    3.2.1 Document scanner unit The document scanner unit is equipment which scans the paper using the CIS unit. This machine prints the scanning data (copy) or data is sent by 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 CIS unit moves is the bottom of it, and it scans the paper, and other is operation to scan in connection with the ADF unit, scan the paper which has been sent over the immovable CIS unit.
  • Page 62 (5) Scanning operation (The CIS unit 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 CIS drive mechanism is started and the scanning operation is started.

  • Page 66: Plate-up Function Of The Paper Tray

    3.3.1 Plate-up function of the paper tray The plate of the paper tray is pushed up by the force exerted by the motor not by springs so as to keep the pressure on the paper pick-up roller at a certain level and enhance the paper-feeding performance irrespective of the quantity of remaining papers in the tray.
  • Page 67: Paper Supply

    3.3.2 Paper supply When the paper pick-up solenoid is turned ON, the power of the paper feed motor rotates the paper pick-up roller, and it picks up a few sheets or one sheet of paper from the top of the sheets in the paper tray every time it is rotated and feeds it to the separation roller.
  • Page 68: Paper Registration

    3.3.3 Paper registration Passing of each sheet of paper which is separated by the separation roller is detected by the registration front actuator. Then, the paper is fed further for a certain time, and its front edge hits the stopped PF registration roller so that the paper skew is corrected. After such correction, the registration solenoid is turned OFF, the power of the paper feed motor rotates the PF registration roller, and the paper is fed to the belt unit.

    Toner Cartridge 3.4.1 Type of toner cartridge This product has four types of toner cartridges, K (black), Y (yellow), M (magenta), and C (cyan), and each toner cartridge has starter toner cartridge and standard toner cartridge. The toner cartridges supplied with the product are starter toner cartridges, and the toner cartridges which are sold as consumable parts are standard toner cartridges.
  • Page 72: Method Of Detecting Toner Life

    3.4.3 Method of detecting toner life This product detects the life of the toner cartridges using the following two means. ■ Detection by the toner sensor This product has a function to detect the remaining toner by checking the level at which toner in a cartridge interrupts light using a transmissive light sensor.
  • Page 73 <Life of toner cartridge> The life of the toner cartridge varies according to the average number of print pages per job. (See the table below.) The number of printable pages is larger when making continuous prints in one job because deterioration of the develop roller is low. Relationship between average print page per 1 job and life of toner cartridges Average print page (page/job) Cartridge life (Standard-K)
  • Page 74: New Toner Detection

    3.4.5 New toner detection When a toner cartridge is replaced and a new toner cartridge is mounted, there is a need to reset the develop bias voltage value (refer to next page) to the initial value and to reset prohibition of the print operation by clearing the display of “Toner Low” or “Replace Toner.” The old and new toner cartridges can be identified using the new toner detection mechanism shown below.
  • Page 75 ■ Developing bias voltage Toner in use tends to have a low print density at the beginning of its use, but the density gradually becomes higher after a certain period of use if the bias voltage is kept at a certain level during development.

  • Page 77: Principle Of Color Overlapping

    Principle of Color Overlapping The human eye distinguishes one color from others by receiving light’s three primary colors (Red, Green, Blue). When monochrome lights are received, each color can be sensed. However, when two-color lights, red (R) and green (G), are received, they are recognized as “yellow”;...
  • Page 78: Basic Printing Principle

    Basic Printing Principle The printing process consists broadly of 6 processes: Charging, Exposure, Development, Transfer, Fusing and Cleaning. <Printing process> (1) Charging: The surface of the drum is electrically charged (Primary Charge). (2) Exposure: A printed image is formed on the surface of the drum by applying LED beam (Electrostatic Latent Image).
  • Page 79: Charging

    3.6.1 Charging The exposure drum needs to be evenly electrified to coat toner beautifully on the exposure drum. Ions are produced by supplying high-voltage power to the corona wire. The flow of the ion charge is controlled by the constant voltage of the grid approximately 700 V and electrified the exposure drum surface evenly.
  • Page 80: Exposure

    3.6.2 Exposure Exposure is conducted by LED (Light Emitting Diode) arrays. Four LED arrays for K, Y, M and C are mounted as an LED ASSY on the top cover unit of the main unit. These four LED arrays do not emit different colors corresponding to toner colors, and they are the same parts in terms of structure.
  • Page 81: Development

    3.6.3 Development Toner is attracted to the latent-image area on the exposure drum where surface potential is lowered due to exposure. By controlling the developing bias voltage supplied to the develop roller, the amount of toner taken to the exposure drum is adjusted to keep printing density constant. 400 V (Changes depending on use condition) LED beam...
  • Page 82: Transfer

    3.6.4 Transfer By applying a minus charge to the transfer roller of the belt unit, the toner adhered to the exposure drum is transferred to paper which is traveling on the feed belt. Exposure drum (K) Exposure drum (Y) Exposure drum (M) Exposure drum (C) Belt unit Feed belt...
  • Page 83: Fusing

    3.6.5 Fusing The toner transferred on to the paper passes between the heat roller and the pressure roller in the fuser unit and are fused by heat and pressure. The main CPU detects surface temperature of the heat roller using the thermistor and turns ON/OFF the halogen heater lamp to keep the temperature constant.
  • Page 84: Toner Cleaning

    3.6.6 Toner cleaning <Flow of toner cleaning> (1) Toner remaining on the exposure drum which has not completely been transferred on to the paper is pulled onto the drum cleaner with a lower potential and the drum is cleaned. (2) After the above step, the potential of the drum cleaner is raised during printing, and such attracted toner is returned to the exposure drum again.

    Adjustment of Color Registration In this device, the drum and develop unit are prepared for K, Y, M, and C respectively. Four color images are combined into one image, and therefore color registration error might occur.

    How to Recover from Errors of the Fuser Unit How to recover from errors of the fuser unit is to use Function code 99 in the maintenance mode. WARNING When clearing an error, be sure that the fuser unit is cooled down sufficiently. If an error is cleared while the fuser unit is not cooled down, there is a possibility that the unit might be unable to be repaired.
