Tips for successful printing

Tips on storing print media

Store your print media properly. For more information, see Storing print media.

Avoiding jams

If you select appropriate print media (paper, transparencies, labels, and card stock) for your printer, you’ll be well on your way to trouble-free printing. See Print media guidelines for more information.

Note: We recommend that you try a limited sample of any print media you are considering

using with the printer before purchasing large quantities.

By carefully selecting print media and loading it properly, you should be able to avoid most jams. See the following for instructions on loading print media:

• Loading trays (including the standard tray, optional 250-sheet tray, and optional label tray)

• Loading the optional 500-sheet tray

• Using and loading the multipurpose feeder

If you do experience a jam, see Clearing jams for instructions.

The following hints can help you avoid jams:

• Use only recommended print media. See Print media guidelines for more information. Refer

to the Card Stock & Label Guide available on Lexmark’s Web site at www.lexmark.com/ publications for more information about which print media will provide optimum results for your printing environment.

• If you need detailed information before purchasing large quantities of customized print media,

refer to the Card Stock & Label Guide.

• Do not load wrinkled, creased, damp, or curled print media.

• Flex, fan, and straighten print media before you load it. If jams do occur with print media, try

feeding one sheet at a time through the multipurpose feeder.

• Do not overload the print media sources. Make sure the stack height does not exceed the

maximum height indicated by the labels in the sources.

• Do not use print media that you have cut or trimmed yourself.

• Do not mix print media sizes, weights, or types in the same print media source.

• Make sure the recommended print side is face down when loading all trays and the

recommended print side is face up when loading the multipurpose feeder.

• Keep print media stored in an acceptable environment. See Storing print media.

• Do not remove trays during a print job.

• Push all trays in firmly after loading them.

• Make sure the guides in the trays are properly positioned for the size print media you have

loaded. Make sure the guides are not placed too tightly against the stack of print media.

• Card stock must exit to the rear output bin. See Using the rear output bin for more

information.

• Envelopes may be sent to the standard output bin; however, if the envelopes exit to the rear

output bin there is less curl.

• Make sure all cables that connect to the printer are correctly attached. Refer to the Setup

Guide for more information.

Storing print media

Use the following guidelines for proper print media storage. These help avoid paper feeding problems and uneven print quality:

• For best results, store print media in an environment where the temperature is approximately

21°C (70°F) and the relative humidity is 40%.

• Store cartons of print media on a pallet or shelf, rather than directly on the floor.

• If you store individual packages of print media out of the original carton, make sure they rest

on a flat surface so the edges do not buckle or curl.

• Do not place anything on top of the print media packages.

Clearing jams

By carefully selecting print media and loading it properly, you should be able to avoid most jams. If jams do occur, complete the steps in the following sections. If jams occur frequently, see Avoiding

jams.

Note: To clear the Paper Jam error light message, you must remove all jammed print

media from the entire paper path. Press and release the Continue button to clear the message and resume printing. A new copy of the page that jammed prints if Jam Recovery is set to On in the printer driver or in the Local Printer Setup Utility. Setting Jam Recovery to Auto does not guarantee that a new copy of the page will print.

The following illustration shows the path that print media travels through the printer. The path varies depending on the input source (trays and multipurpose feeder) and output bin you are using.

Jams under the print cartridge

Since the jam may occur farther back in the printer behind the print cartridge area, you may need to reach in farther to remove the jam.

1 Open the upper front door. 2 Remove the print cartridge. (See Removing the used print cartridge for instructions.)

CAUTION: The rear portion of the inside of the printer may be hot.

Note: The ends of the print media may not be visible.

With both hands, pull the print media to the right, and then out.

Note: If the print media resists, stop pulling and access it from the rear output bin door.

See Jams behind the upper front door and the rear output bin door to continue.

4 Reinstall the print cartridge. (See pages 72 through 73 of Installing the new print cartridge

for instructions.)

5 Close the upper front door.

Jams behind the upper front door and the rear output bin door

Jams in these areas require opening the rear output bin door and the upper front door:

• The print media jams before reaching the standard output bin. See Before reaching the

standard output bin.

• The print media jams before exiting completely into the standard output bin. See Exiting to

the standard output bin.

Before reaching the standard output bin

The print media jams before reaching the standard output bin.

1 Open the rear output bin door.

Gently remove the jam based on how much is visible.

• If the middle of the sheet of print media is visible, but not the ends, grasp the print media on

both sides and gently pull it straight out toward you.

• If an end of the jam is visible, pull it straight out toward you.
