Required tools
TORX screwdriver and tips
Digital multi-meter
Jams fall into the following four categories:

Media-based problems

Paper-pick errors

Paper-feeding errors
Paper-ejecting errors
Media-based problems
1.
Check that the correct type of media is being used. Fanning the media
eliminates its tendency to double-pick.
2.
Inspect the paper for bent, torn or folded corners.
3.
Check to ensure no small pieces of paper are in the paper path.
4.
Ensure that the correct media is in the correct media tray. The tray
switch actuators indicates the size and the type of media loaded in the
tray; the printer does not directly sense the size or type of media.
5.
Ensure the correct weight of paper is being used. Use 16 - 32 lb. Bond
(60 - 120 g/m
Bond (60 - 120 g/m
6.
Ensure that envelopes are of the acceptable size and orientation with
the side-flap up.
Paper-pick errors
Paper-pick errors occur when the media in the media tray mispicks or the printer
double-picks two or more sheets of paper.
1.
Fan the media before inserting it in the media tray.
2.
In humid environments, keep media sealed in packaging until it is
needed for printing.
3.
Ensure that the media fits properly in the tray. With the left edge of the
stack of paper flush against the tray rail, there should be a small gap
between the opposite edge of the stack of paper and the opposite side
rail.
4.
Clean the interior of the media tray. When installing paper, push the
stack of paper down until the tray's lift-plate locks to the bottom of the
tray. This prevents the top sheet of paper from being mispositioned as
the tray is inserted in the printer.
