Cleaning The Transfer Charging Wire - Canon NP6330 Service Manual

I. Cleaning the Transfer Charging Wire
1. Outline
The machine is equipped with an automatic cleaning mechanism for the transfer
charging wire which turns on under the following conditions:
At power-on, if the fixing temperature is 100°C or less.
Last rotation at each cumulative count of 500.
When charging wire cleaning (U25) is executed in user mode.
2. Operation
The charging wire is cleaned by moving the wire cleaner back and forth by the
cleaner motor (M11).
When the wire cleaner mount turns on the wire cleaner rear position switch (MSW2)
located at the rear of the charging assembly, the cleaner motor starts to rotate in reverse
until it reaches the wire cleaner home position switch (MSW1) located at the front of the
charging assembly. (The wire cleaner makes a single round trip in about 30 sec.)
If the switches are not turned on within a specific period of time, the DC controller will
stop the cleaner motor and, at the same time, will indicate 'E060'.
