7.6 Drum Cleaner Unit

7.6.1 Outline

The following shows the components of the machine's drum cleaner unit:
The presence of a cake of toner on the cleaning blade inside the cleaner unit is likely to prevent normal
cleaning of the drum, and the machine uses 2 blade vibration units to prevent adhesion of toner. When
these units vibrate, the entire blade will vibrate to shake off the toner, thereby eliminating cleaning faults
otherwise caused by cakes of toner.
