  • Page 24: Drum Charge

    2.8.1 Drum Charge The Drum is charged with static electricity before LED exposure. The Rotating Charge Brush is used for the charging method. The rotating brush charging generate little ozone in the printer. Because the charge is directly given to the Drum, the Drum can be charged by low voltage.

  • Page 25: Image Transfer

    2.8.4 Image Transfer Image transfer is the process of transferring the toner image created on the Drum in the developing process to paper. We use the Roller Image Transfer instead of the Corona Image Transfer, as the image transfer method. In the Roller Image Transfer, there is little generation of ozone due to corona discharge. Also, there is no blur of toner because the paper is always pressed by the Drum and the Image Transfer Roller.

  • Page 26: Fusing

    2.8.6 Fusing An Overview The toner image transferred on to the paper is securely fixed. A heat roller system is used as the fusing system. The toner image is fused by Heater Roller heated by the Heater Lamp, and securely fixed by the pressure between the Heater roller and Press rollers. A Thermistor detects and controls the Heater Roller temperature.
  • Page 27 Fusing temperature 1) Warming Up After the initialization of the printer, warming up of the printer starts and the Heater Lamp turns ON until the temperature of the Heater Roller reaches approx. 185 °C. 2) Printing When the printer obtains the printing command from its controller, the Heater Roller is maintained at 185 °C.
