USING PRINT MATERIALS

This chapter will help you understand types of paper you can use with your printer and how to properly load paper in the different paper trays for the best print quality.

This chapter includes:

• Choosing Paper and Other Materials
• Selecting the Output Location
• Loading Paper
• Printing on Envelopes
• Printing on Labels
• Printing on Transparencies
• Printing on Card Stock or Custom-sized Materials
• Printing on Preprinted Paper

Choosing Paper and Other Materials

You can print on a variety of print materials, such as plain paper, envelopes, labels, transparencies, and so on. See "Paper Specifications" on page E.3. To get the best possible print quality, use only high-quality copier-grade paper.

When you choose print materials, consider the following:

• Desired outcome: The paper you choose should be appropriate for the project.
• Size: You can use any size paper that fits easily within the paper adjusters of the paper tray.
• Weight : Your printer supports paper weight as follows:
  -16\~24 lbs (60\~90 g/m²) bond for the Tray1 or optional Tray2 -16\~43 lbs (60\~163 g/m²) bond for the Multi-Purpose Tray
• Brightness: Some papers are whiter than others and produce sharper, more vibrant images.
• Surface smoothness: The smoothness of the paper affects how crisp the printing looks on the paper.

CAUTION: Using a material that does not conform to the specifications listed in the paper specification can cause problems that may require service. This service is not covered by the warranty or service agreements.

^* a Depending on paper thickness, the maximum capacity may be reduced.

*b If you are experiencing excessive jamming, feed one sheet at a time through the Multi-Purpose Tray.

Guidelines for Paper and Special Materials

When selecting or loading paper, envelopes, or other special materials, keep these guidelines in mind:

• Attempting to print on damp, curled, wrinkled, or torn paper can cause paper jams and poor print quality.
• Use cut-sheet paper only. You cannot use multi-part paper.
• Use only high-quality, copier grade paper for the best print quality.
• Do not use paper that has already been printed on or that has been fed through a photocopier.

- Do not use paper with irregularities, such as tabs or staples.

- Do not attempt to load any tray during printing and never overfill the tray. This could cause a paper jam.

- Avoid paper with embossed lettering, perforations, or texture that is too smooth or too rough.

- Coloured paper should be of the same high quality as white photocopy paper. The pigments must withstand the printer's fusing temperature of 400^ (205°C) for 0.1 second without deterioration. Do not use paper with a coloured coating that was added after the paper was produced.

- Preprinted forms must be printed with nonflammable, heat-resistant inks that do not melt, vaporize, or release hazardous emissions when subject to the printer's approximately 400°F (205°C) fusing temperature for 0.1 second.

- Store paper in its ream wrapper until ready to use. Place cartons on pallets or shelves, not on the floor.

- Do not place heavy objects on top of the paper, whether it is packaged or unpackaged.

- Keep paper away from moisture, direct sunlight, or other conditions that can cause it to wrinkle or curl.

NOTE: Do not use carbonless paper or tracing paper. They are unstable at the fusing temperature and can give off fumes, or cause damage to the paper.

Selecting the Output Location

The printer has two output locations; the rear output tray and the top output tray.

Top output tray Rear output tray

To use the top output tray, be sure that the rear output tray is closed. To use the rear output tray, open it.

NOTES:

• If paper coming out of the top output tray has problems, such as excessive curl, try printing to the rear output tray.
• To avoid paper jams, do not open or close the rear output tray while the printer is printing.

Printing to the Top Output Tray (Face down)

The top output tray collects paper face-down, in the order in which it was printed. The top output tray should be used for most print jobs.

Illustration of a printer with a blue cover and paper filter (no text or symbols)

NOTE: If you continuously print many pages, the surface of the output tray may become hot. Be careful not to touch the surface, and especially keep children away from the surface.

Printing to the Rear Output Tray (Face up)

The printer always prints to the rear output tray if it is open. Paper comes out of the printer face-up, and each time a sheet of paper comes out, it falls down from the printer.

Illustration of a printer with paper being inserted, showing internal structure and a blue arrow indicating print direction (no text or symbols present)

Printing from the Multi-Purpose Tray to the rear output tray provides a straight paper path. Opening the rear output tray might improve the output quality with the following:

• envelopes
• labels
• transparencies

To open the rear output tray:

1 Open the rear door by pulling it down. The cover functions as the output tray.

Illustration of a hand opening a computer tower with a blue arrow indicating the process (no text or symbols present)

CAUTION: The fusing area at the rear portion of the inside of your printer is hot when powered. Be careful not to be burned when accessing this area.

2 If you do not want to use the rear output tray, close the tray. The pages will stack on the top output tray.

Loading Paper

Proper paper loading helps prevent paper jams and ensure trouble-free printing. Do not remove the paper tray while a job is printing. Doing so may cause a paper jam. See "Sizes and Capacities" on page 3.3 for acceptable paper size and capacities for each tray.

The paper level bar on the front of the paper tray(s) shows the amount of paper currently left in the tray. When the tray is empty, the indicator drops to the bottom.

▲ Paper emptyPaper full

Using Tray1 or the Optional Tray2

Tray1 and the optional Tray2 can hold up to 250 sheets of paper. See "Sizes and Capacities" on page 3.3 for acceptable paper size and capacities of each tray.

Tray1 Optional Tray2

Load a stack of paper into the tray and print. For details about loading paper in Tray1 or the optional Tray2, see "Loading Paper" on page 2.7.

Using the Multi-Purpose Tray

The multi-Purpose Tray is located in the front of your printer. It can be closed when you are not using it, making the printer more compact.

Multi-Purpose Tray

The Multi-Purpose Tray can hold several sizes and types of paper, such as transparencies, cards, and envelopes. You may also want to use the Multi-Purpose Tray for single page print jobs on letterhead, coloured paper for use as separator sheets, or other special materials that you do not normally keep in the paper tray. You can load approximately 50 sheets of plain paper, 5 envelopes, 5 transparencies, 5 sheets of card stock or 5 labels at a time.

• Load only one size of print material at a time in the Multi-Purpose Tray.
• To prevent paper jams, do not add paper when there is still paper in the Multi-Purpose Tray. This also applies to other types of print materials.
• Print materials should be loaded face up with the top edge going into the Multi-Purpose Tray first and be placed on the centre of the tray.
• Do not place objects on the Multi-Purpose Tray. Also avoid pressing down or applying excessive force on it. The tray may fall from the printer.

To load paper in the Multi-Purpose Tray:

1 Pull the Multi-Purpose Tray down towards you.

3 Prepare a stack of paper for loading by flexing or fanning the paper back and forth. Straighten the edges on a level surface.

Illustration of two hands holding a curved object on a base, with directional arrows indicating movement (no text or symbols)

4 Place paper on the centre of the tray with the print side face up. Pay attention to the paper limit mark on the left inside wall of the tray. Paper overloading may cause paper jams.

Illustration of a printer with an arrow indicating paper movement, showing internal structure and a magnified inset of the printer handle (no text or symbols present)

If you want to print on previously printed paper from the Multi-Purpose Tray, the printed side should be facing down with an uncurled edge to the printer. If you experience problems with paper feed, turn the paper around.

Illustration of a printer emitting a paper with an arrow indicating the paper's direction (no text or symbols present)

NOTE: Make sure that you have not loaded too much print material. The print material buckles if you load a stack that is too deep or push it in too far.

5 Slide the paper width guide and adjust it against the stack of print material without bending.

Illustration of a printer with paper feed and a magnified inset showing the printer's internal structure (no text or symbols)

NOTE: Your printer cannot automatically detect the size of paper loaded in the Multi-Purpose Tray. Loading the Multi-Purpose Tray with the correct paper size allows you to select paper by size rather than paper source when you print from your software application. You do not have to check which paper is loaded in the Multi-purpose Tray before printing.

Using the Manual Feed Mode

If you select Manual Feed in the Source option when changing print settings, you can manually load a sheet of print material in the Multi-Purpose Tray. Manually loading paper can be helpful when you want to check the print quality after each page is printed.

This loading procedure is almost the same as the procedure for loading in the Multi-Purpose Tray, except you load paper sheet-by-sheet in the Tray, send print data to print the first page, and press the Cancel button on the control panel to print each following page.

1 Load a sheet of print material on the centre of the Multi-Purpose Tray with the print side up.

Repeat this step for every page to be printed.

Printing on Envelopes

Guidelines

- Only use envelopes recommended for laser printers. Before loading envelopes into the Multi-Purpose Tray, make sure that they are undamaged and are not stuck together.

- Do not feed stamped envelopes.

- Never use envelopes with clasps, snaps, windows, coated lining, or self-stick adhesives. These envelopes may severely damage the printer.

Printing on Labels

Guidelines

• Only use labels recommended for laser printers.
• Verify that the labels' adhesive material can tolerate fusing temperature of 205^ (400°F) for 0.1 second.
• Make sure that there is no exposed adhesive material between the labels. Exposed areas can cause labels to peel off during printing, which can cause paper jams. Exposed adhesive can also cause damage to printer components.
• Do not feed a sheet of labels through the printer more than once. The adhesive backing is designed for one pass through the printer.
• Do not use labels that are separating from the backing sheet or are wrinkled, bubbled, or otherwise damaged.

1 Open the Multi-Purpose Tray and the rear output tray.

5 After printing, close the Multi-Purpose Tray and the rear output tray.

NOTE: To prevent labels from sticking, do not let the printed label sheets stack up as they are printed out.

Printing on Transparencies

Guidelines

• Only use transparencies recommended for use in laser printers.
• Ensure that transparencies are not wrinkled, curled, or have any torn edges.
• Hold the transparencies by the edges and avoid touching the print side. Oils deposited on the transparency can cause print quality problems.
• Be careful not to scratch or leave fingerprints on the print side.

1 Open the Multi-Purpose Tray and the rear output tray.

5 After printing, close the Multi-Purpose Tray and the rear output tray.

NOTES:

- If you print on thin transparencies to the rear output tray, they can curl. In this case, use the top output tray. If the problem persists, check if your transparencies meet the printer's specifications.

- To prevent transparencies from sticking, do not let the printed sheets stack up as they are printed out.

- Place transparencies on a flat surface after removing them from the printer.

Printing on Card Stock or Custom-sized Materials

Postcards, 3.5 by 5.83 in. (index) cards and other custom-sized materials can be printed with your printer. The minimum size is 76 by 127 mm (3 by 5 in.) and the maximum size is 216 by 356 mm (8.5 by 14 in.).

Guidelines

- Always insert the short-edge into the Multi-Purpose Tray first. If you want to print in landscape mode, make this selection through your software. Inserting paper long-edge first may cause a paper jam.

- Do not load more than 5 cards into the Multi-Purpose Tray at a time.

- Do not print on media smaller than 76 mm (3 in.) wide or 127 mm(5 in.) long.

- Set margins at least 6.4 mm (0.25 in.) away from the edges of the material in the software application

1 Open the Multi-Purpose Tray and the rear output tray.
2 Load print material with print side up and short edge first.

NOTE: If the size of your print material is not listed in the Size box in the Paper tab of the printer driver properties, click the Custom button and set the size manually. See page 4.7.

CAUTION: When you use 76 by 127 mm (3 by 5 in.) paper and it is too thin, a paper jam may occur. Use card stock heavier than 105g/m^2

5 After printing, close the Multi-Purpose Tray and the rear output tray.

Printing on Preprinted Paper

Preprinted paper is paper that has some type of printing placed on it before it is sent through the printer (paper that has a preprinted logo at the top of the page, for example).

Guidelines

• Letterheads must be printed with heat-resistant ink that will not melt, vaporize, or release hazardous emissions when subjected to the printer's fusing temperature of 400 °F (205 °C) for 0.1 second.
• Ink on letterheads 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 you load preprinted paper as forms and letterhead, verify that the ink on the paper is dry. During the fusing process, wet ink can come off preprinted paper.

1 Load letterhead into the tray you want to use, as shown in the figures below. Adjust the guides to fit the width of the paper stack.

Load with the design face down, bottom edge towards the printer.

Using Overlays

What is an Overlay?

Dear ABC Rogars WORLD BEST

An overlay is text and/or images stored in the computer hard disk drive (HDD) as a special file format that can be printed on any document. Overlays are often used to take the place of preprinted forms and letterhead paper. Rather than using preprinted letterhead, you can create an overlay containing the exact same information that is currently on your letterhead. To print a letter with your company's letterhead, you do not need to load preprinted letterhead paper in the printer. You need only tell the printer to print the letterhead overlay on your document.

Creating a New Page Overlay

WORLD BEST

To use a page overlay, you must create a new page overlay containing your logo or image.

1 Create or open a document containing text or an image for use in a new page overlay. Position the items exactly as you wish them to appear when printed as an overlay. If needed, save the file for later use.
2 To change the print settings from your software application, access the printer properties. See page 4.2.

MAINTAINING YOUR PRINTER

This chapter provides suggestions for high-quality and economical printing and information for maintaining the toner cartridge and the printer.

This chapter includes:

• Maintaining the Toner Cartridge
• Cleaning the Printer
• Printing Configuration Pages
• Consumables and Replacement Parts

Maintaining the Toner Cartridge

Toner cartridge storage

To get the maximum results from the toner cartridge, keep the following guidelines in mind.

• Do not remove the toner cartridge from its package until ready for use.
• Do not refill the toner cartridge. The printer warranty does not cover damage caused by using a refilled cartridge.
• Store toner cartridges in the same environment as the printer.
• To prevent damage to the toner cartridge, do not expose it to light for more than a few minutes.

Toner cartridge life expectancy

The life of the toner cartridge depends on the amount of toner that print jobs require. When printing text at 5% coverage, a new toner cartridge lasts an average of 5,000 pages.

Saving toner

To save toner, press the Cancel button on the printer control panel for 0.5 second. The button will be lit. You can also enable the Toner Save in the printer properties. Refer to "Using the Toner Save Mode" on page 4.9. Selecting this option will extend the life of the toner cartridge and reduce your cost per page, but will reduce the print quality.

Redistributing Toner

When toner is low, faded or light areas may appear on a printed page. You may be able to temporarily improve the print quality by redistributing the toner. The following procedures may allow you to finish the current print job before replacing the toner cartridge.

1 Grasp the front cover and pull it toward you to open.

2 Pull the toner cartridge and remove it from the printer.

Illustration of a printer being inserted into a plastic case, showing the paper inside (no text or symbols)

CAUTIONS:

- Avoid reaching too far into the printer. The fusing area may be hot.

- To prevent damage to the toner cartridge, do not expose it to light for more than a few minutes. Cover it with a piece of paper, if left exposed for more than a few minutes and keep it in a flat and clean place.

3 Gently shake the toner cartridge from side to side five or six times to redistribute the toner.

Illustration of hands holding a mechanical component with blue curved arrows indicating rotation (no text or symbols)

NOTE: If toner gets on your clothing, wipe it off with a dry cloth and wash clothing in cold water. Hot water sets toner into fabric.

4 Reinsert the toner cartridge into the printer. Ensure that the toner cartridge snaps into place.

5 Close the front cover. Make sure that the cover is securely closed. If it is not firmly closed, printing errors may occur when you print.

Illustration of a printer with a blue arrow indicating the process, showing internal components and a clear cover (no text or symbols present)

Replacing the Toner Cartridge

If the print remains light after redistributing the toner (see page 5.3), replace the toner cartridge.

Remove the old cartridge and install a new toner cartridge. See "Installing the Toner Cartridge" on page 2.4.

Cleaning the Printer

To maintain print quality, follow the cleaning procedures below each time the toner cartridge is replaced or if print quality problems occur.

NOTE: While cleaning the inside of the printer, be careful not to touch the transfer roller (located underneath the toner cartridge). Oil from your fingers can cause print quality problems.

CAUTION: Cleaning the cabinet of the printer with surfactants containing large amounts of alcohol, solvent, or other strong substances can discolor or crack the cabinet.

Cleaning the Outside

Clean the cabinet of the printer with a soft, lint-free cloth. You can dampen the cloth slightly with water, but be careful not to let any water drip onto the printer or inside of it.

Cleaning the Inside

During the printing process, paper, toner, and dust particles can accumulate inside the printer. This buildup can cause print quality problems, such as toner specks or smearing. Cleaning the inside of the printer will eliminate or reduce these problems.

Cleaning inside the printer

1 Turn the printer off and unplug the power cord, then wait for the printer to cool.

2 Open the front cover. Pull the toner cartridge and remove it from the printer.

6 Plug in the power cord, and turn the printer on.

Printing a cleaning sheet

Your printer can be set to print out a cleaning sheet automatically every 500 print pages. you should use this feature if you use inferior quality paper, because such paper may lower print quality. See page C.6. This feature activates as a default depending on the country.

If you are experiencing blurred, faded, or smeared printouts, printing a cleaning sheet will clean the drum inside the toner cartridge. This process will produce a page with toner debris, which should be discarded.

1 Ensure that the printer is turned on and in the Ready mode with paper loaded in the tray.

2 Press and hold down the Cancel button on the control panel for about 10 seconds.

On Line/Error Toner Save Canc

3 Your printer automatically picks up a sheet of paper from the tray and prints out a cleaning sheet with dust or toner particles on it.

NOTE: The cartridge cleaning process takes some time. To stop the process, turn the power off.

Printing Configuration Pages

From the printer's control panel, you can print a Configuration page. Use the configuration page to view current printer settings, to help troubleshoot printer problems, or to verify installation of optional accessories, such as memory, optional tray, and printer languages.

If your printer has a network card, the network configuration sheet prints out with a printer configuration sheet.

To print configuration pages:

1 Ensure that the printer is turned on and in the Ready mode with paper loaded in the tray.

2 Press and hold down the Cancel button on the control panel for about 6 seconds.

Configuration pages print out.

See "Paper Specifications" on page E.3.Check the printer's environment; very dry (low humidity) or high humidity (higher than 80% RH) conditions can increase the amount of background shading.Remove the old toner cartridge and install a new one. See "Installing the Toner Cartridge" on page 2.4.
Toner smear	Clean the inside of the printer. See "Cleaning the Inside" on page 5.5.Check the paper type and quality. See "Paper Specifications" on page E.3.Remove the toner cartridge and install a new one. See "Installing the Toner Cartridge" on page 2.4.
Vertical repetitive defects	If marks repeatedly appear on the printed side of the page at even intervals:The toner cartridge may be damaged. If a repetitive mark occurs on the page, print a cleaning sheet several times to clean the cartridge; see page 5.7. After the printout, if you still have the same problems, install a new toner cartridge. See "Installing the Toner Cartridge" on page 2.4.Parts of the printer may have toner on them. If the defects occur on the back of the page, the problem will likely correct itself after a few more pages.The fusing assembly may be damaged. Contact a service representative.
Problem Solution
Background scatter	Background scatter results from bits of toner distributed on the printed page.The paper may be too damp. Try printing with a different batch of paper. Do not open packages of paper until necessary so that the paper does not absorb too much moisture.If background scatter occurs on an envelope, change the printing layout to avoid printing over areas that have overlapping seams on the reverse side. Printing on seams can cause problems.If background scatter covers the entire surface area of a printed page, adjust the print resolution through your software application or the printer properties.
Misformed characters	If characters are improperly formed and producing hollow images, the paper stock may be too slick. Try a different paper. See "Paper Specifications" on page E.3.If characters are improperly formed and producing a wavy effect, the scanner unit may need service. Verify that it also occurs on a demo page (see page 2.16). For service, contact a service representative.
Page skew	Check the paper type and quality. See "Paper Specifications" on page E.3.Ensure that the paper or other material is loaded correctly and the guides are not too tight or too loose against the paper stack.
Curl or wave	Check the paper type and quality. Both high temperature and humidity can cause paper curl. See "Paper Specifications" on page E.3.Turn over the stack of paper in the tray. Also try rotating the paper 180^ in the tray.Try printing to the face up output slot.
Wrinkles or creases	Ensure that the paper is loaded properly.Check the paper type and quality. See "Paper Specifications" on page E.3.Open the rear cover and try printing to the rear output tray (face-up).Turn over the stack of paper in the paper tray. Also try rotating the paper 180° in the tray.
Back of printouts are dirty	The transfer roller may be dirty. "Cleaning the Inside" on page 5.5.Check for leaking toner. Clean the inside of the printer.
Black pages	The toner cartridge may not be installed properly. Remove the cartridge and reinsert.The toner cartridge may be defective and need replacing.Install a new toner cartridge.The printer may require repair. Contact a service representative.
Loose toner	Clean the inside of the printer.Check the paper type and quality. See "Paper Specifications" on page E.3.Install a new toner cartridge. See "Installing the Toner Cartridge" on page 2.4.If the problem persists, the printer may require repair. Contact a service representative.
Character Voids	Character voids are white areas within the parts of characters that should be solid black:If you are using transparencies, try another type of transparency. Because of the composition of the transparency, some character voids are normal.You may be printing on the wrong side of the paper. Remove the paper and turn it around.The paper may not meet paper specifications. See "Paper Specifications" on page E.3.
Horizontal stripes	If horizontally aligned black streaks or smears appear:The toner cartridge may be installed improperly. Remove the cartridge and reinsert.The toner cartridge may be defective. Install a new toner cartridge. See "Installing the Toner Cartridge" on page 2.4.If the problem persists, the printer may require repair. Contact a service representative.
Curl	If the printed paper is curl or paper does not feed into the printer:Turn over the stack of paper in the input tray. Also try rotating the paper 180^ in the input tray.

Common Windows Problems

Problem Possible	Cause and Solution
"File in Use" message appears during installation.	Exit all software applications. Remove all software from the StartUp Group, then restart Windows. Reinstall the printer driver.
"Error Writing to LPTx" message appears.	· Ensure that the cables are connected correctly, and the printer is on.· If bi-directional communication is not turned on in the driver, it will also cause this message.
"General Protection Fault", "Exception OE", "Spool32", or "Illegal Operation" messages appear.	Close all other applications, reboot Windows, and try printing again.

NOTE: Refer to the Microsoft Windows 9x/Me/NT 4.0/2000/XP User's Guide that came with your PC for further information on Windows error messages.

Troubleshooting PS Errors

The following situations are PS language specific and may occur when several printer languages are being used.

NOTE: To receive a printed or screen displayed message when PS errors occur, open the Print Options window and click the desired selection next to the PostScript errors section.

Problem Possible Cause Solution
PostScript file can not be printed.	The PostScript option may not be installed.	· Print a configuration page and verify that the PS version is available for printing.· If PostScript is not available, install the PostScript option. See "Installing Memory and PostScript DIMMs" on page D.3.
"This job contains binary data..." message appears.	The pure binary data option is not supported by the PostScript driver.	Open the Properties of the PostScript driver, click onPostScript, and click onAdvanced. The pure binary data option is not supported. Choose another.
The optional Tray2 is not selected in the driver.	The printer driver has not been configured to recognise the optional Tray2.	Open the PostScript driver properties and set theTray2item of theDeviceoptiontoInstalled.

Common Linux Problems

Problem Possible Cause and Solution
I can't change settings in the configuration tool.	You need to have administrator privileges to be able to affect global settings.
I am using the KDE desktop but the configuration tool and LLPR won't start.	Maybe you do not have the GTK libraries installed. These usually come with most Linux distributions, but you may have to install them manually. Refer to your distribution's installation manual for more details about installing additional packages.
I just installed this package but can't find entries in the KDE/Gnome menus.	Some versions of the KDE or GNOME desktop environments may require that you restart your session for the changes to take effect.
I get a "Some options are not selected" error message while editing the printer settings.	Some printers have conflicting settings, meaning that some settings for two options can't be selected at the same time. When you change a setting and the Printer Package detects such a conflict, the conflicting option is changed to a "No Choice" value, and you have to choose an option that does not conflict before being able to submit the changes.
I can't make a printer the system default.	In some conditions, it may not be possible to change the default queue. This happens with some variants of LPRng, especially on recent RedHat systems that use the "printconf" database of queues.When using printconf, the /etc/printcap file is automatically refreshed from the database of printers managed by the system (usually through the "printtool" command), and the queues in /etc/printcap.local are appended to the resulting file. Since the default queue in LPRng is defined as the first queue in /etc/printcap, it is not possible for the Linux Printer Package to change the default when some queues have otherwise been defined using printtool.LPD systems identify the default queue as the one named "lp". Thus, if there is already a queue by this name, and if it doesn't have any alias, you won't be able to change the default. To work around this, you can either delete the queue or rename it by manually editing the /etc/printcap file.
The N-up setting does not work correctly for some of my documents.	The N-up feature is achieved through post-processing of the PostScript data that is being sent to the printing system. However, such post-processing can only be adequately achieved if the PostScript data conforms to the Adobe Document Structuring Conventions. Problems may arise when using N-up and other features relying on post-processing if the document being printed isn't compliant.
I am using BSD lpr (Slackware, Debian, older distributions) and some options chosen in LLPR don't seem to take effect.	Legacy BSD lpr systems have a hard limitation on the length of the option string that can be passed to the printing system. As such, if you selected a number of different options, the limitation length of the options may be exceeded and some of your choices won't be passed to the programmes responsible for implementing them. Try to select less options that deviate from the defaults, to save on memory usage.
I am trying to print a document in Landscape mode, but it prints rotated and cropped.	Most Unix applications that offer a Landscape orientation option in their printing options will generate correct PostScript code that should be printed as is. In that case, you need to make sure that you leave the LLPR option to its default Portrait setting, to avoid unwanted rotations of the page that would result in a cropped output.
Some pages come out all white (nothing is printed), and I am using CUPS.	If the data being sent is in Encapsulated PostScript (EPS) format, some earlier versions of CUPS (1.1.10 and before) have a bug preventing them from being processed correctly. When going through LLPR to print, the Printer Package will work around this issue by converting the data to regular PostScript. However, if your application bypasses LLPR and feeds EPS data to CUPS, the document may not print correctly.
I can't print to a SMB (Windows) printer.	To be able to configure and use SMB-shared printers (such as printers shared on a Windows machine), you need to have a correct installation of the SAMBA package that enables that feature. The "smbclient" command should be available and usable on your system.
My application seems to be frozen while LLPR is running.	Most Unix applications will expect a command like the regular "lpr" command to be non-interactive and thus return immediately. Since LLPR is waiting for user input before passing the job on to the print spooler, very often the application will wait for the process to return, and thus will appear to be frozen (its windows won't refresh). This is normal and the application should resume functioning correctly after the user exits LLPR.
How do I specify the IP address of my SMB server?	It can be specified in the "Add Printer" dialogue of the configuration tool, if you don't use the CUPS printing system. Unfortunately, CUPS currently doesn't allow one to specify the IP address of SMB printers, so you will have to be able to browse the resource with Samba in order to be able to print.
Some documents come out as white pages when printing.	Some versions of CUPS, especially those shipped with Mandrake Linux before the 8.1 release, have some known bugs when processing the PostScript output from some applications. Try upgrading to the latest version of CUPS (at least 1.1.14). Some RPM packages for most popular distributions are provided as a convenience with this Linux Printing Package.
I have CUPS and some options (such as N-up) seem to be always enabled even though I don’t pick them in LLPR.	There may be some local options defined in your ~/.Ipoptions file, which is manipulated by the Ipoptions command. These options will always be used if not overridden by LLPR settings. To get rid of all options for a printer, run the following command, replacing “printer” with the name of the queue: Ipoptions -x printer
I configured a printer to print to a file, but I get “Permission denied” errors.	Most printing systems will not run as the super-user but as a special user (usually “lp”). Therefore, make sure that the file you have chosen to print to is accessible to the user owning the spooler daemon.
On my SPL (or PCL) printer, I sometimes get error messages printing instead of my document.	Unfortunately, some Unix applications may generate non-compliant PostScript output that may not be supported by Ghostscript, or even the printer itself in PostScript mode. You can try to capture the output to a file and view the results with Ghostscript (gv or ghostview will allow you to do so interactively) and see if you get error messages. However, since the application is probably at fault, contact your software vendor to inform them of the issue.

PRINTING FROM DOS APPLICATIONS

While your printer is primarily a Windows printer, you can also print from a DOS software Programme using the Remote Control Panel utility provided in the supplied software CD-ROM.

This chapter includes:

• About the Remote Control Panel
  • Installing the Remote Control Panel
• Selecting Print Settings

About the Remote Control Panel

DOS users have access to many printer features through specific DOS printer drivers; however, many software manufactures do not develop printer drivers for their software programmes. Your printer provides the software control panel for improved printer control when DOS printer drivers are not available or when certain print settings are not available through DOS software programmes.

NOTE: The printer's Remote Control Panel is not a printer driver. It should be used to set print settings that are not available through DOS software programmes. Printer drivers are supplied by the manufacturers of your DOS software programmes. If your DOS software Programme does not include a printer driver for your printer, contact the manufacturer of the software or use one of the alternate printer drivers.

Installing the Remote Control Panel

1 Insert the supplied CD-ROM into your CD-ROM drive.

The CD-ROM should automatically run and an maintenance window appears.

1 If the maintenance window does not appear, click Start and then Run. Type X:\Setup.exe, replacing "X" with the letter of your drive and click OK.

- Emulation selects the emulation for printing a document. The factory default is Auto.

- Power Save determines the length of time the printer waits after a job is printed before it goes to a reduced power state. If the printer is used frequently, select OFF which keeps the printer ready to print with the minimum warm-up time. This uses more power to keep the printer warm and ready to print.

- Auto Continue determines what action the printer should take if the Multi-Purpose Tray is empty when a manual feed print job is sent to the printer. If it is checked, the printer will pick up the paper from the tray 1 after fifteen seconds. Otherwise, the printer will wait for you to load paper in the Multi-Purpose Tray.

- Jam Recovery determines what action the printer should take when a paper jam occurs. If it is unchecked, the printer does not reprint a page that has jammed. If it is checked, the printer keeps the image in memory for a printed page until the printer signals that the page has successfully printed. The printer reprints all jammed pages.

- Toner save determines the toner quantity the printer should use when printing. If it is checked, the printer conserves toner when printing. The default value is unchecked, which provides 100% usage.

- Auto Clean Drum makes the printer print out a cleaning sheet which clean the drum inside the toner cartridge automatically every 500 print pages. This feature activates as a default depending on the country.

INSTALLING PRINTER OPTIONS

Your printer is a full-featured laser printer that has been optimised to meet most of your printing needs. Recognizing that each user may have different requirements, however, Samsung makes several options available to enhance the printer's capabilities.

This chapter includes:

• Precautions When Installing Printer Options
  • Installing Memory and PostScript DIMMs
  • Installing a Network Card
  • Installing an Optional Paper Tray

Precautions When Installing Printer Options

Never remove the printer control board while the printer is plugged in.

To avoid the possibility of an electrical shock, always disconnect the power cord when installing or removing ANY internal or external printer option.

DISCHARGE STATIC ELECTRICITY:

The control board and internal printer options (Memory and PS DIMMs, Network cards) are sensitive to static electricity. Before installing or removing an internal option, discharge static electricity from your body by touching something metal, such as the metal back plate on any device plugged into a grounded power source. If you walk round before finishing installation, discharge any static electricity once again.

Paper Specifications

Overview

Your printer accepts a variety of print materials, such as cut-sheet paper (including up to 100% recycled fiber content paper), envelopes, labels, transparencies, and custom-size paper. Properties, such as weight, composition, grain, and moisture content, are important factors affecting the printer's performance and the output quality. Paper that does not meet the guidelines outlined in this User's Guide can cause the following problems:

• Poor print quality
• Increased paper jams
  • Premature wear on the printer.

NOTES:

- Some paper may meet all of the guidelines in this guide and still not produce satisfactory results. This may be the result of improper handling, unacceptable temperature and humidity levels, or other variables over which Samsung has no control.

- Before purchasing large quantities of paper, ensure that the paper meets the requirements specified in this User's Guide.

CAUTION: Using paper that does not meet these specifications may cause problems, requiring repairs. These repairs are not covered by the Samsung warranty or service agreements.

c Smoothness: 100 to 250 (Sheffield)

NOTE: You may experience jams when using print materials with a length of less than 127 mm (5.0 in.). For optimum performance, ensure that you are storing and handling the paper correctly. Please refer to "Printer and Paper Storage Environment" on page E.7.

Guidelines for Using Paper

For the best result, use conventional 75 g/m ^2 (20 lb) paper. Ensure that 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 of what type of paper you are loading, such as bond or recycled paper, check the label on the package.

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

Symptom	Problem with Paper	Solution
Poor print quality or toner adhesion, problems with feeding	Too moist, too rough, too smooth, or embossed; faulty paper lot	Try another kind of paper, between 100 ~ 250 Sheffield, 4 ~ 5 % moisture content.
Dropout, jamming, curl	Stored improperly	Store paper flat in its moisture-proof wrapping.
Increased gray background shading/printer wear	Too heavy	Use lighter paper, open the rear output tray.
Excessive curl problems with feeding	Too moist, wrong grain direction, or short-grain construction	Open the rear output tray.Use long-grain paper.
Jamming, damage to printer	Cutouts or perforations	Do not use paper with cutouts or perforations.
Problems with feeding	Ragged edges Use good quality paper.

NOTES:

• Do not use letterhead paper 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. Insure that any coloured paper or preprinted forms use inks that are compatible with this fusing temperature (205 °C or 400 °F for 0.1 second).

Printer and Paper Storage Environment

Paper storage environment conditions directly affect the feed operation.

Ideally, the printer and paper storage environment should be at or near room temperature, and not too dry or humid. Remember that 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 become distorted. This can cause paper jams.

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

Unopened paper in sealed reams can remain stable for several months before use. Opened packages of paper have more potential for environment 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 optimum condition is 20° to 24°C (68° to 75°F), with a relative humidity of 45% to 55%. The following guidelines should be considered 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.
• 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 90 ~g / m^2 (24 lb) or jamming may occur.
• Construction: Prior to printing, envelopes should lie flat with less than 6 mm (0.25 in.) 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 only use envelopes within the following size ranges.

	Minimum Maximum
Multi-Purpose Tray	76 X 127 mm(3 X 5 in.)	216 X 356 mm(8.5 X 14 in.)

NOTES:

• Use only the Multi-Purpose Tray to print envelopes.
• You may experience some paper jams when using any media with a length less than 127 mm (5.0 in.). This may be caused by paper that has been affected by environmental conditions. For optimum performance, make sure you are storing and handling the paper correctly. Please refer to "Printer and Paper Storage Environment" on page E.7.

Envelopes with Double Side Seams

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

Correct Incorrect

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 may even damage the fuser.

Envelope Margins

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

Type of Address	Minimum Maximum
Return address 15	mm (0.6 in.) 51 mm (2 in.)
Delivery address 51	mm (2 in.) 89 mm (3.5 in.)

NOTES:

• For best print quality, position margins no closer than 15 mm (0.6 in.) 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 may wrinkle during printing. See "Printing on Envelopes" on page 3.14.

Labels

CAUTIONS:

• To avoid damaging the printer, use only labels recommended for laser printers.
• To prevent serious jams, always use the Multi-Purpose Tray to print labels and always use the rear output tray.
• Never print on the same sheet of labels more than once and never print on a partial sheet of labels.

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 (.5 in.) of curl in any direction.
• Condition: Do not use labels with wrinkles, bubbles, or other indications of separation.

See "Printing on Labels" on page 3.17.

Transparencies

Transparencies used in the printer must be able to withstand 170 °C (338 °F), the printer's fusing temperature.

CAUTION: To avoid damaging the printer, use only transparencies recommended for use in laser printers.

See "Printing on Transparencies" on page 3.19.
