    2.2.3 Heat-fixing mechanism As the paper passes between the heater roller and the pressure roller in the heat-fixing unit, the heater roller fuses the toner on the paper. The controller monitors the internal resistance of the heater thermistor to keep the surface temperature of the heater roller
  • Brother International 9870 | Service Manual - Page 40
    2.2.4 Paper ejecting mechanism After the paper passes through the heat-fixing process, it will be ejected from the heat-fixing unit by the paper ejection roller. If the leading edge of the paper pushes up the actuator of the paper ejection sensor, the sensor signals the start of paper ejection. If
