Toner
Cartridge
Separation
The toner cartridge separates from the photosensitive drum after the
development process.
After the developing cylinder ceases to rotate, the mechanical
controller reverses the toner carousel motor. This motor drives the
operation of the cartridge press cam so that the pressure on the press
actuator is released and the toner cartridge separates from the photosen-
sitive drum. When the press cam is about to turn, the controller sets the
developing rotary brake signal (
/DEVBRK) to “H” and turns the toner
carousel brake clutch (CL1) off. When the toner cartridge position
sensor (PS3) detects the cartridge has begun to leave the drum, the
controller sets
/DEVBRK to “L” and CL1 to on again, and stops the toner
carousel motor.
