  • Page 157: Paper Feed/ Conveying Section

    2M4/2M5/2M6/2M7-1 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 158: Manual Feed Section (25/26 Ppm Model Only)

    2M4/2M5/2M6/2M7 (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 160: Drum Section

    2M4/2M5/2M6/2M7 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 161: Developer Section

    2M4/2M5/2M6/2M7 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 162: Optical Section

    2M4/2M5/2M6/2M7-1 2-1-4 Optical section The optical section consists of the image scanner section for scanning and the laser scanner section for print- ing. (1) Scanner unit The image in an original document is scanned using a CIS image sensor. When the document processor (DP) is used for scanning, the CIS unit is parked at the DP reading position and in synchro with the timing of feeding the original document, the DP continuously performs scanning over the subscan direction of the document.

  • Page 163: Laser Scanner Section

    2M4/2M5/2M6/2M7 (2) 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.

    2M4/2M5/2M6/2M7 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 2-1-13 Transfer roller section 1.

  • Page 167: Fuser Section

    2M4/2M5/2M6/2M7 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.
