WASTE TONER NEAR-FULL/FULL DETECTION CONTROL
 Waste Toner Detection Mechanism
 To prevent false detection, an Agitation Screw is mounted in the Waste
Toner Collector so that the waste toner is accumulated in the bottle
evenly.
 The Waste Toner Full Sensor (PC8) detects the area where the visor A
mounted on the shaft of the Toner Conveying Screw overlaps with the
visor B. (As the amount of the waste toner increases, the load for the
screw to rotate will increase. The period of time the Light Shield Plate
blocks the Waste Toner Full Sensor (PC8) will then become shorter).
