“Main drive service check” on page 2-105
.
Autocompensator fails to feed paper. Failures occur randomly throughout the stack
of paper
Paper feed failures occur only near the top of the stack of paper
The most common cause of this problem is paper curl. Remove the paper from tray
x
and check for the natural
curvature in the paper. Reinstall the paper in the correct manner. If the problem persists, it may be necessary to
reduce the stack height. Replace both pick rolls if the paper appears to be flat in the tray but there is still a
problem.
Failures occur mainly near the bottom of the stack of paper
The autocompensator pick arm may not be coming down far enough to allow the pick rolls to properly contact
the paper. Also the autocompensator motor may be failing. If this problem continues replace the
autocompensator assembly.
Double feeding paper
Note:
If double feeding paper occurs mostly from the bottom of the stack, check for missing or damaged
restraint pads in the tray.

Paper
Paper is usually the primary cause of a double feeding paper
problem. Flex the paper before placing the paper in the tray. Edge-
welded paper is the most common cause of double feeding. Loading
the paper in the tray in different locations and directions and using
rough paper and short grain paper also causes double feeding.

at the top of the autocompensator arm assembly. If you find a
problem, replace the autocompensator assembly.
