Points to note when attaching the pressure roller heater in the
secondary fixing assembly
[Description]
When the pressure roller heater is incorrectly set in the secondary fixing assembly, the AC cable of the pressure roller heater
may be damaged and the following symptoms may occur.
- Power shut-off from a leakage breaker on the machine being activated
- Power shut-off from a leakage breaker on the distribution board being activated that is located in the room where the machine
is installed in.
The pressure roller heater is not shown in the figure in "Assembling the Secondary Fixing Roller Heater" of Service Manual, but
the pressure roller should be attached with the pressure roller heater inserted inside. To attach the pressure roller to the secondary
fixing assembly, follow the steps described in "Service Work".
[Remedy/Answer]
This section describes the steps to insert the pressure roller heater into the pressure roller and then attach the pressure roller to
the secondary fixing assembly.
The photo below shows the secondary fixing assembly [1] being pulled out from the machine with the upper and under units being
opened. The photo showing the end of the pressure roller in the rear side of the machine is placed to the left below as [A] and
the photo showing the end of the pressure roller in the front side of the machine is placed to the right below as [B]. Refer to these
photos and compare the rear side [A] and the front side [B] as you perform the work described.
1) Refer to "Assembling the Secondary Fixing Roller Heater" of Service Manual and insert the pressure roller heater into the
pressure roller.
2) Lift the pressure roller. When doing so, press the insulator of the pressure roller heater on the front side [B] so it does not stick
out from the end of the pressure roller. On the rear side [A], the insulator [a] of the pressure roller heater sticks out from the end
of the pressure roller.
