(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.

This model uses OPC (organic photoconductor) as photoconduc-
tive material. (φ50 mm)
