  • Page 16: Operation Description

    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 (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. LED head Electrified roller Power...
  • Page 18 (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 (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 20 (7) Drum Cleaning The toner not transferred and remaining on the OPC drum is scraped away by the drum cleaning blade and is collected in the waste toner area of the toner cartridge. Waste toner area Toner cartridge ID unit Drum cleaning blade (8) Belt Cleaning The toner remaining on the transcript belt is scraped away by the belt cleaning blade and is...

  • Page 21: Printing Process

    2.2 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 (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.) 2.
  • Page 23 (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. When a certain voltage is impressed, the transport belt and the transport rollers send the paper on the transport belt to the fuser while transferring the toner images on the drums of each color.
  • Page 24 (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 (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. 2.
