Charge Corona Wire Cleaning
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.
