Fuser Hot Rollers
See Assembly 32-12, 32-13.
1. Remove the fuser assembly.
2. Place the fuser on a flat surface.
Note: Do not tilt the fuser. It contains oil that can spill.
3. Follow the steps in the Fuser Lamps Removal procedure and
remove the lamps.
4. Remove the fuser oil apply assembly.
5. Remove the screws from the HV mount located at the rear left
corner of the fuser and remove the mount.
Note: Do not remove the brown gear mounting bracket. If the
bracket is removed for another reason (such as a broken gear), the
bracket is difficult to reinstall. The reduced diameter end of the shaft
engages a hole in a floating inner plate. This provides proper hot roll
pressure engagement. To check for proper installation of this
bracket, view the fuser from the input side. The bracket must be ver-
tical. The side play of the brown gear is minimal when the bracket is
properly installed.
6. Remove the screw from the lower hot roller grounding terminal
located at the front of the fuser and remove the terminal and
grounding ring.
7. Remove the grounding ring from the rear of the upper hot roller.
8. Remove the four outer grip rings from the hot rollers (one on
each end of the rollers).
9. Slide the gear and bearings off the upper hot roller and remove
the roller.
10. Using a grip ring pliers, slide the grip ring on the rear of the
lower hot roller back far enough to allow the bearing to clear the
plate and remove the lower hot roller.
Note: During reassembly the hot roller pressure springs have to
compressed slightly to allow the insertion of the upper hot roller. To
do this place a screwdriver blade between the fuser delivery assem-
bly mounting pins and the lower hot roller bearing mounting plates.
