Drive and Pressure Roll Replacement
After prolonged use, the drive roller or pressure roller may develop flat areas,
which will impede consistent media travel. When this occurs, the roller will require
replacement. The following procedures explain how to remove and replace the
drive roller and pressure roller.
Tools Needed
#1 Phillips Screwdriver
3/32” Allen Wrench
1/8” Allen Wrench
Drive Roll Replacement
Turn the printer off and unplug the AC power cord. Lift the printer’s side cover.
Remove any media that may be exiting over the drive roller.
Flip the drive roll cam up to relieve pressure on the roller.
Remove the two outside screws from the shaft end plate at the end of the drive
roll shaft.
Slide this end plate and shaft assembly away from the frame plate. A 3/4” cup
washer will drop down as this assembly is pulled away from the side plate.
Turn the drive roller until the cap screw located on the inside of the roller close to
the main plate is visible from the front of the printer. Loosen but do not remove the
set screw with a 3/32” Allen wrench. Turn the roller to loosen the second set screw
in the same location.
Slide the drive roll away from the main plate until it drops down.
Insert the new drive roll so the set screw is over the flat of the coupling shaft.
Tighten the set screw lightly.
Re-install the shaft end plate and shaft assembly back through the frame plate
and into the bearing of the drive roll. Slip the cup washer over the plate shaft just
before inserting it into the drive roll bearing. The cup must face away from the
bearing surface as illustrated.
Secure the shaft end plate with the two mounting screws.
