    Oki Data CONFIDENTIAL 2. OperatiOn DescriptiOn 2.1 Electrophotographic Process Mechanism (1) Electronic photography Process Electronic photography process is outlined as follows: 1. Electrification Electric voltage is impressed on CH roller and the surface of CPC drum is electrified. 2. Exposure LED head radiates light on the electrified surface of OPC drum following the image signal.
  • Page 17 Oki Data CONFIDENTIAL (3) Exposure The light emanated from the LED head is radiated on the OPC drum surface. The electric charge on the radiated portion of the OPC drum surface abates by intensity of the light and a static latent image is formed on the OPC drum surface.
  • Page 18 Oki Data CONFIDENTIAL (5) Transcript A sheet of paper is placed under the OPC drum surface and is given electric charge from the back side by the transcript roller. When a high voltage is impressed on the transcript roller, the electric charge generated by the transcript roller moves over to the paper surface at the interfacing part of the transcript roller and the toner is absorbed to the paper surface from the OPC drum surface.
  • Page 19 Oki Data CONFIDENTIAL (6) Fusing The toner image transferred on the paper is impressed with heat and pressure and is fused to the paper when the paper passes through the heat roller and the back-up roller. Further, a thermostat is equipped for the safety’s sake and if the temperature of the heat roller rises above a certain degree, the thermostat opens and shuts the power supply to the heater.
