COPY PROCESS
1. PC Drum
The PC Drum is an aluminum cylinder coated with a photosensitive semiconductor.
It is used as the medium on which a visible developed image of the original is
formed.
(For more details, see p. M-25.)
2. Drum Charging
The PC Drum Charge Corona Unit is equipped with two corona wires and Scorotron
Grids to deposit a uniform negative charge across the entire surface of the PC
Drum.
(For more details, see p. M-28.)
3. Exposure
Light from the Exposure Lamp reflected off the original is guided to the surface of
the PC Drum and reduces the level of the negative charges, thereby forming an
electrostatic latent image.
(For more details, see p. M-34.)
4. Image Erase
Any areas of charge which are not to be developed are neutralized by lighting up
LEDs.
(For more details, see p. M-62.)
5. Developing
Toner positively charged in the Developer Mixing Chamber is attracted onto the
electrostatic latent image changing it to a visible, developed image.
(For more details, see p. M-69.)
6. Pre-Image Transfer Erase
Light from the Pre-Image Transfer Erase Lamp striking the surface of the PC Drum
improves image transfer and paper separation efficiency.
(For more details, see p. M-93.)
