4-1 Electrophotographic system

Electrophotography is the technology used in laser printing which transfer data representing texts
or graphics objects into a visible image which is developed on the photosensitive drum, finally
fusing on paper, using light beam generated by a laser diode.
This section provides technical details on the printer's electrophotography system.

4-1-1 Electrophotographic cycle

The electrophotography system of the printer performs a cyclic action made of six steps as follows.
Each step is technically explained in the following sections.
The sections for main charging, exposure (drum), developing, and cleaning are modularized in one
Process unit PU-42.
