  • Page 41: Plate-Up Function Of The Paper Tray

    3.2.1 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 pressure to the paper pick-up roller and enhance paper-feeding performance irrespective of the quantity of papers remaining in the tray.

  • Page 42: Paper Supply

    3.2.2 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 43: Paper Registration

    3.2.3 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.

    3.2.4 Paper eject Drive of the fuser/eject drive motor rotates the heat roller and pressure roller of the fuser unit, and toner on paper is fused as the paper is being fed.

    3.2.5 Paper supply from manual feed slot and paper eject from back When making print from the manual feed slot, set papers on it with the print side up. A sheet of paper which is inserted from the manual feed slot one by one presses the manual paper actuator, and consequently the actuator detects that there is a sheet of paper.

  • Page 46: Toner Cartridge

    Toner Cartridge 3.3.1 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 47: Method Of Detecting Toner Life

    3.3.3 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 48 <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 49: New Toner Detection

    3.3.5 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 50 ■ 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 51: Method Of Counting The Number Of Toner Replacements

    3.3.6 Method of counting the number of toner replacements This machine keeps the number of times that the toner cartridges are replaced and the page counters to learn the usage of the machine. These counters will not be deleted even if the power is turned OFF.

  • Page 52: 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 53: 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 54: Charging

    3.5.1 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 55: Exposure

    3.5.2 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 56: Development

    3.5.3 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 57: Transfer

    3.5.4 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...

    3.5.5 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.

    3.5.6 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. Auto color registration error correction control is to calculate the color registration error amount and adjust the exposure timing as a means to prevent color registration error.
