Detaching And Refitting The Fuser Thermostat - Kyocera TASKalfa 220 Service Manual

(7) Detaching and refitting the fuser thermostat

Follow the procedure below to replace the fuser thermostat.
Cautions
Be sure to replace it after finding the cause of failure.
If the cause is not found, do not replace only the component in question but the entire unit.
If C6000 or C6020 occurs, replace the thermostat after resolving the problem.
Before replacement, conduct continuity check for the thermostat.
Procedure
1. Remove the fuser unit (see page 1-5-40).
2. Remove two positive terminals from fuser
thermostat.
3. Remove two screws and remove the fuser
thermostat.
4. Replace the fuser thermostat and refit all the
removed parts.
Cautions
Insert the terminal all the way into the unit.
Put the slack of electric wire toward the front
side of the machine.
Push each terminal and heater wire into the
housing so as not to exceed the height of
the rib of the fuser unit (because they may
come in contact with the machine frame at
the time of installation of the machine).
5. Use a thickness gauge to check that the
clearance between the fuser thermostat and
the heat roller is within the reference value.
Reference value: 0.7 to 1.5 mm
