- Toner Dispense Mechanism
The toner in the toner cartridge goes through the following steps before reaching the developer.
Once the toner cartridge is set and the lever is moved toward the lock position, the JOINT ASSY
DISP and the toner cartridge shutter move frontward, opening the toner supply port.
The toner supplied from the toner cartridge is carried toward the developer by the Auger in the
HOUSING ASSY AUGER.
The Auger is a spiral-shaped part that carries toner forward as it rotates driven by the Dispense
Motor in the FRAME ASSY MOT.
After being carried to the front side of the HOUSING ASSY AUGER, the toner is fed to the devel-
oper via the port of the HOUSING ASSY AUGER.
