If the bin extender is longer than the size of the paper you are printing on, then the edges become
uneven and the paper is not stacked properly. For example, if you are printing on a letter-size paper
and the bin extender is set to legal-size, then the paper does not stack properly.
If paper needs to be returned to the mailbox bin, then insert the paper under the bin arm, and then push
the paper all the way back.
Note: If the paper is not under the bin arm, then a jam occurs due to an overﬁlled bin.
Use recommended paper
Use only recommended paper or specialty media.
Do not load wrinkled, creased, damp, bent, or curled paper.
Flex, fan, and straighten paper or specialty media before loading it.
Do not use paper that has been cut or trimmed by hand.
Do not mix paper sizes, weights, or types in the same tray.
Make sure the paper size and type are set correctly on the computer or printer control panel.
Store paper per manufacturer recommendations.
Identifying jam locations
When Jam Assist is set to On, the printer ﬂushes blank or pages with partial prints after a jammed page
has been cleared. Check your printed output for blank pages.
When Jam Recovery is set to On or Auto, the printer reprints jammed pages. However, the Auto setting
reprints jammed pages if adequate printer memory is available.
