2. At the job site, select a place that is as far as possible away from the users and that is
enclosed by walls.
3. Do not bring a highly reflective tool into the laser beam path during the service job.

8. Paper Feed
2. Drum Charging
•
A scorotron charger employing a comb electrode generates a negative DC charged
layer on the surface of the PC Drum.
3. Photoelectric Conversion Section
•
The Exposure Lamp directs light onto the original. The light reflected off the original is
directed and resized by the mirrors and lens so as to produce a reduced-size image on
the CCD Sensor.
4. HGB Board
•
Converts an electric signal into a corresponding 8-bit digital image signal (A/D conversion), makes various corrections, and outputs the results to the MFB Board.
5. MFB Board
•
Compresses the image data received from the HGB Board, stores it, and uncompresses it.
6. Laser Exposure
•
The laser beam emitted from the LD (laser diode) strikes the surface of the PC Drum,
creating an electrostatic latent image.
7. Development
•
Negatively charged toner adheres to the latent image on the PC Drum surface, creating
a visible image.
8. Paper Feed
•
Feeds sheets of paper from the appropriate paper source.
9. Image Transfer
•
An Image Transfer Roller is used. A positive charge applied to the roller causes the visible image on the surface of the PC Drum to transfer onto the front side of the paper.
M-2
10. Paper Separation
•
The PC Drum Separator Fingers remove paper from the surface of the PC Drum.
11. Cleaning
•
The Cleaning Blade scrapes residual toner off the surface of the PC Drum and the toner
is recycled back to the Developing Unit.
12. Erase
•
The PC Drum is exposed to light, which effectively removes any residual charge from
the drum surface.
13. Fusing
•
Heat and pressure applied by the Right and Left Fusing Rollers fuse toner on the paper.
14. Paper Exit
•
Feeds paper out of the copier.
