Change: New drum cleaning unit
Reason: To prevent SC39x (drum lock) caused by a toner blockage between the cleaning
brush and the toner collection coil
Following are the improvements made to the new drum cleaning unit (M0773602) installed
with a new agitator (M0773674).
- Higher performance of the agitator prevents toner from overflowing and generating
printouts stained with toner.
- Higher performance of the agitator prevents toner clumps from forming at the
aperture, which can break the gear or completely disable the drum cleaning
operation.
