(24) Remove the screw and take off the actuator holder. Then unhook end "A" of the ejection

Reassembling Notes
• A new heat-fixing unit will be provided with the heater thermistor harness being taped to the unit.
Before installing the unit, remove the tape.
• If you remove and reinstall the heat-fixing unit because of any failure, make the equipment enter
the maintenance mode (by pressing the
Menu

,

, and
4
keys) after completion of
reassembly and then make it exit from the mode (by pressing the
9
key twice). Otherwise, the
heat-fixing unit may not become energized because of the following reason:
If the failure of the heat-fixing unit is caused by an opening of the thermistor circuit (that senses
the temperature of the heat-fixing unit), the system misinterprets the hot heater as being cold.
As a result, the temperature of the heat-fixing unit may become excessively high. To prevent
the system from heating the hot heater further at the next powering-on, it is designed so that the
heater will not be energized. To cancel this setting, you need to carry out the above
maintenance-mode procedure.
