(4) Copy process

This model basic process and structure

The Scorotron method is used to evenly charge the photoconduc- tor surface to the given potential in the charge process. The corona wire regularly used is now replaced with a new corona charge mechanism that employs the 0.1mm thick stainless steel saw teeth plate, in order to suppress ozone generated when the oxide molecule in air is ionized.

Considering the service efficiency, the process separation mechanism is adopted.

To prevent high voltage leakage by the loose corona charge unit, a one-touch stopper mechanism is adopted.
