Electrophotographics system

Electrophotography is the technology used in laser printing which transfers 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.
The key features for the electrophotography system of the printer are:
• Real 600 dpi resolution (equivalent to 2400 dpi resolution thanks to KIR smoothing
technique)
• Ultra long life amorphous silicon drum (non-heating)
• Paper support for up to A3 (Ledger) size
• Microfine mono component toner

Electrophotographic cycle

The electrophotography system of the printer performs a cyclic action made of seven steps
as follows. Each step is technically explained in the following sections.
2 Exposure
1 Main Charging
7 Erasing 3 Developing
6 Cleaning
4 Transfer
5 Fusing
