the wires are good, replace the Cartridge Motor (Y).
Check the Coupling and Spring

NOTE: The Dispense Motor is only energized for 10 seconds each time Start is pressed.
The display will indicate Off when the 10 seconds have expired. Pressing Start will ener-
gize the Dispense Motor for another 10 seconds. Press Start as often as necessary to get
an accurate reading.
Enter dC330 009-032 Dispense Motor Y. Press Start. Watch the Dispense and Conveyor
Gears to see if they rotate. The Toner Dispense Motor (Y) operates.
