2. OPERATION DESCRIPTION
2.1 Electrophotographic Process Mechanism
(1) Electronic photography Process
Electronic photography process is outlined as follows:
1. Electrification
Electric voltage is impressed on CH roller and the surface of CPC drum is electrified.
2. Exposure
LED head radiates light on the electrified surface of OPC drum following the image
signal. Electric charge on the radiated OPC drum surface abates depending on the
intensity of light and static latent image is formed on the OPC drum surface.
3. Development
Electrified toner is adhered to the static latent image on the OPC drum by static electric-
ity and a visible image is formed on the OPC drum surface.
4. Transcript
A sheet of paper is put upon the OPC drum surface and the toner image is transferred
on the paper by impressing electric charge on its back side by the transcript roller.
5. Drum Cleaning
Drum cleaning blade eliminates the remaining toner on the OPC drum after transfer.
6. Belt Cleaning
Belt cleaning blade eliminates the remaining toner on the belt.
7. Fusing
The toner image on the paper is fused by adding heat and pressure.
(2) Electrification
Electric voltage is impressed on electrification roller touching on the OPC drum surface and
thus the OPC drum surface is electrified.
