TABLE
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 “8. PC DRUM”.)
2. Drum Charging
The PC Drum Charge Corona Unit is equipped with a Comb Electrode and a Scorotron Grid to
deposit a uniform negative charge across the entire surface of the PC Drum.
(For more details, see “9. DRUM CHARGING”.)
3. Image Erase
Any areas of charge which are not to be developed are neutralized by lighting up LEDs.
(For more details, see “10. IMAGE ERASE LAMP”.)
4. 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 “11. OPTICAL SECTION”.)
5. Developing
Toner positively charged in the Developer Mixing Chamber is attracted onto the electrostatic
latent image changing it to a visible, developed image. A DC negative bias voltage is applied
to the Sleeve/Magnet Roller to prevent toner from being attracted onto those areas of the PC
Drum which correspond to the background areas of the original.
(For more details, see “13. DEVELOPMENT”.)
