Service Bulletin COPIER
Issued by Canon Europa N.V.
Model : GP605 No.: GP605-007
(FF-T01-K1-000016-01)
DATE: 07.05.99
Location : FIXING ASSEMBLY
Subject : DISPLACEMENT OF SCREW SECURING RECIPROCATING SHAFT BUSHING
Reason : This bulletin communicates measures to take in the filed to prevent quality problems caused by
displacement of the screw used to secure the reciprocating shaft bushing.
Details : It was found, different models, that the screw used to fix the reciprocating shaft bushing in place
becomes loose because of heat or vibration, ultimately falling off the bushing.
In the worst case, the screw falling between the thermal switch and the reciprocating shaft can short-
circuit the power line of the fixing heater.
This bulletin contains measures for preventing such a problem as a precaution for the GP605, which is
deigned based on the same concept.
< Factory measure >
Tentative Measures: The screw used to secure the reciprocating shaft bushing is replaced with a
W-sems screw, which tends to remain firmly tightened.
XB1-2400-609 (binding screw) ->XB2-8400-809 (W-sems screw)
Permanent Measures: The screw (6mm-long) used to secure the reciprocating shaft bushing is
replaced with an 8mm-long screw. Further, tightening of the nut is added to
the work.
Servicing : As part of a servicing visit, replace the 6mm-long screw used to secure the reciprocating shaft bushing
with an 8mm-long screw. In addition, tighten the nut.
< Points to Note during Work >
Check to make sure that the fixing assembly is not hot before starting the work.
Take care not to damage the fixing roller and the cleaning belt.
Check the existing reciprocating shaft bushing, and replace it if a crack is found.

For instructions between sliding out the
fixing/feeding assembly and detaching the
fixing cleaning belt, see the Service Manual
(FY8-13FD-000; pp. 8-26, -27, -29, -30).
However, you need not detach the fixing
assembly from the fixing/feeding assembly.

6) Replace the screw used to secure the reciprocating shaft bushing, and tighten the nut. (Figure 6)
Replace the screw used to secure the reciprocating shaft bushing with an 8mm-long screw
(XB1-2400-807), and tighten it lightly so that there is no play in the bushing.
With a screwdriver fitted to the screw, attach the nut (XB7-2100-409) to the screw; then,
tighten it. At this time, keep the screw still using the screwdriver.
