2.4.6.3  Fusing Temperature Control

FUSING TEMPERATURE CONTROL CIRCUIT

The resistance of the thermistor (TH) mounted on the fusing roller varies with temperature, 
particularly, lowers as temperature rises. The output from the thermistor (TH) is input to the 
analog port of the CPU of the control circuit.

As temperature rises and the resistance of the thermistor (TH) lowers, the voltage input to 
the analog port lowers.

The CPU monitors the output from the thermistor and turns on and off power to the heater 
to control the temperature of the Fusing Roller.

To turn on the fusing roller heater lamp (H1), the CPU turns the heater remote output signal 
“ON (L)”. By turning the heater remote output signal “ON (L)”, the triac of the DC 
regulated power supply is turned on and the AC voltage is applied to the fusing heater 
lamp(H1) to heat the heater.

If the temperature of the Fusing Roller is too high, the too-high temperature detection 
circuit operates to stop forcibly the current to the fusing heater lamp (H1).

FUSING TEMPERATURE CONTROL

The fusing roller heater lamp (H1) inside the Fusing Roller and the pressure roller heater 
lamp (H2) execute temperature control as described below.

The surface temperature of the Fusing Roller is converted to an electric signal by the 
thermistor (TH1) for detection.

WARM-UP CONTROL

The preset temperature for warming up is 170

°

C.

Once the temperature of the Fusing Roller has reached the preset level, the fusing roller 
heater lamp and pressure roller heater lamp are turned off.

STANDBY TEMPERATURE ADJUSTMENT CONTROL

The preset temperature for standby is 171

°

C.

PRINTING TEMPERATURE ADJUSTMENT CONTROL (DURING 

MONOCHROME PRINTING)
