Clearing Jams
Guide
Avoiding jams
The following hints can help you avoid paper jams:
•Use only recommended paper. Refer to the
Card Stock & Label Guide available on the
Lexmark Web site at www.lexmark.com/
publications for more information about which
paper provides optimum results for your printing
environment.
•Do not remove paper trays while a job is
printing. Wait for a Load Tray <x> or Ready
message before you remove the tray.
•If you need detailed information before
purchasing large quantities of customized
paper, refer to the Card Stock & Label Guide.
•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 overload the trays or the multipurpose
feeder. Make sure the stack height does not
exceed the maximum height indicated.
•Push all trays firmly into the printer after loading
them.
•Make sure the guides in the trays are properly
positioned for the size paper you have loaded.
•Do not send jobs to staple, hole punch, or offset
for transparencies, labels, or card stock.
•We recommend that transparencies, labels,
card stock, and envelopes not be sent to the
optional mailbox or optional finisher. These
specialty media types should be sent to the
standard bin.
•If a jam should occur, clear the entire paper
path.
