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. -1/4- GP605-007 < Work Procedure > Fixing cleaning belt 1) Remove the fixing cleaning belt.
