    3.4.3 New toner detection This machine is equipped with the function to detect that the residual quantities of the toner are not enough by examining the degree that the toner in the cartridge blocks the light by the transmission light sensor. This function informs the user's that the toner cartridge has reached its life.
  • Page 79 When the new toner detection machanism detects that the toner cartridge is replaced with a new one, the developing bias voltage is initialized at the same time. The toner used for the machine has a property that print density is light first and gradually darker in the course of usage.

  • Page 81: Print

    Print 3.5.1 Basic Principle The printing process consists broadly of 5 processes: electrification, exposure, development, transfer and fusing. 1. Charging: The surface of an exposure drum is electrically charged. 2. Exposure: A printed image is formed on the surface of the drum by applying laser beam. 3.

  • Page 82: Print Process

    3.5.2 Print Process (1) Charging The flow of the ion charge is controlled by constant voltage of the grid 850 V to ensure it is distributed evenly on the drum surface. In order to coat toner on the exposure drum, the drum needs to be evenly electrified.
  • Page 83 (2) Exposure The laser beam radiated from a laser diode inside the laser unit is concentrated into a constant width by a slit in the CO lens cell and then reflected by a polygon mirror rotating at high speed. The evenly charged exposure drum is irradiated with reflected light and exposed. Surface potential is lowered by such exposure and a printed image is formed.
  • Page 84 (3) Development Toner is attracted to a printed-image area on the exposure drum where surface potential is lowered due to exposure. By controlling developing bias voltage supplied to the develop roller, the amount of toner taken to the drum is adjusted to keep printing density constant. Charging Laser beam 400 V to approx.
  • Page 85 (4) Transfer By applying a minus charge to the transfer roller, the toner adhered to the exposure drum is transferred to paper. Supply roller Toner cartridge Develop roller Exposure drum Toner Transfer roller Fig. 2-33 Memo : • Control of transfer bias The transfer bias applied in the transfer roller is adjusted according to types and sizes of paper so as to keep excellent image quality.
  • Page 86 (5) Fusing The toner transferred on paper passes between the heat roller and the pressure roller in the fuser unit, being fused by heat and pressure.
