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.
Multipurpose Tray
Paper fails to feed from the multipurpose tray.
The pick roll should make one complete revolution and stop with the
flat side down. If the pick roll turns but does not pick paper, check the
roll for signs of wear, oil or grease on the surface of the pick roll or
slick spots. If you find a problem, replace the pick roll assembly.
Check to ensure the media that is being fed through the
multipurpose tray assembly meets recommended paper
specifications.
FRU Action
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.
2 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.
