4069-XXX

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 problems 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.

1

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.

Autocompensator

Make sure the counterbalance

 

 

spring is not missing, loose or

 

 

broken at the top of the

 

 

autocompensator arm assembly. If

 

 

you find a problem, replace the

 

 

autocompensator assembly.
