  • Page 23: Explanation Of Operation

    Oki Data CONFIDENTIAL EXPLANATION OF OPERATION Electrophotographic processing mechanism (1) Electrophotographic process The electrophotographic process is explained briefly below: 1. Charging A voltage is applied to the CH roller to electrically charge the surface of the OPC drum. 2. Exposure The LED head radiates light onto the charged OPC drum in accordance with the image signal.
  • Page 24 Oki Data CONFIDENTIAL Exposure The light emitted from the LED head is radiated onto the charged surface of the OPC drum. The charge of the radiated part of the OPC drum attenuates according to the intensity of the light, forming an electrostatic latent image on the OPC drum surface.
  • Page 25 Oki Data CONFIDENTIAL Transfer A sheet of paper is placed over the OPC drum surface, and an electric charge is given to the paper from its back side by the transfer roller. When a high voltage is applied to the transfer roller from the power source, the charge induced...

  • Page 27 Oki Data CONFIDENTIAL Fuser The toner image which was transferred to the paper is applied heat and pressure as it passes between the heat roller and the backup roller, and it is therefore fused onto the paper. For the sake of safety, a thermostat is provided; it comes on to cut off the voltage supplied to the heater if the heat roller temperature rises above a certain preset temperature.

  • Page 28: Printing Process
