Tips on preventing jams

You can avoid most paper jams by correctly loading paper and specialty media.

The following hints can help you avoid paper jams:

•Do not load wrinkled, creased, or damp paper.

•Never mix media types within a tray.

•Flex, fan, and straighten paper before you load it.

•Do not exceed the maximum stack height.

•Push all trays firmly into the printer after loading them.

•Make sure the guides in the trays are positioned snugly against the paper or specialty media.

•Do not remove paper trays while a job is printing. Wait for a Load Paper or Ready light sequence before you remove the tray.

•Before loading transparencies, fan the stack to prevent sheets from sticking together.

•Do not use envelopes that:

–Have excessive curl

–Are stuck together

–Are damaged in any way

–Contain windows, holes, perforations, cutouts, or embossing

–Have metal clasps, string ties, or metal folding bars

–Have postage stamps attached

–Have any exposed adhesive when the flap is in the sealed position

•Use only recommended paper. Refer to the Card Stock & Label Guide available on the Lexmark Web site at www.lexmark.com for more information about which paper provides optimum results for the current printing environment.
