4.7 Energy Drive Roller
Maintenance Schedule
Clean every 750K cycles.
Procedure
Reference Figure 4.33 Energy Roller as you perform this procedure.
1. Without disconnecting either retaining spring (1), roll one of them gently to one
side to release the Energy Drive Roller shaft from its mounting bracket.
2. Lift the shaft (2) from the mounting bracket.
3. Using a clean cloth and alcohol, clean the surfaces of the rollers (3) to remove
any paper dust or toner that may have accumulated over time.
4. Reverse steps 2 & 1 above to replace the shaft into the holder.
5. Ensure the flats of the bearings are seated properly in the mounting brackets.
6. Ensure the springs are straight on the bearing to apply sufficient force for the
rollers to turn when you rotate the knob at the front of the machine.
