Action
Turn printer off and remove the print
cartridge and left side cover.
With a left finger, rotate the main
motor counterclockwise while using
a right finger to resist gear
movement in the plate assembly
(reference edge) in the paper path
below the cartridge.
If the gear motion can be stopped
while continuing to rotate the drive
motor, one of the units has to be
replaced. The paper feed gear is
most likely the failing part.
Remove the drive assembly for
further inspection. Replace the faulty
unit.
When the plate assembly is
replaced, it has to be adjusted. See
"Adjusting Paper Feed
Alignment" on page 4-3
