CHAPTER 2 EXPLANATION OF OPERATION
8. Fuser
The toner image which was transferred to the paper is applied heat and pressure as it passes
between the heat roller and the backup roller, and it is therefore fused onto the paper.
For the sake of safety, a thermostat is provided; it comes on to cut off the voltage supplied
to the heater if the heat roller temperature rises above a certain preset temperature.
