Tips on preventing jams
You can av oid most paper jams by correctly loadi ng paper and specialt y
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 posi ti oned 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 or message before you remove the
tray.
• Before l oading transparencies, fan the stack to prevent sheets fr om
sticking together.
• Do not use envelopes that:
– Have excessive curl
– Ar e stuck together
– Ar e dam aged in any wa y
– Co ntain windows, holes, perforations, cutouts, or embossing
– Have metal clasps, string ties, or metal folding bars
– Have postage stamps attached
