  • Page 92: Drum Section

    2-1-2 Drum section (1) Drum section The durable layer of organic photoconductor (OPC) is coated over the aluminum cylinder base. The OPC tend to reduce its own electrical conductance when exposed to light. After a cyclic process of charging, exposure, and development, the electrostatic image is constituted over the OPC layer.

  • Page 93: Main Charger Unit

    (2) Main charger unit As the drum rotates in a “clean (neutral)” state, its photoconductive layer is given a uniform, positive (+) corona charge dis- persed by the main charger wire. Due to high-voltage scorotron charging, the charging wire can get contaminated by oxi- dization after a long run.

  • Page 94: Expose Section

    2-1-3 Expose section (1) Laser scanner unit The charged surface of the drum is then scanned by the laser beam from the laser scanner unit. The laser beam (780 nm wavelength) beam is dispersed as the polygon motor revolves to reflect the laser beam over the drum.

  • Page 96: Developing Section

    2-1-4 Developing section The latent image constituted on the drum is developed into a visible image. The developing roller contains a 3-pole (S-NS) magnet roller and an aluminum cylinder rotating around the magnet roller. Toner attracts to the magnet sleeve since it is powdery ink made of black resin bound to iron particles.

  • Page 97: Transfer/Separation Section

    2-1-5 Transfer/separation section The transfer/separation section consists of the transfer roller, discharger brush and paper chute guide. A high voltage gen- erated by the high voltage PWB is applied to the transfer roller for transfer charging. Paper after transfer is separated from the drum.

  • Page 98: Cleaning Section

    2-1-6 Cleaning section After the transferring process, the drum needs to be physically cleaned of toner which is residual after the development process. The cleaning blade is constantly pressed against the drum and scrapes the residual toner off to the sweep roller. The waste toner is collected at the output end of the sweep roller and sent back to the toner container, into the waste toner reservoir.

  • Page 99: Fuser Section

    2-1-7 Fuser section The toner on the paper is molten and pressed into the paper as it passes between the heat roller and the press roller in the fuser unit. The heat roller has a heater lamp inside which continuously turns on and off by the fuser thermistor to maintain the constant temperature onto the heat roller surface.
