(6) Fusing
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.
