(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.
(1) Photoconductor
• This model uses OPC (organic photoconductor) as photoconduc-
tive material. (
