Tips on preventing jams
You can avoid most paper jams by correctly loading paper andspecialty 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 firmlyinto the printer after loading them. Make sure the guides in the trays are positioned snugly againstthe paper or specialty media.
Do not remove paper trays while a job is printing. Wait for aLoad Paper light sequence before you remove the tray.
Before loading transparencies, fan the stack to prevent sheetsfrom 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
