The toner image transferred on the paper is impressed with heat and pressure and is fused
to the paper when the paper passes through the heat roller and the back-up roller.
Further, a thermostat is equipped for the safety’s sake and if the temperature of the heat
roller rises above a certain degree, the thermostat opens and shuts the power supply to the
heater.
