    2M2/2M3 2-1 Mechanical Construction 2-1-1 Paper feed/conveying section Paper feed/conveying section consists of the paper feed unit that feeds paper from the cassette and the MF tray (Manual feed tray) paper feed unit that feeds paper from the MF tray(25/26 ppm model), and the paper conveying section that conveys the fed paper to the transfer/separation section.

  • Page 88: Manual Feed Section(25/26 Ppm Model Only)

    2M2/2M3 (2) Manual feed section(25/26 ppm model only) Manual feed section consists of the MF sheet, MF base and the paper feed pulley (same as the cassette) for extracting and conveying the paper. Paper is fed out of the MF tray by the rotation of the paper feed pulley.Paper is automatically fed from the manual feed tray if paper is present in the tray.

  • Page 90: Drum Section

    2M2/2M3 2-1-2 Drum section The drum section consists of the charger roller, drum and cleaning section. The drum is electrically charged uniformly by means of a charger roller to form a latent image on the surface. The cleaning section consists of the cleaning blade and the drum screw which remove residual toner from the drum surface after transfer.

  • Page 91: Developer Section

    2M2/2M3 2-1-3 Developer section The developer unit consists of the sleeve roller that forms the magnetic brush, the magnet roller, the devel- oper blade and the developer screws that agitate the toner. Also, the toner sensor (TS) checks whether or not toner remains in the toner container.

  • Page 92: Optical Section

    2M2/2M3 2-1-4 Optical section The optical section consists of the laser scanner section for printing. (1) Laser scanner section The charged surface of the drum is then scanned by the laser beam from the laser scanner unit. The laser beam is dispersed as the polygon motor (PM) revolves to reflect the laser beam over the drum. Various lenses are housed in the laser scanner unit, adjust the diameter of the laser beam, and focalize it at the drum sur- face.

  • Page 95: Transfer/Separation Section

    2M2/2M3 2-1-5 Transfer/Separation section The transfer/separation section consists of the transfer roller, discharger brush. 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. Figure 2-1-11 Secondary transfer roller section 1.

  • Page 96: Fuser Section

    2M2/2M3 2-1-6 Fuser section The paper sent from the transfer/separation section is interleaved between the heat roller and the press roller. The heat roller is heated by the fuser heater (FH), and the toner is fused by heat and pressure and fixed onto the paper because the press roller is pressed by the fuser press spring.
