2-1-2 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.
(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.
