6.8 DRUM CHARGE
6.8.1 OVERVIEW
This copier uses a drum charge roller to charge the drum.
The drum charge roller [A] contacts the surface of the drum [B] to give it a negative
charge. The high voltage supply board [C] supplies a negative dc voltage to the
drum charge roller through the charge roller terminal [D], bias plate [E], and the
rear roller bushing [F] to give the drum surface a negative charge of –950V.
