II. CONTROLLING THE FIXING TEMPERATURE
A. Controlling the Area of Heating (fixing roller)
The upper fixing roller is heated by two heaters: main heater (H1) and sub heater
(H2).
The copier’s main and sub heaters are halogen lamps with different thermal
distribution characteristics. (Figure 6-201)
The surface temperature of the fixing roller is maintained even by varying the period
in which these two heaters are turned ON while at the same time preventing overheating
of the ends.
