9.3.1.3 Controlling the Reciprocating Movement of the Thermistor

iR5065 / iR 5055 / iR5075 / iR5075N / iR5065N / iR5055N
To prevent damage to the fixing roller by the main thermistor (THM1) or the shutter thermistor (THM3), the thermistor is moved in the axial direction of the fixing
roller over a distance of about 12 mm.
The thermistor is moved by the drive from the web drive solenoid (SL9), transmitted to the reciprocating cam by way of a one-way arm.
The following shows the components associated with the mechanism used to control the thermistor reciprocating mechanism:
(REAR)
[1] Fixing roller
SL9: web drive solenoid
THM1: main thermistor
THM3: shutter thermistor

9.3.1.4 Controlling the Reciprocating Mechanism of the Upper Separation Claw

iR5065 / iR 5055 / iR5075 / iR5075N / iR5065N / iR5055N
To prevent damage to the fixing roller by the upper separation claw, the upper separation claw is moved back and forth over a distance of 3 mm in the axial direction
of the fixing roller.
The following shows the construction of the components used to control the upper separation claw reciprocating mechanism.
