  • Page 20: Explanation Of Operation

    Oki Data CONFIDENTIAL EXPLANATION OF OPERATION Electrophotographic processing mechanism 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 21 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 24 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 25: Printing Process

    Oki Data CONFIDENTIAL Printing process The paper fed from Tray 1 or Tray 2 is carried by the paper feed roller, register roller L and transport roller. When the paper is fed from the MPT, it is carried by the MPT paper feed roller and register roller U.
  • Page 26 Oki Data CONFIDENTIAL Paper fed from 1st Tray 1. As illustrated in Figure 2-1, when the solenoid is ON, the register motor rotates (Counterclockwise turn), transporting the paper until the IN1 sensor comes ON. (When the solenoid is ON, the paper feed roller is driven.) 2.
  • Page 27 Oki Data CONFIDENTIAL (3) Transport belt 1. As the transport belt motor rotates in the direction of the arrow, the transport belt is driven. The belt unit consists of one transport roller placed immediately underneath each color drum, with a transport belt inserted in between them.
  • Page 28 Oki Data CONFIDENTIAL Up/down-motions of ID units 1. The up/down-motions of the ID units take place driven by the lift-up motor. 2. Figure 2-6 shows the motions of the different ID units when the printer is operated for color print. As the lift-up motor rotates (Clockwise turn), the lift-up link slides to the left, causing the ID units to come down, as can be seen in Figure 2-6.
  • Page 29 Oki Data CONFIDENTIAL Fuser unit and paper output 1. As illustrated in Figure 2-8, the fuser unit and delivery roller are driven by the DC motor. As the fuser motor rotates (Counterclockwise turn), the heat roller is turned. This roller fixes a toner image by heat and pressure.
