14-2. Image Transfer/Paper Separator Corona Wires Cleaning Mechanism
The Image Transfer/Paper Separator Coronas are provided with a mechanism that
automatically cleans its corona wires. It effectively removes from the wires any toner
and dust particles which would otherwise cause uneven charging, white streaks on
copies, and charge leak.
<Mechanism>
When Image Transfer/Paper Separator Charge Wire Cleaning Motor is energized,
its drive is transmitted to the Screw Shaft. This in turn moves the two Cleaners
mounted on the Screw Shaft.
Image Transfer/Paper Separator Wire Cleaning Motor is a two-phase stepping
motor. The Cleaners are detected at their home position (which is the reference
position for the cleaning motion) by Transfer/Separator Wire Cleaner Home Position
Sensor.
The Cleaners make one round trip per each cleaning cycle.
