Outline; Developing Assembly/Drum Cleaner - Canon NP6330 Service Manual

II. DEVELOPING ASSEMBLY/DRUM CLEANER
A. Outline
The copier is designed in such a way so that its developing assembly is manually
locked/released together with its rail when a locking lever is operated.
The developing cylinder, the toner stirring roller inside the developing assembly, and
the blade inside the drum cleaner are rotated by the drive of the main motor (M1).
The level of toner remaining inside the developing assembly is monitored by a toner
sensor (TS1).
The waste toner gathered by the cleaning blade is collected inside the drum cleaner
container.
The copier is equipped with a torque limiter in its photosensitive drum drive
assembly. When an excess load is imposed on the photosensitive drum while the
photosensitive drum is rotating (as when the case becomes full of waste toner), the drive
from the main motor will be cut off to stop the rotation of the photosensitive drum.
Reference:
The copier does not have a mechanism to detect the level of waste toner inside the
drum cleaner. As a guide, keep in mind that the waste toner case becomes full
when about 60,000 copies (same as drum life) have been made of 6% duty
originals.
