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.

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.

SERVICE MODE:

These settings may be changed in service mode to suit the site of installation: COPIER> OPTION> BODY> VBR-M-SW.

The operation of the blade vibrating units may be checked in service mode: COPIER> FUNCTION> PART-CHK> MTR.
