7.6 Drum Cleaner Unit

7.6.1 Outline

iR7105 / iR7095 / iR7086
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.
The blade vibration unit is driven for the following:
- after initial multiple rotation imitated by turning on the main power (5 or 1 vibration)
- at time of STOP sequence (1 vibration)
- during wire cleaning associated with pre-transfer, transfer, and separation (1 vibration)
1 vibration: ON for 0.6 sec
5 vibrations: ON for 0.6 sec, OFF for 0.3 sec
SERVICE MODE:
You can check the activation of the blade vibration unit in service mode: COPIER>FUNCTION>PART-CHK>MTR.
