stage
The image transferred to the paper by static electricity is fixed by heat and pressure when
passing through the heat roller and the pressure roller in the fixing unit. The thermistor keeps
the surface temperature of the heat roller constant by detecting the surface temperature of the
heat roller and turning on or off the halogen heater lamp.
