Tips on preventin g 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 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
– Use 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
current printing environment.
