6 Monitoring the Waste Toner Case
6.1 Outline
Waste toner is collected by the cleaning blade inside the drum, and is kept in the waste
toner assembly.
The waste toner inside the waste toner assembly is constantly stirred by the stirring rod
driven by the main motor. The tip of the stirring rod is equipped with a torque limiter unit,
which goes ON when the waste toner assembly becomes full and the rod can no longer
stir the waste toner; as a result, the sensor lever of the waste toner case full sensor
(PS120) will be pushed, causing the machine to know that the waste toner case has be-
come full.
