  • Page 195 KX-FL612CX / KX-FL612CX-S The following is an overview of how the power supply unit is controlled. The control method of this power supply unit is pulse width modulation. When Q is ON, the energy is charged in the transfer primary coil according to E .
  • Page 196 KX-FL612CX / KX-FL612CX-S [Surge Absorber Circuit] This circuit is for absorbing surge voltage generated by the transformer. [Control Circuit and Detecting Circuit] The control circuit amplifies the output with increased voltage detected in the error detecting circuit. Then it drives the main transistor.

    KX-FL612CX / KX-FL612CX-S 8 REFERENCE MATERIALS DATA 8.1. PRINTING OPERATION PRINCIPLE 8.1.1. PROCESS CHART AND PROCESS BIAS 8.1.2. CHARGING Charging is the stage that keeps the surface of the sensitive drum a fixed electric potential. The sensitive drum is the Organic Photo Conductor (OPC), which is a electric conductive cylinder whose surface is covered with the Charge Generation Layer (CGL) and Charge Transfer Layer (CTL).
  • Page 198 KX-FL612CX / KX-FL612CX-S 8.1.3. EXPOSING When the drum which is charged with the fixed electric charge is irradiated by the laser beam, the plus charge and minus charge are generated at the Charge Generation Layer. Passing through the Charge Transfer Layer which conducts the plus charge, the minus-charged drum´s surface is neutralized to be skipped.
  • Page 199 KX-FL612CX / KX-FL612CX-S 8.1.5. DEVELOPING AND TRANSCRIPTION The developing is the stage that the OPC drum with an invisible image is changed to visible by the toner. The developer consists of mixing paddle, toner supply roller, developing roller, developing blade and OPC drum. The bias voltage is added to the developing roller (DC -200V) and toner supply roller (DC -200V).
  • Page 200 KX-FL612CX / KX-FL612CX-S 8.1.6. CLEANING The toner attached to the surface of the OPC drum is transferred to the paper at the transcription stage, but a part of the toner remains. The cleaning is the stage that cleans the remain toner after the transcription stage. The remain toner on the drum and the toner which was attached to the place where the laser beam didn´t scan are gathered to the developing roller to be used again.
  • Page 201 KX-FL612CX / KX-FL612CX-S 8.1.7. FIXING On the process of the transfer, the transferred toner is weakly attached on the paper. Fixing means the process to fix the toner on the paper permanently. The fixing part melts the toner at the high temperature using the halogen heater. The toner is fixed on the paper by the heat and pressure through the fixing part with the image.
