    Chapter 12 Printer Operation Guide 12.5 Electrophotographic Process Operation 12.5.1 Primary Charger Primary charger process is the first step in the creation of the electrostatic latent image, which maintains an even charge across the surface of the photoconductor drum. The Printer uses the reliable corona charger (a scorotron type with superb negative chargeability).

    Chapter 12 Printer Operation Guide 12.5.3 Exposure The Printer uses a LED head for its digital exposure process. LED head functions (a) Exposure function Emit light to create the latent image for the photoconductor. (b) Head/internal temperature measurement function A thermistor is installed inside the head unit to measure the internal temperature as well as the head temperature.

  • Page 703: Developer

    12.5.4 Developer This is the process of adding toner on top of the electrostatic latent image, on the surface of the photoconductor drum, to create a visible image. When pre-charged toner is put in contact with the photoconductor, the toner either sticks or does not depending on the charged state of the photoconductor surface.

  • Page 704: Transfer Unit

    Chapter 12 Printer Operation Guide 12.5.5 Transfer Unit The transfer process develops the electrostatic latent image, then takes the toner that is stuck to the photoconductor by the Coulomb force, and works against the Coulomb force to move that toner to the paper or other base material (otherwise known as the electrostatic transfer process).

  • Page 705: Separator

    12.5.6 Separator After the transfer process, the diffuse process consists of using both a standard discharge separation and a separating claw. Separator unit functions (a) Paper discharge function This discharges electricity so that no reverse polarity electrical charge is left on the paper separator and photoconductor drum.

  • Page 706: Discharge Unit

    Chapter 12 Printer Operation Guide 12.5.8 Discharge Unit After the transfer process, the residual potential on the photoconductor surface is at an uneven value due to the different functions of each process invoked. If left in this state, past latent images could appear on the image in subsequent processes.
  • Page 707 Outline of the heat roller fusing method (a) Basis Toner fusing is a 5-step process: Toner particles are heated to sinter. (ii) Fused. (iii) Deformed (expanded) and the paper is moistened. (iv) The melted toner anchors between the fibers of the paper. After the particles are cooled, they harden and fuse to the paper.

There is also a motor for the developer and cutter drive system which can operate independently.
  • Page 709 Cutter Paper is cut using a slitter method. When a cut is performed a buffer is placed on the paper beforehand in order to prevent image quality reduction due to changes in paper behavior. The time required for cutting the paper is approximately 0.6 seconds, with a paper buffer of approximately 80 mm.
