Media jams and the paper path
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.
2.
Inspect the paper for bent, torn or folded corners. Check for stuck
sensor flags.
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 indicate 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. Refer “Specifications”
on page 24 or the built-in embedded page, “Paper Tips.”
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. In humid environments, keep media sealed in packaging until it is
needed for printing. Flip over the media in the tray
2.
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.
3. Clean the interior of the media tray. When installing paper, push down
the stack of paper until the tray's lift-plate locks to the bottom of the
tray. This prevents the top sheet of paper from being mis-positioned as
the tray is inserted in the printer.
4.
Hi-Capacity Paper Tray Assembly.
Ensure the pick roller is installed
correctly. (It can inadvertently be installed backwards.)
