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. For more information, see Clearing the
entire paper path.
