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 the 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 problems continues,
replace the autocompensator assembly.
