    3.2.1 Document scanner unit The document scanner unit is equipment which scans the paper using the scanner module. This machine prints the scanning data (copy) or sends data as FAX (FAX transmission). There are two kinds of scanning method of the document scanner unit. One is operation to scan with the document scanner unit, the paper is placed on the document glass, the scanner module moves under the document glass, and it scans the paper, and the other one is operation to scan in cooperation with the ADF unit, scan the paper which has been sent...
  • Page 47 6. Scanning operation (The scanner module moves under the immovable document.) Open the document cover, place a sheet of the document (or opened book) onto the document glass, and close the document cover. Then, the machine starts scanning by the operation of the panel, and the scanner drive mechanism is started and the scanning operation is started.

  • Page 48: Adf Unit

    3.2.2 ADF unit The ADF unit is equipment which sends one document or the document for every plurality to the ADF scanning part of the document scanner unit, and performs continuation scanning. As for the ADF of this machine, the duplex scanning is also possible. Performance of the ADF - The number of maximum capacity: Up to 50 sheets.
  • Page 49 3. Function of each motor/solenoid - ADF motor Driving source of overall ADF. - Paper feed solenoid The paper feed solenoid disable pick-up roller and separation roller while the machine is taking action scanning to prevent the next document from being drawn into the ADF. - Switch back solenoid Switches the direction of rotation of the switch back roller ASSY.
  • Page 50 5. ADF simplex scanning (The document moves over the immovable scanner module.) (1) Set the document face up into the paper feed chute ASSY. 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 rubber send a sheet of the document to the ADF one by one from the top page of the stacked documents.
  • Page 51 6. ADF duplex scanning (The document moves over the immovable scanner module.) (1) Set the document face up into the document chute. When the machine starts duplex 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.

    3.3.3 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 regist solenoid is turned on, the regist roller starts turning, and the paper is fed to the transfer roller in the drum/toner ASSY.

    3.3.4 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 58: Duplex Printing

    3.3.5 Duplex printing After the paper exits from the eject roller ASSY 2 with the front of sheet printed, the eject roller ASSY 2 rotates conversely and feeds the paper to the Duplex unit, where the paper skew is adjusted. Afterwards, the paper is ejected from the Duplex unit to the path through the regist roller and to the transfer block in the drum unit again for process of printing on the back of sheet.

    3.3.6 Paper feeding from the MP tray The separation roller MP 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 paper is drawn out of the MP tray by rotation of the paper feed roller MP contacted with the paper.

  • Page 60: Toner Cartridge

    Toner Cartridge 3.4.1 Methods for Detecting Toner Life When the machine detects the toner life end, "Replace Toner" is displayed. The toner life is displayed through the following two ways. First, such indication is displayed when detection is performed by the toner sensor; second, it is displayed at the time when a cumulative rotation of the develop roller reaches its upper limit.

  • Page 61: Cartridge Life

    3.4.2 Cartridge life A new toner cartridge can print approximately 8,000 A4 or Letter size single-sided pages at normal duty (ISO/IEC19752). In the case of low-duty printing, if the number of printed pages are reached the cartridge life, "Replace Toner" message appears on the LCD before the toner runs out because the developer roller surface or other toner sealing is worn out due to a rotation of the rollers.

  • Page 62: New Toner Detection

    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 63 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 64 <When a toner cartridge in use is inserted after "Replace Toner" is displayed by toner sensor detection > A count value before changes is continuously indicated as a number of the rotation for the develop roller. Irrespective of the amount of toner, printing becomes disabled when the number of the rotation for the develop roller reaches the upper limit.

  • Page 65: 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 66: 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 67 (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 68 (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 69 (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. 2-27 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 70 (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. The thermistor detects surface temperature of the heat roller and turns ON/OFF the halogen heater lamp. The temperature is kept constant. Fuser unit Heat roller Halogen heater...
