exchange (U.S. and Canada only)

This service, available for an additional fee, is an alternative to the standard warranty and entails returning your printer for repair. HP Express Exchange allows you to receive a refurbished replacement unit and then return your defective printer. The fast turnaround from HP Express Exchange minimizes downtime over traditional service programs that require you to ship the defective printer to the manufacturer and then wait for the printer to be repaired and returned.

If you choose to use this service, follow the steps listed below. If you have HP on-site support service, you should work directly with the local HP Customer Care center instead of following the steps outlined here.

NOTE

To identify potential support options for this printer, go to http://www.hpexpress-services.com and type the printer model number. In North America, additional options might be available through HP Customer Care. Call 1-800-HPINVENT [1-800-474-6836 (U.S.)] or 1-800-268-1221 (Canada).

To use HP Express Exchange

1. Call the HP Customer Care Center for the U.S. or Canada. A technician troubleshoots the situation and determines whether the printer has actually failed. If so, the technician refers the customer to the HP Service Center.
2. A representative from the service center requests product and customer information. In some cases, collateral might also be requested.
3. Before agreeing to use this service, check with the representative for information about returning your defective printer.
4. HP ships a refurbished replacement unit to arrive the next day. (Geographic distance might prevent next-day shipping.)

Exchanged units carry the remainder of the original unit's warranty or 90 days, whichever is greater.

Repacking the printer

If HP Customer Care determines that your printer needs to be returned to HP for repair, follow the steps below to repack the printer before shipping it.

CAUTION

Shipping damage as a result of inadequate packing is the customer's responsibility.

To repack the printer

1. Remove and retain any DIMMs or CompactFlash cards that you have purchased and installed in the printer. Do not remove the DIMM that came with the printer.

CAUTION

Static electricity can damage DIMMs. When handling DIMMs, either wear an antistatic wrist strap, or frequently touch the surface of the DIMM antistatic package and then touch bare metal on the printer. To remove the DIMMs, see Printer memory.

1. Remove and retain the print cartridge.

CAUTION

It is extremely important to remove the print cartridge before shipping the printer. A print cartridge that is left in the printer during shipping will leak and entirely cover the printer engine and other parts with toner.

To prevent damage to the print cartridge, avoid touching the roller on it, and store the print cartridge in its original packing material or so that it is not exposed to light.

1. Remove and retain the power cable, interface cable, and optional accessories.

2. If possible, include print samples and 50 to 100 sheets of paper or other print media that did not print correctly.

3. Include a completed copy of the Service information form.

4. In the U.S., call HP Customer Care to request new packing material. In other areas, use the original packing material, if possible. Hewlett-Packard recommends insuring the equipment for shipment.
