    Chapter 6 Principle s of O peration 1.3 Technical explanation of printing processes 1.3.1 Charge In "Charge" process, the surface of drum that rotates at regulated speed is negatively charged evenly by discharging of BCR (Bias Charge Roll). BCR contacts the drum at all times, and follows the rotation of the drum. BCR is a conductive roll, to which negative voltage of overlapped AC voltage is applied from HVPS and it discharges to the surface of the drum.

  • Page 541: Exposure

    Chapter 6 Principle s of O peration 1.3.2 Exposure In the "Exposure" process, the negatively charged drum surface is scanned by a laser beam and an invisible electrostatic latent image is formed on the drum surface. The laser beam is radiated from a laser diode inside the ROS ASSY and scans the drum surface from end to end in the shaft direction via a polygon mirror, fixed mirror and the Scanner Assy lens inside ROS ASSY.
  • Page 542 Chapter 6 Principle s of O peration The laser beam is radiated according to the printing data (image data) output from the printer controller. The laser beam is output only when printing data is pixels (micro points composing characters or pictures). (The laser diode lights up for parts to be developed by toner, and not for parts that are not to be developed.) The drum surface radiated by the laser beam becomes a conductor, and the negative charge on the drum surface flows to the positive side and the charges negate each other so that the...

  • Page 543: Development

    Chapter 6 Principle s of O peration 1.3.3 Development In the "Development" process, toner is electrically attached to invisible electrostatic latent image on the drum surface to form a visible image on the drum surface. This device uses a "Rotary developing method" that rotates and moves 4 Developer Assy sequentially and a "Trickle developing method"...
  • Page 544 Chapter 6 Principle s of O peration When the number of prints increases, the consumption of toner in the Developer Assy also increases. In order to maintain an appropriate developer concentration, it is necessary to refill with an amount of toner equivalent to that consumed from Toner Cartridge to Developer Assy. This refilling process is called "Toner dispense".

  • Page 545: 1St Transfer (Drum To Belt)

    Chapter 6 Principle s of O peration 1.3.8 Neutralization In the "Neutralization" process, the charge on the paper is neutralized or removed by Detack Saw (neutralizing plate). Detack Saw is a metal sheet that contacts the rear side of the paper, and a negative voltage is applied to it from HVPS.

  • Page 551: Fixing

    Chapter 6 Principle s of O peration 1.3.10 Fixing In the "Fixing" process, toner is fixed on the paper by heat and pressure.
