17-3. Image Transfer/Paper Separator Corona Wires Cleaning
Mechanism/Control
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.

•
When Image Transfer/Paper Separator Charge Wire Cleaning Motor
M22 is energized, its drive is transmitted to the Screw Shaft. This in turn
moves the two Cleaners mounted on the Screw Shaft.
•
M22 is a two-phase stepping motor. The Cleaners are detected at their
standby position (which is the reference position for the cleaning motion)
by Transfer/Separator Wire Cleaner Home Position Sensor PC55.
•
The Cleaners make one round trip per each cleaning cycle.
