6.8.5 CHARGE CORONA WIRE CLEANING

[C]
[B]
Air flowing around the charge corona unit deposits toner particles on the wires.
These particles interfere with charging and cause pale bands on copies.
The wire cleaner [A] normally remains at the home position at the front end.
To clean the wires, the charge corona wire cleaner motor [B] switches on and
drives the cleaner [A] to the rear, then back to the home position.
The wire cleaner rotates slightly on the forward pass to bring the cleaning pads [C]
into contact with the wires. Cleaning is done only on the forward pass. The pads do
not contact the wires on their return to home position.
The motor [B] switches on after the machine is switched on, but only after 5,000 or
more copies have been made since the last wire cleaning.
