When the machine starts simplex scanning, the ADF motor is rotated clockwise, the pick-up roller draws the document, and the separation roller and separation pad send a sheet of the document to the ADF one by one from the top page of the stacked documents.

  • Page 75 The plate ASSY in the paper tray is pushed up with the motor drive and not with the spring in order to maintain the constant paper feeding performance regardless the number of sheet remained in the tray. When the paper tray (Tray1 cassette) is installed into the machine, the lift gear 46 is rotated, and the motor drive is transmitted to the plate ASSY so that it is pushed up.
  • Page 76: Paper Registration

    3.2.3.2 Paper registration After the paper top position is detected by the regist actuator front, the paper, separated into individual sheets by the separation roller, is fed further for a specified time, and the paper top position reaches the regist roller so that the paper skew is adjusted. Then, the register solenoid is turned off, the paper feed roller starts turning, and the paper is fed to the transfer roller in the drum/toner ASSY.
  • Page 77: Developing

    3.2.3.4 Developing Developing causes the toner to be attracted to the electrostatic image on the drum so as to transform it into a visible image. The developer consists of a non-magnetic toner. The developer roller is made of conductive rubber and the supply roller (which is also made of conductive sponge) rotate against each other. The toner is charged and carried from the supply roller to the developer roller.
  • Page 78: Fixing Stage

    3.2.3.5 Fixing stage The image transferred to the paper by static electricity is fixed by heat and pressure when passing through the heat roller and the pressure roller in the fuser unit. The thermistor keeps the surface temperature of the heat roller constant by detecting the surface temperature of the heat roller and turning on or off the halogen heater lamp.
  • Page 79: Paper Eject

    3.2.3.6 Paper eject After the printing image on the exposure drum is transferred onto the paper, the paper is fed to the fuser unit to fix unfixed toner onto the paper by the heat roller and the pressure roller in the fuser unit.
  • Page 80: Duplex Printing (For The Models With The Dx Only)

    3.2.3.7 Duplex printing (For the models with the DX only) After the paper exits from the eject roller ASSY with the front of sheet printed, the eject roller ASSY rotates conversely and feeds the paper to the duplex tray, where the paper skew is adjusted. Afterwards, the paper is ejected from the duplex tray to the path through the regist roller and the transfer roller to the transfer block in the drum unit again for process of printing on the back of sheet.
  • Page 81: Paper Feeding From The Mp Tray

    3.2.3.8 Paper feeding from the MP tray The separation roller is connected with the feed roller through the gear in the MP roller holder ASSY. When the separation roller is driven, therefore, the feed roller is also driven. At this time, the recording paper is drawn out of the MP tray by rotation of the feed roller contacted with the recording paper.
