  • Page 62: Operation Overview

    Operation theory Operation overview Electrophotographics system Electrophotography is the technology used in laser printing which transfers data representing texts or graphics objects into a visible image which is developed on the photosensitive drum, finally fusing on paper, using light beam generated by a laser diode. This section provides technical details on the printer’s electrophtography system.

  • Page 63: Photoconductive Drum

    Operation theory Operation overview Photoconductive drum The durable layer of organic photoconductor (OPC) is coated over the aluminum cylinder base. The OPC tends to reduce its own electrical conductance when exposed to light. After a cyclic process of charging, exposure, and development, the electrostatic image is constituted over the OPC layer.

  • Page 64: Charging The Drum

    Operation theory Operation overview Charging the drum Figure below is a simplified diagram for explaining how the drum is electrically charged. The roller charging system that gives electrical charge on the photoconductive drum using an electroconductive rubber roller is used. The rubber roller is pressed against the drum by means of the pressure given by coil springs and rotates following the drum’s revolution.
  • Page 65 Operation theory Operation overview The diagram below is to explain how the DC bias is weighted by AC. Note that the bias is increased to erase the residual latent image while the paper does not exists below the drum unit. Main motor activation Paper (length) 0.9 kV...

  • Page 66: Exposure

    Operation theory Operation overview Exposure The exposure process is done by emitting the laser light onto the photoconductive drum. The laser light (780 nm wavelength) beam is dispersed by scanning use of the polygon motor and polygon mirrors perpendicular to the (portrait) image. Various lenses and mirrors are housed in the scanner unit and used to adjust the diameter of the laser beam and focalize it at the drum surface.

  • Page 68 Operation theory Operation overview SURFACE POTENTIAL The laser beam is continually switched depending on the print data. It is on for a black (exposed) dot and off for a white (blank) dot. Since the drum surface is evenly charged, whenever it is illuminated by the laser beam, the electrical resistance of the photoconductor is reduced, the potential on the photoconductor is also lowered.

  • Page 69: Development

    Operation theory Operation overview Development The development process visualizes the electrostatic image on the drum using toner. The dual component development system is used in the printer that uses a mixture of ferrite carrier and toner as the developer powder. These two developing powder are constantly agitated within the developer unit for uniform mixture by the mixers.

The decrease in the toner-to-carrier mixture ratio at the developer bottom is detected by the toner sensor at its diaphragm.

  • Page 72: Transfer

    Operation theory Operation overview Transfer The transfer process lets the image developed by the toner on the photoconductive drum electrically transferred onto paper. The conductive rubber roller applies the positive bias at the back side of paper, allowing the negatively charged toner transferred onto the paper. The transfer roller must be handled with great care because oily substances such as grease can harm not only the transfer roller but the photoconductive drum and other components in the general proximity.
  • Page 73 Operation theory Operation overview surface. The temperature is approximately 150°C for model FS-600 and 160°C for model FS-680 while the printer is adle; approximately 165°C for model FS-600 and 182°C for model FS-680 while printing. The heat roller is resin coated by florin to prevent toner from accumulating on the roller. Care must be taken while handling the heat roller not to scratch the roller surface as doing so may result in print problems.

  • Page 74: Drum Cleaning

    Operation theory Operation overview Drum cleaning After the transferring process, the excessive toner remaining on the drum surface is scraped off by the cleaning blade. The toner is conveyed through the drum unit conveyer for collection in the waste toner reservoir inside the toner container. The maximum capacity of the waste toner reservoir exceeds the amount of the toner inside the toner container, making the chance of toner overfilling unlikely.

    Operation theory Operation overview Sensors A photo penetration type sensor is used for the paper feed sensor, registration sensor, and the exit sensor (fuser). While paper is not present as shown in !, the reflector at one end of the sensor’s actuator is normally seated inbetween the photo transmitter and the sensor.

  • Page 79: Cassette Feeding

    Operation theory Operation overview Cassette feeding The main logic controller sends the PRINT* signal to the engine controller after it has finished processing data. The engine controller CPU then starts the main motor (MOTDR), polygon motor, registration rollers, and the fuser heater. The engine controller then issues the FEDDR signal which connects the main motor power to the paper feed tire.
