7-1. PC Drum Charge Corona Comb Electrode Cleaning Mechanism

The two PC Drum Charge Corona Comb Electrodes are provided with a cleaning

mechanism that removes from the electrodes any toner and dust particles which

would otherwise cause uneven charging, white streaks on copies, and charge leak.

When PC Drum Charge Comb Cleaning Motor M7 is energized, its drive is trans-

mitted to the Screw Shaft. This in turn moves the Cleaner mounted on the Screw

Drum Comb Cleaner Home Position Sensor PC16 detects the Cleaner at its

home position (which is the reference position for its cleaning motion). The

Cleaner makes one round trip per each cleaning cycle to clean the electrodes.
