2.8.2 Various Control Mechanisms
2.8.2.1 Fixing Temperature Control
2.8.2.1.1 Heater Temperature Control
0008-0379
The heater temperature control mechanism consists in monitoring the surface temperature of the fixing heater and controlling the fixing heater drive signal
so that the temperature of the fixing heater is identical to the target temperature.
Heater: There is a single heater (fixing heater; H1) used to heat the fixing film (ceramic heater).
Thermistor: There is a single thermistor (main thermistor; TH1) used for the control of the
temperature of the fixing heater (non-contact thermistor).
Thermal fuse: There is a single thermal fuse (thermal fuse; TP1) used to detect overheating of the fixing
heater (non-contact fuse). The thermal fuse is designed to melt in response to overheating
of the hearer, thus cutting off the power to the heater.
