5045-001 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 vertical. 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 assembly mounting pins and the lower hot roller bearing mounting plates. Repair Information 4-31
