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 right 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.
5. Check that the pick roller is being rotated. In its starting
position, the pick roller’s flat side should face down; the flat,
keyed end on the left end of the pick roller shaft faces up. If it
is not, proceed to the topic “Checking the process motor and
drive train.”
6. Clean the pick roller with alcohol and a lint-free cloth. Paper
dust can coat the pick roller and affect its ability to grip the
paper and pull it out of the tray. Also clean the transport
rollers.
7. Use the PC-based diagnostic’s “Verify Drive Current
Requirements” test to check the operation of the paper-pick
system.
8. Inspect the wiring harness leading to the paper transport
clutch for nicks, cuts or crimped wiring. Ensure the connector is
seated.
9. Inspect the paper-feed path for obstructions.
Print Transfer Jams
1. Using PC diagnostics, test the paper preheater. If the test fails,
replace the paper/drum heater assembly.
2. Check to see if the upper feed roller drive belt is broken or
slipped off of its pulleys. In such a case, the upper feed roller
does not rotate when the lower feed roller rotates.
3. Check that the feed rollers rotate smoothly and that the front
cover is fully closed and seated.
