11.7 Charger Wire Cleaner

11.7.1

Operation

This equipment includes an automatic cleaning function with a motor drive to automatically clean off the
toner adhered on the charger wire. The drive from charger cleaner motor (M13) is transmitted to the
wire cleaner through the timing belt and the wire cleaner contacted by the charger wire shuttles
between the both ends of charger wire. The waiting position (home position) of the wire cleaner is at the
front side. The wire cleaner and charger wire are not contacted each other at the waiting position.
The cleaning movement is performed in the cases as follows:
1) When the power is turned ON
2) When recovered from the energy saving mode
3) When opening/closing the front cover
4) When the specified number of pages has been printed out (default value: 1,000 pages) from the last
cleaning (If the number of pages has reached the setting value during continuous printing, the clean-
ing movement is performed upon the completion of this printing job.)

Construction

1) Charger cleaner motor (M13)
This motor is a DC brush motor and supplies the drive to the wire cleaner. When the motor rotates in
reverse, the wire cleaner shifts to the rear side. Also when the motor rotates normally, the wire
cleaner shifts to the front side.
2) Charger cleaner front position detection switch (S25)
This switch detects whether the wire cleaner has reached to the front position (home position) or
not.The wire cleaner is always waited at this position except during cleaning movement.
3) Charger cleaner rear position detection switch (S26)
This switch detects whether the wire cleaner has reached to the rear position or not. When this
switch is turned ON, the charger cleaner motor (M13) rotates normally. Then the wire cleaner shifts
to the front position (home position).
