  • Page 261 (2) Laser scanner section The image data scanned by the CCD PWB (CCDPWB) is processed on the main PWB (MPWB) and transmitted as image printing data to the laser scanner unit (LSU). By repeatedly turning the laser on and off, the laser scanner unit forms a latent image on the drum surface.

  • Page 266: Transfer And Separation Sections

    2-1-5 Transfer and separation sections The transfer and separation section consists mainly of the transfer roller, separation electrode and drum separation claws. A high voltage generated by the high voltage PWB (HVPWB) is applied to the transfer roller for transfer charging. Paper after transfer is separated from the drum by applying separation charging that is output from the high voltage PWB (HVPWB) to the separation electrode.

  • Page 267: Cleaning And Charge Erasing Sections

    2-1-6 Cleaning and charge erasing sections The cleaning section consists of the cleaning blade that removes residual toner from the drum surface after the transfer process, and the cleaning spiral that carries the residual toner back to the waste toner box. The cleaning lamp (CL) consists of LEDs and removes residual charge on the drum before main charging.
  • Page 268 2-1-7 Fuser section The fuser section consists of the parts shown in Figure 2-1-18. When paper reaches the fuser section after the transfer process, it passes between the press roller and heat roller, which is heated by fuser heaters 1 or 2 (FH1 or FH2). Pressure is applied by the fuser unit pressure springs so that the toner on the paper is melted, fused and fixed onto the paper.

  • Page 270: Eject And Switchback Sections

    2-1-8 Eject and switchback sections The eject and switchback sections eject paper on which fixing has ended with the eject roller that is rotated by forward rotation of the eject motor. In duplex copying, paper is turned over by reverse rotation of the eject motor. When paper is transferred to the job separa- tor or the internal finisher, the feedshift solenoid (FSSOL) is turned on to activate the feedshift guide to switch the paper transfer path.

  • Page 271: Duplex Section

    2-1-9 Duplex section The duplex section consists of the components shown in figure. In duplex mode, after copying on to the reverse face of the paper, the paper is reversed in the switchback section and conveyed to the duplex section. The paper is then conveyed to the paper feed section by the upper and lower duplex feed rollers.
