    Oki Data CONFIDENTIAL OPERATION DESCRIPTION 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 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.

  • Page 21: Printing Process

    Oki Data CONFIDENTIAL Printing Process The paper feeded from tray 1 is transported by the resist roller L and transport roller. When the paper is feeded by the manual feeder, it is transported by the resist roller U. Then, the paper transported is developed into a toner image not yet fused on the paper through electronic photography process in the order of KYMC.
  • Page 22 Oki Data CONFIDENTIAL (1) Paper Feeding from the 1st Tray 1. As shown in Figure 2-1, while the solenoid is on and the resist motor turns counterclockwise, a sheet of paper is transported until the IN1 sensor is on. (When the solenoid is on, the paper feeding roller operates.)
  • Page 23 Oki Data CONFIDENTIAL (3) Transport Belt 1. When the transport belt motor turns in the direction of the arrow, the transport belt starts to operate. The belt unit is composed of drums of each color above and the transport rollers immediately below them with the transport belt in-between.
  • Page 24 Oki Data CONFIDENTIAL (4) Up and Down Movements of ID Units 1. The up and down movements of the ID units are performed by the drive of the lift-up motor. 2. Figure 2-5 shows movements of each ID unit at the time of printing. When the lift-up motor turns clockwise, the lift-up link slides to the left and each ID unit is in the state of down as shown in Figure 2-6.
  • Page 25 Oki Data CONFIDENTIAL (5) Fusing Unit and Paper Output 1. As shown in Figure 2-7, the fuser unit and output roller are driven by the pulse motor. When the fuser motor turns counterclockwise, the heat roller turns. This roller fuses the toner image ‘on the paper with heat and pressure.
