2-1-3 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 machine's electrophotography system.

(1) Electrophotographic cycle

The electrophotography system of the machine 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.
