Utilities

The HP Color LaserJet 5550 series printer is equipped with several utilities, which make it easy to monitor and manage the printer on a network.

Embedded Web server

This printer is equipped with an embedded Web server, which allows access to information about printer and network activities. A Web server provides an environment in which web programs may run, much in the same way that an operating system, such as Windows, provides an environment for programs to run on your computer. The output from these programs can then be displayed by a Web browser, such as Microsoft Internet Explorer or Netscape Navigator.

When a Web server is "embedded", that means it resides on a hardware device (such as a printer) or in firmware, rather than as software that is loaded on a network server.

The advantage of an embedded Web server is that it provides an interface to the printer that anyone can access with a network-connected computer or a standard Web browser. There is no special software to install or configure. For more information about the HP embedded Web server, see the Embedded Web Server User Guide. You can find this guide on the CD-ROM included with the printer.

Features

The HP embedded Web server allows you to view printer and network card status and manage printing functions from your computer. With the HP embedded Web server, you can do the following:

• view printer status information
• determine the remaining life on 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
• add or customize links to other Web sites
- select the language in which to display the embedded Web server pages
• view and change network configuration

For a complete explanation of the features and functionality of the embedded Web server, see Using the embedded Web server.

hp toolbox

The HP Toolbox is a Windows-only software application that can be used for the following tasks:

• check the printer status
  • view troubleshooting information
  • view online documentation
  • print internal printer pages
  • receive pop-up status messages
• access the embedded Web server

You can view the HP Toolbox when the printer is directly connected to your computer or when it is connected to a network. You must have performed a complete software installation before using the HP Toolbox.

Other components and utilities

Several software applications are available for Windows and Macintosh OS users, as well as for network administrators. These programs are summarized below.

Print media specifications

For optimum results, use conventional 75 g/m^2 to 90 g/m^2 (20 to 24 lb) photocopy paper. Verify that the paper is of good quality and is free of cuts, nicks, tears, spots, loose particles, dust, wrinkles, curls, or bent edges.

• To order supplies worldwide, go to http://www.hp.com/ghp/buyonline.html.
• To order accessories, go to http://www.hp.com/go/accessories.
- For additional information about supported media weights and sizes, go to http://www.hp.com/support/ljpaperguide.

Supported paper weights and sizes

Letter and A4 sizes can be loaded with the long-edge or short-edge leading into the printer. Long-edge first is the preferred orientation. Long-edge feed gives greater throughput, and lower consumable usage. Short-edge feed is called the rotated orientation, and is identified in the trays as LTR-R and A4-R. Short-edge feed can be useful when printing on media with special features, such as perforations or windows.

Enhanced I/O (EIO) configuration

This printer comes equipped with three enhanced input/output (EIO) slots. The three EIO slots hold compatible external devices such as the HP Jetdirect print server network cards, HP EIO hard drive, or other devices. Plugging EIO network cards into the slots increases the number of network interfaces available to the printer.

EIO network cards can maximize printer performance when you are printing from a network. In addition they provide the ability to place the printer anywhere on a network. This eliminates the need to attach the printer directly to a server or a workstation and enables you to place the printer closer to the network users.

If the printer is configured through an EIO network card, configure that card through the control panel Configure device menu.

HP Jetdirect print servers

HP Jetdirect print servers (network cards) can be installed in one of the printer's EIO slots. These cards support multiple network protocols and operating systems. HP Jetdirect print servers facilitate network management by allowing you to connect a printer directly to your network at any location. HP Jetdirect print servers also support the Simple Network Management Protocol (SNMP), which provides network managers with remote printer management and troubleshooting through HP Web Jetadmin software.

Note

Installation of these cards and network configuration should be performed by a network administrator. Configure the card either through the control panel, the printer installation software, or with HP Web Jetadmin software.

Note

Refer to the HP Jetdirect print server documentation for information on which external devices or EIO network cards are supported.

Printing tasks

This chapter describes how to perform basic printing tasks. The following topics are covered:

• Controlling print jobs
- Selecting print media
- Configuring input trays
- Printing on special media
- Two-sided (duplex) printing
• Special printing situations
Job storage features
Managing memory

Controlling print jobs

Three settings affect the printer driver's ability to specify how paper should be pulled in the printer. The Source, Type, and Size settings appear in the Page Setup, Print, or Print Properties dialog boxes in most software programs. If you do not change these settings, the printer automatically selects a tray using the default printer settings.

Source

Printing by Source means you choose a specific tray from which you want the printer to pull paper. The printer tries to print from this tray, no matter what type or size is loaded in it. If you choose a tray that is configured for a type or size that does not match your print job, the printer does not print automatically. Instead, it waits for you to load the tray you chose with the type or size of print paper for your print job. If you load the tray correctly, the printer begins printing. If you press √, the display allows you to choose from other loaded trays.

Note

If you have difficulties printing by Source and want the printer to autoswitch from the specified tray, see Tray behavior options: Use Requested Tray and manually feed.

Type and Size

Printing by Type or Size means you want the printer to pull paper or print paper from the first tray that is loaded with the type or size that you choose. Selecting paper by Type rather than Source is similar to locking out trays and helps protect special paper from accidental use. (However, selecting the Any setting does not enable this tray lockout function.) For example, if a tray is configured for letterhead, and you specify the driver to print on plain paper, the printer will not pull the letterhead from that tray. Instead, it will pull paper from a tray that has plain paper loaded and is configured for plain paper on the printer control panel. Selecting paper by Type and Size results in significantly better print quality for heavy paper, glossy paper, and transparencies. Using the wrong setting can result in unsatisfactory print quality. Always print by Type for special print media such as labels or grayscale transparencies. Always print by Size for envelopes.

• If you want to print by Type or Size and the trays have not been configured for that type or size, in the printer driver, select the Type or Size from the Page Setup dialog box, the Print dialog box, or the Print Properties dialog box. The printer will prompt you to load that type and size.
• If you often print on a certain type or size of paper, the printer administrator (for a network printer) or you (for a local printer) can configure a tray for that type or size (see Using the embedded Web server or Configuring input trays for type and size). Then, when you choose that type or size as you print a job, the printer pulls from the tray configured for that type or size.

Print setting priorities

Changes made to print settings are prioritized (or take precedence) depending on where the changes are made:

Note

The names of commands and dialog boxes may vary depending on your program.

• Page Setup dialog box. This dialog box opens when you click Page Setup or a similar command on the File menu of the program you are working in. Settings changed here override settings changed anywhere else.
• Print dialog box. This dialog box opens when you click Print, Print Setup, or a similar command on the File menu of the program you are working in. Settings changed in the Print dialog box have a lower priority and do not override changes made in the Page Setup dialog box.
• Printer Properties dialog box (printer driver). The printer driver opens when you click Properties in the Print dialog box. Settings changed in the Printer Properties dialog box do not override settings available anywhere else.
• Printer menu settings. Lowest priority and often used if software drivers do not have that option.
• Default printer settings. The default printer driver settings determine settings used in all print jobs, unless settings are changed in the Page Setup, Print, or Printer Properties dialog boxes, as described above. There are several ways to change the default printer settings depending on the operating system: 1) click Start, Settings, Printers, and then right-click the printer icon and click Properties; 2) click Start, Control Panel, and then select the Printers folder; right-click the printer icon and click Properties.

CAUTION

To avoid affecting print jobs of other users, make printer setup changes through the software application or the printer driver whenever possible. Printer setup changes made through the control panel become default settings for subsequent jobs. Changes made through an application or the printer driver affect only that specific job.

Selecting print media

You can use many types of paper and other print media with this printer. This section provides guidelines and specifications for selecting and using different print media.

Before purchasing any paper or specialized forms in quantity, verify that your paper supplier obtains and understands the print media requirements specified in the HP LaserJet Printer Family Print Media Guide.

See Supplies and accessories for HP LaserJet Printer Family Print Media Guide ordering information. To download a copy of the HP LaserJet Printer Family Print Media Guide go to http://www.hp.com/support/clj5550 and select Manuals.

It is possible that paper could meet all of the guidelines in this chapter and still not print satisfactorily. This may be due to abnormal characteristics of the printing environment or to other variables over which Hewlett-Packard has no control (for example, extremes in temperature and humidity).

Hewlett-Packard recommends testing any paper before buying it in large quantities.

CAUTION

Using paper that does not conform to the specifications listed here or in the print media guide can cause problems that require service. This service is not covered by the Hewlett-Packard warranty or service agreements.

Media to avoid

The HP Color LaserJet 5550 series printer can handle many types of paper. Use of paper outside the printer's specifications will cause a loss of print quality and increase the chance of paper jams occurring.

• Do not use paper that is too rough.
• Do not use paper with cutouts or perforations other than standard 3-hole punched paper.
  • Do not use multipart forms.
• Do not use paper that has already been printed on or that has been fed through a photocopier.
• Do not use paper with a watermark if you are printing solid patterns.

Media that may damage the printer

In rare circumstances paper can damage the printer. The following paper must be avoided to prevent possible damage:

• Do not use paper with staples attached.
• Do not use transparencies designed for Inkjet printers or other low temperature printers. Use only transparencies that are specified for use with HP Color LaserJet printers.
• Do not use photo paper intended for Inkjet printers.

• Do not use paper that is embossed or coated and is not designed for the temperatures of the HP Color LaserJet 5550 image fuser. Select paper that can tolerate temperatures of 190^ (374°F) for 0.1 second. HP produces a selection of paper that is designed for the HP Color LaserJet 5550 series printer.

• Do not use letterhead paper with low temperature dyes or thermography. Preprinted forms or letterhead must use inks that can tolerate temperatures of 190°C (374°F) for 0.1 second.

• Do not use any media that produces hazardous emissions, or that melts, offsets, or discolors when exposed to 190^ (374°F) for 0.1 second.

To order HP Color LaserJet printing supplies, go to http://www.hp.com/go/ljsupplies in the U.S. or to http://www.hp.com/ghp/buyonline.html worldwide.

Configuring input trays

The HP Color LaserJet 5550 series printer allows you to configure input trays by type and size. You can load different paper in the printer input trays and then request paper by type or size.

Note

If you have used previous HP Color LaserJet printers, you might be accustomed to configuring Tray 1 to first mode or cassette mode. To mimic the settings for first mode, configure Tray 1 for Size = ANY and Type = ANY. The printer will pull paper from Tray 1 first when the print job does not specify another tray. This setting is recommended if you use different types or sizes of paper. To mimic the settings from cassette mode, set either the size or type for Tray 1 to a setting other than ANY. This setting is recommended if you are using the same size and type of paper in Tray 1.

Note

If you use two-sided printing (duplex), be sure that the paper loaded meets the specifications for duplex printing. (See Supported paper weights and sizes.)

The instructions below are to configure the trays at the printer control panel. You can also configure the trays from your computer by accessing the embedded Web server. See Using the embedded Web server.

Note

Letter and A4 sizes can be loaded with the long-edge or short-edge leading into the printer. Long-edge first is the preferred orientation. Long-edge feed gives greater throughput, and lower consumable usage. Short-edge feed is called the rotated orientation, and is identified in the trays as LTR-R and A4-R. Short-edge feed can be useful when printing on media with special features, such as perforations or windows.

Configuring trays when the printer gives a prompt

In the following situations, the printer automatically prompts you to configure the tray for type and size:

• when you load paper into the tray, on tray close you will see Tray X . To change the type or size, press √.
• when you specify a particular tray or media type for a print job through the printer driver or a software application and the tray is not configured to match the print job's settings. You will see LOAD TRAY X .

The control panel displays this message: LOAD TRAY X , to change size or type, press √. The instructions below explain how to configure the tray after the prompt appears.

Note

The prompt does not appear if you are printing from Tray 1 and if Tray 1 is configured for ANY SIZE and ANY TYPE.

Printing on special media

Use these guidelines when printing on special types of media.

Note

Special media such as envelopes or cardstock should be printed from Tray 1.

To print on any special media, use the following procedure:

1. Load the media in the paper tray.
2. When the printer prompts you for the paper type, select the correct media type for the paper loaded in the tray. For example, select HIGH GLOSS IMAGES when loading HP High Gloss Laser Paper
3. In the software application or the printer driver, set the media type to match the media type that is loaded in the paper tray.

Note

For the best print quality, always verify that the media type selected on the printer control panel and the media type selected in the application or printer driver match the type of media loaded in the tray.

Transparencies

When printing on transparencies, use the following guidelines:

• Handle transparencies using the edges. Oils from your fingers deposited on the transparency can cause print quality problems.
• Use only overhead transparencies recommended for use in this printer. Hewlett-Packard recommends using HP Color LaserJet Transparencies with this printer. HP products are designed to work together for optimum printing results.
• In either the software application or the driver, select Transparency as the media type, or print from a tray that is configured for transparencies. Use the control panel to set the media type.
  For more information about how to access the printer drivers, see Accessing the printer drivers.

CAUTION

Transparencies not designed for LaserJet printing will melt in the printer, causing damage to the printer.

Glossy paper

• In either the software application or the driver, select Glossy, Heavy Glossy, or High Gloss as the media type, or print from a tray that is configured for glossy paper.
  Select Glossy for media weights up to 105 g/m^2 (28 lb bond). Select Heavy glossy for media weights of 105 g/m^2 (28 lb bond) and heavier.
• Use the control panel to set the media type to GLOSSY or HEAVY GLOSSY for the input tray being used.

Note

Hewlett-Packard recommends using HP Color LaserJet Soft Gloss paper with this printer. HP products are designed to work together for optimum printing results. If HP Color LaserJet Soft Gloss paper is not used with this printer, print quality may be compromised.

Colored paper

• Colored paper should be of the same high quality as white xerographic paper.
• Pigments used must be able to withstand the printer fusing temperature of 190°C (374°F) for 0.1 second without deterioration.
• Do not use paper with a colored coating that was added after the paper was produced.
• The printer creates colors by printing patterns of dots, overlaying and varying their spacing to produce various colors. Varying the shade or color of the paper will affect the shades of the printed colors.

Printing images

To obtain the best print quality when printing images, such as photographs or posters, use High Gloss Laser Paper (Q2420A) with the HP High Gloss (Images) media type setting.

• In either the software application or the printer driver, select HP High Gloss (images) as the media type, or print from a tray that is configured for glossy paper.
• You can also configure the printer using settings on the printer control panel. See Configuring input trays for more information.
• Use the control panel to set the media type to HIGH GLOSS IMAGES for the tray being used.

Envelopes

Note

Envelopes can be printed only from Tray 1. Set the tray's media size to the specific envelope size. See Printing envelopes from Tray 1.

Adhering to the following guidelines will help ensure proper printing on envelopes and help prevent printer jams:

• Do not load more than 20 envelopes into Tray 1.
  • The weight rating of envelopes should not exceed 105 g/m^2 (28 lb bond).
  • Envelopes should be flat.
• Do not use envelopes with windows or clasps.
• Envelopes must not be wrinkled, nicked, or otherwise damaged.
• Envelopes with peel-off adhesive strips must use adhesives that can withstand the heat and pressures of the printer's fusing process.
• Envelopes should be loaded face-down with the top of the envelope to the left, and the short edge feeding into the printer first.

Note

In high humidity environments, envelopes should be printed with the flap on the leading edge to reduce sealing of the flap during printing. For long edge printing, envelopes should be loaded long edge first, face-down. See Printing envelopes from Tray 1 to change the envelope orientation.

Labels

Note

For printing labels, set the tray's media type to LABELS in the printer control panel. See Configuring input trays. When printing labels, use the following guidelines:

• Verify that the labels' adhesive material can tolerate temperatures of 190^ (374°F) for 0.1 second.
• Verify that there is no exposed adhesive material between the labels. Exposed areas can cause labels to peel off during printing, which can cause printer jams. Exposed adhesive can also cause damage to printer components.
  • Do not re-feed a sheet of labels.
• Verify that labels lie flat.
• Do not use labels that are wrinkled, bubbled, or otherwise damaged.

Heavy paper

The following heavy paper types can be used with the HP Color LaserJet 5550 series printer.

Paper type Paper weight
Heavy	105-119 g/m228-31 lb
Extra heavy	120-163 g/m232-43 lb
Cardstock	164-200 g/m244-53 lb

When printing on heavy paper types, use the following guidelines:

• Use Tray 1 for paper that is heavier than 163g / m^2 to 200g / m^2 (43 lb bond up to 53 lb bond).
• For optimum results when printing on heavy paper, use the printer control panel to set the media type for the tray to match the paper type.
• In either the software application or the driver, select Heavy, Extra Heavy, or Cardstock as the media type, or print from a tray that is configured for heavy paper.
• Because this setting affects all print jobs, it is important to return the printer back to its original settings once the job has printed. See Configuring input trays.

CAUTION

In general do not use paper that is heavier than the media specification recommended for this printer. Doing so can cause misfeeds, paper jams, reduced print quality, and excessive mechanical wear.

HP LaserJet Tough paper

Tough paper is a robust plastic film that will not tear and withstands the weather. When printing on HP LaserJet Tough paper, use the following guidelines:

• Handle HP LaserJet Tough paper using the edges. Oils from your fingers deposited on HP LaserJet Tough paper can cause print quality problems.
• Use only Hewlett-Packard LaserJet Tough paper with this printer. HP Products are designed to work together for optimum printing results.
• In either the software application or the driver, select Tough Paper as the media type, or print from a tray that is configured for HP LaserJet Tough paper.

Preprinted forms and letterhead

Observe the following guidelines for best results with preprinted forms and letterhead:

• Forms and letterhead must be printed with heat-resistant inks that will not melt, vaporize, or release hazardous emissions when subjected to the printer's fusing temperature of approximately 190°C (374°F) for 0.1 second.
• Inks must be non-flammable and should not adversely affect any printer rollers.
• Forms and letterhead should be sealed in a moisture-proof wrapping to prevent changes during storage.
• Before loading preprinted paper such as forms and letterhead, verify that the ink on the paper is dry. During the fusing process, wet ink can come off of preprinted paper.
• When duplex printing, load pre-printed forms and letterhead into Trays 2, 3, 4, and 5 face-down with the top edge of the page to the left. To load pre-printed forms and letterhead into Tray 1, load them face-up with the top edge of the page to the left.
• When simplex printing, load pre-printed forms and letterhead into Trays 2, 3, 4, and 5 face-up with the top edge of the page to the left. To load pre-printed forms and letterhead into Tray 1, load them face-down with the top edge of the page to the left.

Recycled paper

This printer supports the use of recycled paper. Recycled paper must meet the same specifications as standard paper. See the HP LaserJet Printer Family Print Media Guide. Hewlett-Packard recommends that recycled paper contain no more than 5% ground wood.

Two-sided (duplex) printing

Some printer models are capable of automatic duplex printing (printing on both sides of a page). To find out which models support automatic two-sided printing, see Printer configurations. All printer models support manual two-sided printing.

Note

You must specify two-sided printing options in your software application or in the printer driver in order to print on both sides of the page. If this option is not visible in the software application or printer driver, use the following information to make duplex printing options available.

To use two-sided printing:

• Verify that the printer driver is configured to show the two-sided printing options: automatic and/or manual. For instructions, see the online Help for the printer driver or for more information about how to access the printer drivers, see Accessing the printer drivers.
• Once the two-sided printing option is shown, select the appropriate two-sided printing options in the printer driver software. Two-sided printing options include page and binding orientation. For more information about options for binding two-sided printing jobs, see Options for binding two-sided printing jobs.
  • Automatic two-sided printing is not supported for certain media types, including transparencies, envelopes, cardstock, tough paper and labels.
• Automatic two-sided printing only supports 11 x 17, A3, letter, letter_R, legal, A4, A4-R, B5, B4, and executive paper sizes.
• Manual two-sided printing can support all sizes and more types of media. (Transparencies, envelopes, and labels are not supported.)

• If both automatic and manual two-sided printing are enabled in the software driver, the printer will automatically print on two sides if the size and type are supported by the duplexer. Otherwise, it will manually duplex.

• For best results, avoid two-sided printing with rough-textured, heavy-weight media.

• When duplexing preprinted media such as letterhead or forms, load the paper the opposite of that when duplexing simplex. Place the media face down in Trays 2, 3, 4, or 5. Place special media face up in Tray 1. (This process is different than the process for one-sided printing.)

Control panel settings for automatic two-sided printing

Many software applications allow you to change two-sided printing settings. If your software application or printer driver does not allow you to adjust two-sided printing settings, you can adjust these settings through the control panel. The factory default setting is OFF.

CAUTION

Do not use two-sided printing when printing on labels. Serious damage to the printer may result.

Note

To enable or disable two-sided printing from the printer control panel

Changing settings for two-sided printing through the printer control panel affects all print jobs. Whenever possible, change settings for two-sided printing through your software application or printer driver.

Duplexing blank pages

If selecting source or type in the software driver, the printer will not print blank second sides of duplexed pages, resulting in faster performance. However, if the paper type is set to ANY TYPE, LETTERHEAD, PREPRINTED, or PREPUNCHED, the blank second sides print to prevent text from printing on the wrong side of the page.

Options for binding two-sided printing jobs

Before printing a two-sided document, in the printer driver choose the edge on which you will bind your finished document. Long-edge or book binding is the conventional layout used in book binding. Short-edge or tablet binding is the typical calendar binding.

Note

The default binding setting is to bind on the long edge when the page is set up for portrait orientation. To change to short edge binding, click the Flip Pages Up check box.

Manual two-sided (duplex) printing

Printing on both sides can be performed manually (manual duplex printing). This is useful for paper sizes or weights that are not supported for automatic duplexing (for example, cardstock or custom size paper). It can also be performed on printer models that do not support automatic two-sided printing.

Note

Damaged or previously used paper can cause paper jams and should not be used.

Note

Manual two-sided printing is not supported for Windows 98 and NT 4.0 systems that use the PS driver.

To manually print on two sides (duplex)

1. Ensure that the printer driver is configured to allow manual duplexing. In the printer driver, select Allow Manual Duplex. See Accessing the printer drivers.
2. From the application, open the printer driver.
3. Select the appropriate size and type.
4. On the Finishing tab, click Print on Both Sides or Print on Both Sides (Manually).
5. The default binding option is to bind on the long edge of the paper in portrait layout. To change the setting, click the Finishing tab, and select the Flip pages up checkbox.
6. Click OK. The Print on Both Sides instructions will appear. Follow the instructions to finish printing your document.

If total sheets exceed the Tray 1 capacity for manual duplex jobs, feed the top 100 sheets and press √. When prompted, feed the next 100 sheets and press √ Repeat as necessary until all the sheets from the output stack have been loaded into Tray 1.

For more information about how to access the printer drivers, see Accessing the printer drivers.

Printing booklets

Some versions of the printer driver let you control the printing of booklets when duplexing. You can select binding on the left or right side on letter, legal, or A4 paper size. Windows 2000 and XP supports booklet printing for all paper sizes.

See the printer driver online Help for more information about the printing booklets feature.

Adjusting the registration

Adjusting the registration ensures that all jobs are centered on the page. This is a two-part process: 1) estimating the centering adjustments and 2) setting the shift values.

Use the following procedure to estimate the centering adjustments.

1. Using a ruler, measure, in millimeters, the left and right margins on the front side of the printed test page. Compare the two measurements.
2. Estimate the adjustment necessary to center the page. Each unit of adjustment shifts the image approximately 0.25 mm. This is the X1 shift value.
3. Using a ruler, measure, in millimeters, the left and right margins on the back side of the printed test page. Compare the two measurements.
4. Estimate the adjustment necessary to center the page. Each unit of adjustment shifts the image approximately 0.25 mm. This is the X2 shift value.
5. Using a ruler, measure, in millimeters, the top and bottom margins on the printed test page. Compare the two measurements.
6. Estimate the adjustment necessary to center the page. Each unit of adjustment shifts the image approximately 0.25 mm. This is the Y shift value.

Use the following procedure to set the shift values.

Special printing situations

Use these guidelines when printing on special types of paper.

Printing a different first page

Use the following procedure to print the first page of a document on a different paper type than the rest of the document, for example, to print the first page of a document on letterhead paper and the rest on plain paper.

1. From your application or printer driver, specify a tray for the first page and another tray for the remaining pages.
   For more information about how to access the printer drivers, see Accessing the printer drivers.
2. Load the special paper into the tray that you specified in step 1.
3. Load the paper for the remaining pages of the document into another tray.

You can also print on different paper by using the printer control panel or printer driver to set the types of paper that are loaded in the trays and then selecting the first and remaining pages by paper type.

Printing a blank back cover

Use the following procedure to print a blank back cover. You can also select an alternate paper source or print on a different media type than the rest of the document.

1. On the printer driver's Paper tab, select Use different paper, then from the drop-down list, select Back Cover, check Add a blank back cover, and then click OK.
2. For more information about how to access the printer drivers, see Accessing the printer drivers.

You can also select an alternate paper source or print a blank back cover on a different media type than the rest of the document. If desired, select a different source and type from the drop-down lists.

Printing on custom-size media

The printer supports single-sided printing and manual duplexing on custom-size paper. Tray 1 supports paper sizes from 76 x 127 mm (3 x 5 inches) to 312 x 470 mm (12.3 x 18.5 inches). Tray 2 and optional Trays 3, 4 and 5 support media sizes from 148 x 210 mm (7.16 x 8.27 inches) to 297 x 432 mm (8.5 x 14 inches).

When printing on custom-size paper, if Tray 1 is configured in the printer control panel as TRAY 1 TYPE=ANY and TRAY 1 SIZE=ANY, the printer will print on whatever paper is loaded in the tray. When printing on custom size paper from Trays 2, 3, 4, and 5, adjust the switch on the tray to the Custom position, and from the control panel, set the paper size to CUSTOM or ANY CUSTOM.

Some software applications and printer drivers allow you to specify custom paper-size dimensions. Be sure to set the correct paper size in both the page setup and print dialog boxes. If your software does not allow this, specify the custom paper-size dimensions in the Paper handling menu of the printer control panel. See Paper handling menu for more information.

Note

The printer feeder supports up to 312 mm wide, but the printer driver is limited to 304 mm.

For more information about how to access the printer drivers, see Accessing the printer drivers.

If your software application requires you to calculate margins for custom-size paper, see the online Help for that application.

Stopping a print request

You can stop a print request either from the printer control panel or from your software application. To stop a print request from a computer on a network, see the online Help for the specific network software.

Note

It may take some time for all printing to clear after you have canceled a print job.

Job storage features

The HP Color LaserJet 5550 series printer lets you store a job in the printer's memory for printing at a later time. The job storage features use memory from both the hard drive and random access memory (RAM). These job storage features are described below.

To support job storage features for complex jobs, or if you often print complex graphics, print PostScript (PS) documents, or use many downloaded fonts, HP recommends that you install additional memory. Added memory also gives you more flexibility in supporting job-storage features, such as quick copying.

Note

To use the Private Job and Proof and Hold features, you must have a minimum of 192 MB of memory: 160 MB DDR plus 32 MB of additional memory on the formatter board. To use the quick copy and stored jobs features you must install an optional hard drive in the printer (HP Color LaserJet 5550, 5550n, 5550dn, 5550dtn models) and properly configure the drivers.

CAUTION

Make sure to uniquely identify jobs in the printer driver before printing. Using default names may override previous jobs with the same default name or cause the job to be deleted. For more information about how to access the printer drivers, see Accessing the printer drivers.

Storing a print job

You can download a print job to the printer without printing it. You can then print the job at any time through the printer control panel. For example, you may want to download a personnel form, calendar, time sheet, or accounting form that other users can access and print.

Private jobs

This option allows you to send a print job directly to the printer memory. Selection of Private Job activates the PIN field. The print job can be printed only after you type a PIN in the printer control panel. After the job is printed, the printer removes the job from the printer memory. This feature is useful when you are printing sensitive or confidential documents that you do not want to leave in an output bin after printing. Private Job stores the print job on the hard drive or in printer RAM memory. After it is released for printing, the private job is immediately deleted from the printer. If more copies are needed, you have to reprint the job from the program. If you send a second private job to the printer with the same user name and job name as an existing private job (and you have not released the original job for printing), the job will overwrite the existing job, regardless of the PIN. Private jobs are deleted if power to the printer is turned off.

Note

A lock symbol next to a job name indicates that the job is private.

Specify that a job is private from the driver. Select the Private Job option and type a 4-digit PIN. To avoid overwriting jobs with the same name, also specify a username and job name.

11. Press √ when finished entering PIN.
12. Press √ to delete the job.

Mopier mode

When Mopier Mode is enabled in the driver, the printer produces multiple, collated copies from a single print job. Multiple-original printing (mopying) increases printer performance and reduces network traffic by sending the job to the printer once, then storing it in the printer's RAM. The remainder of the copies are printed at the printer's fastest speed. All documents can be created, controlled, managed, and finished from the desktop, which eliminates the extra step of using a photocopier.

The HP Color LaserJet 5550 series printers support the mopying feature, provided they have enough total memory (at least 192 MB of total memory: 160 MB DDR plus 32 MB on the formatter board), and the mopying feature is enabled by default if the Mopier Mode setting is Enabled in the Device Settings tab.

Managing memory

This printer supports up to 544 MB of memory: 512 MB DDR plus 32 MB of additional memory on the formatter board. You can add additional memory by installing dual data-rate (DDR) memory. To allow for memory expansion, the printer has two DDR slots, which accept 128 or 256 MB of RAM each. For information about installing memory, see Working with memory and print server cards.

Note

Memory specification: HP Color LaserJet 5550 series printers use 200-pin small outline dual inline memory modules (SODIMM) that support 128 or 256 MB of RAM.

The printer features Memory Enhancement Technology (MEt), which automatically compresses page data to provide the most efficient use of the printer's RAM.

The printer uses DDR SODIMM. Extended data output (EDO) DIMMs are not supported.

Note

If memory problems occur when you are printing complex graphics, you can make more memory available by removing downloaded fonts, style sheets, and macros from printer memory. Reducing the complexity of a print job from within an application can help avoid memory problems.

Color

This chapter describes how the HP Color LaserJet 5550 series printer provides great color printing. This chapter also describes ways to produce the best possible color prints. The following topics are covered:

Using color
• Managing printer color options
- Matching colors

Using color

The HP Color LaserJet 5550 series printer offers great color printing as soon as you set up the printer. It provides a combination of automatic color features to generate excellent color results for the general office user, plus sophisticated tools for the professional who is experienced with color use.

The HP Color LaserJet 5550 series printer provides carefully designed and tested color tables to provide smooth, accurate color rendition of all printable colors.

Paper selection

For the best color and image quality it is important to select the appropriate paper type from the software printer menu or from the front panel. See Selecting print media.

HP ImageREt 3600

HP ImageREt 3600 print technology is a system of innovative technologies developed exclusively by HP to deliver superior print quality. The HP ImageREt system sets itself apart from the industry by integrating technology advancements and optimizing each element of the print system. Several categories of HP ImageREt have been developed for a variety of user needs.

The system's foundation is comprised of key color laser technologies, including image enhancements, smart supplies, and high-resolution imaging. As the level or category of ImageREt increases, these core technologies are refined for more advanced system usage, and additional technologies are integrated. The HP ImageREt 3600 is a complete HP proprietary printing solution developed and implemented for the HP Color LaserJet 5550 series printer. HP now offers superior image enhancements for general office documents and marketing collateral. HP Image REt 3600 does well in different environmental conditions and with a variety of media. The image mode of this print system is optimized for printing on HP High Gloss Laser Paper.

Best image printing

For the best image quality from the HP Color LaserJet 5550 series printer, use HP High Gloss Laser Paper in the special imaging mode. To select the image mode, set the media type to HP High Gloss (Images). See Printing on special media for more information.

Color options

Color options enable optimal color output automatically for diverse types of documents.

Color options use object tagging, which allows optimal color and halftone settings to be used for different objects (text, graphics, and photos) on a page. The printer driver determines which objects are used on a page and uses halftone and color settings that provide the best print quality for each object. Object tagging, combined with optimized default settings, produces great color out of the box.

In the Windows environment, the Automatic and Manual color options are on the Color tab in the printer driver.

For more information about accessing the printer drivers, see Accessing the printer drivers.

sRGB

Standard red-green-blue (sRGB) is a world-wide color standard originally developed by HP and Microsoft as a common color language for monitors, input devices (scanners, digital cameras), and output devices (printers, plotters). It is the default color space used for HP products, Microsoft operating systems, the World Wide Web, and most office software sold today. sRGB is representative of the typical Windows PC monitor today and the convergence standard for high-definition television.

Note

Factors such as the type of monitor you use and the room lighting can affect the appearance of colors on your screen. For more information, see Matching colors.

The latest versions of Adobe PhotoShop, CorelDRAW™, Microsoft Office, and many other applications use sRGB to communicate color. Most importantly, as the default color space in Microsoft operating systems, sRGB has gained broad adoption as a means to exchange color information between applications and devices using a common definition that assures typical users will experience greatly improved color matching. sRGB improves your ability to match colors between the printer, the PC monitor and other input devices (scanner, digital camera) automatically, without the need to become a color expert.

Printing in four-colors (CMYK)

Cyan, magenta, yellow, and black (CMYK) are the inks used by a printing press. The process is often called four-color printing. CMYK data files are typically used by and originate from graphic arts (printing and publishing) environments. The printer will accept CMYK colors through the PS printer driver. The printer color-rendering of CMYK is designed to provide rich, saturated colors for text and graphics.

CMYK ink set emulation (PostScript only)

The printer's color rendering of CMYK can be made to emulate several standard Offset Press ink sets.

• Default. This selection is good for general purpose rendering of CMYK data. It is designed to render photographs well, while at the same time providing rich saturated colors for text and graphics.
• Specification for Web Offset Publications (SWOP). Common ink standards in the United States and other locations.
  • Euroscale. Common ink standard in Europe and other locations.
  • Dainippon Ink and Chemical (DIC). Common ink standard in Japan and other locations.
• Device. Emulation is turned off. To render photographs properly with this selection, images require color management in the application or operating system.

Managing printer color options

Setting color options to Automatic will typically produce the best possible print quality for color documents. However, there may be cases when you want to print a color document in grayscale (black and white) or wish to change one of the printer's color options.

• Using Windows, print in grayscale or change the color options using settings found on the Color tab in the printer driver.
• Using a Macintosh computer, print in grayscale or change the color options using the Color Matching pop-up menu in the Print dialog box.

For more information about accessing the printer drivers, see Accessing the printer drivers.

Print in Grayscale

Selecting the Print in Grayscale option from the printer driver prints a document in black and white. This option is useful for printing color documents that will be photocopied or faxed.

Automatic or manual color adjustment

The Automatic color adjustment option optimizes the neutral gray color treatment, halftones, and edge enhancements used for each element in a document. For more information, see your printer driver online Help.

Note

Automatic is the default setting and is recommended for printing all color documents.

The Manual color adjustment option allows you to adjust the neutral gray color treatment, halftones, and edge enhancements for text, graphics and photographs. To access the Manual color options, from the Color tab, select Manual, then Settings.

Manual color options

Manual color adjustment allows you to adjust the Color (or Color Map) and Halftoning options individually for text, graphics, and photographs.

Note

Some applications convert text or graphics to raster images. In these cases, the Photographs settings will also control text and graphics.

Halftone options. Halftone options affect the resolution and clarity of your color output. You can select halftone settings for text, graphics, and photographs independently. The two halftone options are Smooth and Detail.

• The Smooth option provides better results for large, solid-filled print areas. It also enhances photographs by smoothing out fine color gradations. Choose this option when uniform and smooth area fills are top priority.
• The Detail option is useful for text and graphics that require sharp distinctions among lines or colors, or images that contain a pattern or a high level of detail. Choose this option when sharp edges and details are top priority.

Neutral Grays. The Neutral Grays setting determines the method used for creating gray colors used in text, graphics, and photographs.

Two values are available for the Neutral Grays setting:

• Black Only generates neutral colors (grays and black) using only black toner. This guarantees neutrals colors without a color cast.
• 4-Color generates neutral colors (grays and black) by combining all four toner colors. This method produces smoother gradients and transitions to non-neutral colors, and it produces the darkest black.

Edge Control. The Edge Control setting determines how edges are rendered. Edge control has three components: adaptive halftoning REt, and trapping. Adaptive halftoning increases edge sharpness. Trapping reduces the effect of color plane misregistration by overlapping the edges of adjacent objects slightly. The color REt option increases the apparent resolution by placing each dot for the smoothest edges.

Four levels of edge control are available:

• Maximum is the most aggressive trapping setting. Adaptive halftoning is on for this setting.
- Normal is the default trapping setting. Trapping is at a medium level and adaptive halftoning and color REt is on.
• Light sets trapping at a minimal level, and adaptive halftoning and color REt is on.
- Off turns off trapping, adaptive halftoning, and color REt.

RGB Color. Two values are available for the RGB Color setting:

• Default instructs the printer to interpret RGB color as sRGB. sRGB is the accepted standard of Microsoft and the World Wide Web Organization (www).
• Vivid instructs the printer to increase the color saturation in the midtones so that colored objects appear more colorful. Printed blues and greens will likely appear darker than on your monitor. This option is good for business graphics or for producing colors similar to the HP Color LaserJet 4550.
• Device instructs the printer to print RGB data in raw device mode. To render photographs properly with this selection, you must manage image color in the application or operating system.

Note

HP Color LaserJet 4550 series Color Emulation can be accessed though the Print Task Quick Sets in the printer driver.

Matching colors

The process of matching printer output color to your computer screen is quite complex because printers and computer monitors use different methods of producing color. Monitors display colors by light pixels using an RGB (red, green, blue) color process, but printers print colors using a CMYK (cyan, magenta, yellow, and black) process.

Several factors can influence your ability to match printed colors to those on your monitor. These factors include:

• print media
  • printer colorants (inks or toners for example)
• printing process (inkjet, press, or laser technology for example)
  • overhead lighting
  • personal differences in perception of color
• software applications
• printer drivers
  • computer operating system
  • monitors
  • video cards and drivers
  • operating environment (humidity for example)

Keep the above factors in mind when colors on your screen do not perfectly match your printed colors.

For most users, the best method for matching colors on your screen to your printer is to print sRGB colors.

PANTONE®\* color matching

PANTONE®* has multiple color matching systems. PANTONE®* Matching System is very popular and uses solid inks to generate a wide range of color hues and tints. See http://www.hp.com/support/clj5550_software for details on how to use PANTONE®* Matching System with this printer.

Sample book color matching

The process for matching printer output to preprinted sample books and standard color references is complex. In general, you can obtain a reasonably good match to a sample book if the inks used to create the sample book are cyan, magenta, yellow, and black. These are usually referred to as process color sample books.

Some sample books are created from spot colors. Spot colors are specially created colorants. Many of these spot colors are outside of the gamut of the printer. Most spot color sample books have companion process sample books that provide CMYK approximations to the spot color.

Most process sample books will have a note on what process standards were used to print the sample book. In most cases they will be SWOP, EURO, or DIC. To get optimal color matching to the process sample book, select the corresponding ink emulation from the printer menu. If you cannot identify the process standard, use SWOP ink emulation.

Printing color samples

To use the Color samples, select the Color sample that is the closest match to the desired color. Use the sample's color value in your application to describe the object you wish to match. Colors may vary depending on paper type and the software application used. For more details on how to use the Color Samples, go to http://www.hp.com/support/clj5550.

Use the following procedure to print color samples at the printer using the control panel:

1. Press M ENU to enter the MENUS.
2. Press ▼ to highlight INFORMATION.
3. Press √ to select INFORMATION.
4. Press ▼ to highlight PRINT CMYK SAMPLES or PRINT RGB SAMPLES.
5. Press √ to select PRINT CMYK SAMPLES or PRINT RGB SAMPLES.

These samples are only accurate if you have not changed the defaults.

Color emulation of the HP Color LaserJet 4550

The PCL, PS, and HP Color LaserJet 5550 series printer drivers include a Print Task Quick Set called "HP Color LaserJet 4550 Color Emulation." This Print Task Quick Set allows you to easily set the printer to emulate the colors of the HP Color LaserJet 4550 printer. In general, the emulation color rendering has more contrast and is darker in appearance. This emulation works well with documents that contain graphics.

Periodic cleaning

To ensure the printer continues to function properly throughout its life, periodic cleaning is necessary.

One area of the printer that must be cleaned periodically is the overhead transparency (OHT) and two-sided printing (duplex) sensor. The OHT sensor detects and ensures that the printer uses the correct print mode. The sensor also corrects for paper skew on the second side of the page during two-sided (duplex) printing.

The static discharge comb at the top of the printer also needs periodic cleaning. A brush to clean the static discharge comb is stored inside the front cover.

When to clean the OHT sensor

The printer control panel reports paper is being used instead of the desired transparency.
• The images on the front and back of the printed page do not align.

Basic troubleshooting checklist

If you are experiencing problems with the printer, this checklist may help identify the cause of the problem.

• Is the printer connected to power?
Is the printer on?
• Is the printer in the Ready state?
• Are all necessary cables connected?
- Are any messages displayed on the control panel?
• Was a genuine HP supply installed?

- Were recently replaced print cartridges installed correctly? Was the pull tab on the cartridge removed?

- Were recently installed supply items (image fuser kit, image transfer kit) installed correctly?

If you cannot find solutions to printer problems in this guide, see http://www.hp.com/support/clj5550.

For additional information on installation and setup of the printer, see the start guide for this printer.

Factors affecting printer performance

Several factors affect the time it takes to print a job. Among these is maximum printer speed, measured in pages per minute (ppm). Other factors that affect printing speed include the use of special paper (such as transparencies, heavy paper, and custom-size paper), printer processing time, and download time. Other factors include:

• the complexity and size of graphics
• the printer I/O configuration (network versus parallel)
• the speed of the computer you are using
• the amount of printer memory installed
• the network operating system and configuration (if applicable)
• printer personality (PCL or PostScript 3 emulation)

Note

Adding additional printer memory might resolve memory problems, improve how the printer handles complex graphics, and improve download times, but it will not increase maximum printer speed (ppm rating).

Troubleshooting information pages

From the printer control panel, you can print pages that can help diagnose printer problems. The procedures for printing the following information pages are described here:

• paper path test page
- registration page
• event log

Paper path test page

The paper path test page is useful for testing the paper handling features of the printer. You can define the paper path you want to test by selecting the source, destination, and other options available on the printer.

1. Press M ENU to enter the MENUS.
2. Press ▼ to highlight DIAGNOSTICS.
3. Press √ to select DIAGNOSTICS.
4. Press ▼ to highlight PAPER PATH TEST.
5. Press √ to select PAPER PATH TEST.

The message Performing... PAPER PATH TEST appears on the display until the printer finishes the paper path test. The printer returns to the Ready state after printing the paper path test page.

Registration page

The registration page prints a horizontal arrow and a vertical arrow that shows how far from center an image can be printed on the page. You can set registration values for a tray so that an image on the back and front of a page is centered. Setting the registration also allows the image to be centered on the page. Image placement varies slightly for each tray. Perform the registration procedure for each tray.

1. Press M ENU to enter the MENUS.
2. Press ▼ to highlight CONFIGURE DEVICE.
3. Press √ to select CONFIGURE DEVICE.
4. Press ▼ to highlight PRINT QUALITY.
5. Press √ to select PRINT QUALITY.
6. Press ▼ to highlight SET REGISTRATION.
7. Press √ to select SET REGISTRATION.

Note

You can select a tray by specifying a SOURCE. The default SOURCE is Tray 2. To set the registration for Tray 2, go to step 12. Otherwise, proceed to the next step.

1. Press ▼ to highlight SOURCE.
2. Press √ to select SOURCE.

3. Press ▼ or ▲ to highlight a tray.

4. Press to select the tray.
   After selecting the tray, the printer control panel returns to the SET REGISTRATION menu.

5. Press ▼ to highlight PRINT TEST PAGE.
6. Press √ to select PRINT TEST PAGE.
7. Follow the instructions on the printed page.

Event log

The event log lists the printer events, including printer jams, service errors, and other printer conditions.

1. Press M_ENU to enter the MENUS.
2. Press ▼ to highlight DIAGNOSTICS.
3. Press √ to select DIAGNOSTICS.
4. Press ▼ to highlight PRINT EVENT LOG.
5. Press √ to select PRINT EVENT LOG.

The message Printing... EVENT LOG appears on the display until the printer finishes printing the event log. The printer returns to the Ready state after printing the event log.

Control panel message types

Control panel messages are divided into three types, depending on their severity.

• Status messages
• Warning messages
• Error messages

Within the error message category, some messages are ranked as Critical error messages. This section explains the differences between the control panel message types.

Status messages

Status messages reflect the current state of the printer. They inform you of normal printer operation and require no interaction to clear them. They change as the state of the printer changes. Whenever the printer is ready, not busy, and has no pending warning messages, the status message Ready is displayed if the printer is online.

Warning messages

Warning messages inform you of data and print errors. These messages typically alternate with the Ready or Status messages and remain displayed until the √ button is pressed. If CLEARABLE WARNINGS is set to JOB in the printer's configuration menu, these messages are cleared by the next print job.

Error messages

Error messages communicate that some action must be performed, such as adding paper or clearing a paper jam.

Some error messages are auto-continuable. If AUTO CONTINUE=ON is displayed, the printer will continue normal operation after displaying an auto-continuable error message for 10 seconds.

Note

Any button pressed during the 10-second display of an auto-continuable error message will override the auto-continue feature and the function of the button pressed will take precedence. For example, pressing the MENU button will cancel the job.

Critical error messages

Critical error messages inform you of a device failure. Some of these messages can be cleared by turning the printer off and then on. These messages are not affected by the AUTO CONTINUE setting. If a critical error persists, service is required.

The following table lists and describes control panel messages, in numerical and alphabetical order.

Paper jam recovery

This printer automatically provides paper jam recovery, a feature that allows you to set whether the printer should attempt to automatically reprint jammed pages. The options are:

• AUTO Printer will attempt to reprint jammed pages.
• OFF Printer will not attempt to reprint jammed pages.

Note

During the recovery process, the printer may reprint several good pages that were printed before the paper jam occurred. Be sure to remove any duplicated pages.

To disable paper jam recovery

1. Press M ENU to enter the MENUS.

2. Press ▼ to highlight CONFIGURE DEVICE.

3. Press to select CONFIGURE DEVICE.

4. Press ▼ to highlight SYSTEM SETUP.
5. Press √ to select SYSTEM SETUP.
6. Press ▼ to highlight JAM RECOVERY.
7. Press √ to select JAM RECOVERY.
8. Press ▼ to highlight OFF.
9. Press √ to select OFF.
10. Press the MENU button to return to the Ready state.

To improve print speed and increase memory resources, you may want to disable paper jam recovery. If paper jam recovery is disabled, the pages involved in a jam will not be reprinted.

Common causes of paper jams

The following table lists common causes of paper jams and suggested solutions for resolving them.

Cause Solution
Print media does not meet HP-recommended media specifications.	Use only media that meets HP specifications. See Supported paper weights and sizes.
A supply item is installed incorrectly, causing repeated jams.	Verify that all print cartridges, the transfer unit, and the fuser are correctly installed.
You are reloading paper that has already passed through a printer or copier.	Do not use media that has been previously printed on or copied.
An input tray is loaded incorrectly. Remove any excess media from the input tray. Press media down in the input tray so it fits below the tabs, and within the media width guides. See Configuring input trays.
Print media is skewed. Input tray guides are not adjusted correctly. Adjust input tray guides so they hold media firmly in place without bending it. If media heavier than 120 g/m² (32 lb) is loaded into Tray 2, 3, 4, or 5, the media might skew.
Print media is binding or sticking together.	Remove media, flex it, rotate it 180 degrees, or flip it over. Reload media into the input tray. Do not fan media.
Print media is removed before it settles into the output bin.	Reset the printer. Wait until the page completely settles in the output bin before removing it.
When duplexing, the print media is removed before the second side of the document is printed.	Reset the printer and print the document again. Wait until the page completely settles in the output bin before removing it.
Print media is in poor condition. Replace the print media.
Print media is not picked up by the internal rollers from Tray 2, 3, 4, or 5.	Remove the top sheet of media. If the media is heavier than 120 g/m² (32 lb), it may not be picked from the tray.
Print media has rough or jagged edges. Replace the media.
Print media is perforated or embossed. This media does not separate easily. You might need to feed single sheets from Tray 1.
Printer supply items have reached the end of their useful life.	Check the printer control panel for messages prompting you to replace supplies, or print a supplies status page to verify the remaining life of the supplies. See Replacing supplies for more information.
Media was not stored correctly. Replace the print media. Media should be stored in the original packaging in a controlled environment.NoteIf the printer continues to jam, contact HP Customer Support or your authorized HP service provider. For more information, see http://www.hp.com/support/clj5550.

Clearing paper jams

Each section below corresponds with a jam message that might appear on the control panel. Use these procedures to clear the jam.

Print quality troubleshooting

If you are experiencing problems with print quality, the following lists may help identify the cause of the problem.

Print quality problems associated with paper

Some print quality problems arise from use of inappropriate paper.

• Use paper that meets HP paper specifications. See Supported paper weights and sizes.
• The surface of the paper is too smooth. Use paper that meets HP paper specifications. See Supported paper weights and sizes.
• The driver setting is incorrect. To change the paper type setting, see Type and Size.
• The paper you are using is too heavy for the paper type setting you selected, and the toner is not fusing to the paper.
• The moisture content of the paper is uneven, too high, or too low. Use paper from a different source or from an unopened ream of paper.
• Some areas of the paper reject toner. Use paper from a different source or from an unopened ream of paper.
• The letterhead you are using is printed on rough paper. Use a smoother, xerographic paper. If this solves your problem, consult with the printer of your letterhead to verify that the paper used meets the specifications for this printer. See Supported paper weights and sizes.
• The paper is excessively rough. Use a smoother, xerographic paper.
• The transparencies you are using are not designed for proper toner adhesion. Use only transparencies designed for HP Color LaserJet printers.

Overhead transparency defects

Overhead transparencies may display any of the image quality problems that any other type of paper will cause, as well as defects specific to printing on transparencies. In addition, because transparencies are pliable while in the print path, they are subject to being marked by the paper-handling components.

Note

Allow transparencies to cool for at least 30 seconds before handling them.

• In the printer driver Paper tab, select Transparency as the paper type. Also, make sure that the tray is correctly configured for transparencies.
• Check that the transparencies meet the specifications for this printer. See Supported paper weights and sizes. For more information, consult the HP LaserJet Printer Family Print Media Guide. See http://www.hp.com/support/clj5550 for HP LaserJet Printer Family Print Media Guide ordering information. For downloadable manuals, go to http://www.hp.com/support/clj5550. When you connect, select Manuals.
• The transparencies you are using are not designed for proper toner adhesion. Use only transparencies designed for HP Color LaserJet printers.

• If the color is off and the printer control panel displays the 41.5 UNEXPECTED TYPE IN TRAY X LOAD TRAY X error, the OHT sensor might be dirty. See Periodic cleaning for OHT cleaning instructions.

• Handle transparencies by the edges. Skin oil on the surface of transparencies can cause spots and smudges.

• Small, random dark areas on the trailing edge of solid fill pages may be caused by transparencies sticking together in the output bin. Try printing the job in smaller batches.
• The selected colors are undesirable when printed. Select different colors in the software application or printer driver.
• If you are using a reflective overhead projector, use a standard overhead projector instead.

Print quality problems associated with the environment

Print quality problems can occur if the printer is operating in an environment outside of the printer specifications (see Printer specifications).

Print quality problems associated with jams

Make sure that all paper is cleared from the paper path. See Paper jam recovery.

• If the printer recently jammed, print two to three pages to clean the printer.
• If the paper does not pass through the fuser, which causes image defects to appear on subsequent documents, print two to three pages to clean the printer. However, if the problem persists see the next section.

Print quality problems associated with maintenance

Some print quality problems might occur when the printer needs cleaning. See Periodic cleaning for more information.

Print quality troubleshooting pages

The print quality troubleshooting pages provide information on aspects of the printer that affect print quality.

1. Press M ENU to enter the MENUS.
2. Press ▼ to highlight DIAGNOSTICS.
3. Press √ to select DIAGNOSTICS.
4. Press ▼ to highlight PQ TROUBLESHOOTING.
5. Press √ to select PQ TROUBLESHOOTING.

The message Printing... PQ troubleshooting appears on the display until the printer finishes printing the print quality troubleshooting information. The printer returns to the Ready state after printing the print quality troubleshooting information.

The print quality troubleshooting information includes one page for each color (cyan, magenta, yellow, and black), printer statistics related to print quality, instructions on interpreting the information, and procedures to solve print quality problems.

If following the procedures recommended by the print quality troubleshooting pages do not improve print quality, go to http://www.hp.com/support/clj5550.

Calibrating the printer

The HP Color LaserJet 5550 printer automatically calibrates and cleans at various times to maintain the highest level of print quality. The user may also request the printer to calibrate via the printer's control panel, using QUICK CALIBRATE NOW or FULL CALIBRATE NOW located in the CALIBRATION and PRINT QUALITY menu. QUICK CALIBRATE NOW is used for color tone calibration and takes about 90 seconds. If color density or tone seems wrong, Quick Calibration can be run. Full Calibration includes the Quick Calibrate routines and adds Drum Phase Calibration and Color Plane Registration (CPR). This takes about 3 minutes and 30 seconds. If color layers (cyan, magenta, yellow, black) on the printed page seem to be shifted from one another, Full Calibration should be run.

The HP Color LaserJet 5550 printer incorporates a new feature to skip calibration when appropriate, making the printer available more quickly. For example, when the power switch is turned off, then on again quickly, calibration is not needed and will be skipped. This saves approximately one minute in time to be ready.

The printer may pause printing while it is calibrating or cleaning. When possible, the printer will wait for the job to complete before calibrating or cleaning.

1. Press MENU to enter the MENUS.
2. Press ▼ to highlight CONFIGURE DEVICE.
3. Press √ to select CONFIGURE DEVICE.
4. Press ▼ to highlight PRINT QUALITY.

Safety statements

Laser safety

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.
