After the termination of transfer the unsettled toner image is settled to paper by heat and pressure
while passing between Heat roller and Back up roller. Heat roller is Teflon coated and is mounted by
heater that can generate heat (Halogen lamp).
The thermistor that contacts the Heat roller adjusts the Heat roller temperature to the temperature
specified by the menu complying with the paper width. For safety the thermostat shuts off the voltage
supply to the Heater by opening the thermostat in the case of abnormally temperature increasing.
The back up roller is held by the pressure springs on each terminal due to the pressure applied.
