Theory of Operation
Toner Collection
Waste Toner Bottle Full Sensor (PL8.2.3)
The Waste Toner Bottle Full Sensor detects whether the Waste Cartridge is full. The
top of the Waste Cartridge is transparent, and that portion acts as an Actuator
which blocks light to the Sensor. As waste toner accumulates, the transparent
actuator section will eventually become opaque due to the waste toner. Therefore,
when the Sensor becomes blocked, a Full state is detected.
Waste Toner Bottle Position Sensor (PL8.2.4)
The Waste Toner Bottle Position Sensor detects whether the Waste Cartridge is
installed.
Note
Toner Waste Cartridge exists: Sensor blocked
Agitator Motor (PL8.2.7)
The Agitator Motor drives the Auger and Agitator that transports waste toner.
Auger Lock Sensor (PL8.2.16)
The Auger Lock Sensor detects a Stalled state of the Agitator Motor through the
half-crescent Actuator that moves in tandem with the shaft driven by the Agitator
Motor.
Waste Cartridge (PL8.2.19)
The Waste Cartridge collects waste toner.
