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 .

• N ever mix media types within a tray.

• Fl ex, fan, and straighten paper before you load it.

• Do not exceed the maximum stack hei ght.

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

• Make sure the gui des in the trays are positioned snugly against the

paper or specialty me dia.

• Do not remove paper trays while a job is printing. Wait for a Load

Paper or Ready light sequence or message before you remove the

tray.

• Before loading transparencies, fan the stack to prevent sheet s from

sticking together.

• Do not use envelopes that:

– Have excessive curl – Are st uck together – Are damaged in any way – Conta in wi ndows, holes , per forations, cutouts, or embossing – Have metal clasps, string ties, or metal folding bars – Have postage st am ps attached – Have any exposed adhesiv e when the flap is in the sealed posi ti on

• Use only recommended paper. Refer to the Card Stock & Label Guide

available on the Lexm ark Web site at www .lexmark.com for more information about whi ch paper pro vides opt im um result s for the curren t printing environment.
