3. OPERATION AND TIMING
6. Reciprocating Mechanism of the Thermistor
To prevent damage to the upper fixing roller by the thermistor (THM1), the thermistor is moved back and
forth along the axis of the upper fixing roller over a distance of 12 mm.
The thermistor is moved back and forth by transmitting the drive from the upper fixing web take-up
solenoid (SL3) through a one-way arm to the reciprocating cam.
