Xerox WorkCentre 6655

Purpose

This procedure explains how to check the operation of the Dispenser Motors and related gears. This is typically done when an error is caused from an amount of toner in the Imaging Unit’s developer assembly that is insufficient to maintain density. The two likely causes are, the Print Cartridge is not fully seated, or the replenisher assembly is not functioning correctly.

Procedure

1. Enter Service Diagnostics, GP 1.
2. Select the Service Info tab.
3. Select dC330 Component Control.
4. Remove the affected toner cartridge (e.g., Cyan)
5. Select code 041-001 for the 24V low voltage power supply.
6. Select the code for an unaffected toner dispenser motor (e.g., Yellow: 93-004) and listen to the gear movement. It should be smooth and relatively quiet. You can also look at the toner gear movement on the left side of the machine where the toner is dispensed.
7. Turn off the unaffected toner dispenser motor (e.g., Cyan: 93-008).
8. Turn on the affected toner dispenser motor and listen to, or watch, the gear movement. If there is clicking or chattering, the problem is related to the toner dispenser assembly
9. Turn off the affected toner dispenser motor and the low voltage power supply.
10. Select Close to exit the routine.
11. Select Call Closeout to exit Service Diagnostics.
