5.7 Preventing Adhesion of Toner to the Cleaning Blade

The presence of caking toner on the cleaning blade inside the cleaner unit can adversely
affect the cleaning of the drum. To prevent caking of toner, the blade of the machine is
equipped with 2 blade vibrating units, which vibrate the blade to break and drop cakes of
toner, thus preventing drum cleaning faults.
Blade vibration unit
The blade vibrating units go ON as follows:
• after initial multiple rotation at time of main power-on (5 times or once)
• at stop sequence (once)
• when cleaning wire (pre-transfer, transfer, separation; once)
When vibrating once, it remains ON for 0.6 sec.
When vibrating 5 times, it remains ON for 0.6 sec and OFF for 0.3 sec.
