    2-1 Mechanical construction 2-1-1 Paper feeding/conveying section The paper feeding/conveying system picks up paper from the paper cassette, manual feed tray, feeds it in the printer and delivers in the output tray. Paper is feed at the precise timing in synchronization with data processing. (1) Paper feed section The figure below shows the components in the paper feeding/conveying section and the paths through which the paper travels.

  • Page 99: Drum Section

    2-1-2 Drum section (1) Drum unit 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 100: 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 101: 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 (27959 rpm) to reflect the laser beam over the drum.
  • Page 102 Figure 2-1-7Laser scanner unit Laser diode ..........Emits diffused, visible laser. Cylindrical lens..........Compensates the vertical angle at which the laser beam hits a polygon mirror segment. Polygon mirror (motor) ........ Has six mirror segments around its hexagonal circumference; each mir- ror corresponding to one scanned line width on the drum when laser beam scans on it.

  • Page 103: Developing Section

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

  • Page 105: Transfer Section

    2-1-5 Transfer section The image developed by toner on the drum is transferred onto the paper because of the electrical attraction between the toner itself and the transfer roller. The transfer roller is negatively biased so that the positively charged toner is attracted onto the paper while it is pinched by the drum and the transfer roller.

  • Page 106: 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 107: Fuser Section

    2-1-7 Fuser section (1) Fuser unit 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 (750 W) inside which continuously turns on and off by the fuser thermistor to maintain the constant temperature onto the heat roller surface.

    2-1-8 Paper exit section (1) Paper exit section The paper exit section transports the paper which passed the fuser unit towards the output tray. The paper which passed through the fuser unit turns on the exit sensor which is driven by the fuser actuator in the fuser unit, and is led by the guide comprised of the rear cover and the frame, finally reaching the FD roller.
