Drive Power
The Drive Power subsystem includes five motors and their driven assemblies.
■ Main Motor - The main motor provides the drive for paper feed, black developer
housing, and the fuser. The main motor gets 24 VDC power from the +24 Volt
power supply by way of the interface board. The motor enable and speed control
signals come from the microprocessor on the engine control via the interface
board.
■ Accumulator Belt Motor - The accumulator belt motor turns the drive roller for
the accumulator belt and the accumulator belt cleaner auger.
■ Transfer Roller Motor - Engages and retracts the transfer roller.
■ Developer Motor - The developer motor provides the drive for the C, Y, and M
developers.
