Service Bulletin COPIER
Issued by Canon Europa N.V.
Model : GP605 No.: GP605-005 Rev. 1
(FF-T01-K1-000009-02)
DATE: 04.06.99
Location : SLIDE GUIDE (ON ADF PICKUP TRAY)
Subject : PREVENTING JAMS WHILE READING AN ORIGINAL
Reason : The adhesive used on the leaf spring of the slide guide of the ADF can fail, possibly causing a jam
because of the resulting incorrect detection of the size of an original during reading operation. This
bulletin communicates measures to take as part of servicing work to prevent the problem.
Details :
When copies are made using the ADF, wrong detection of paper size can at times occur during
reading operation, causing jams.
A portion of the leaf spring of the slide guide (rear) found on the ADF pickup tray can fail against the
upward force of the ribs found under the spring, resulting in detachment.
Tentative Measures
The ribs of the slide guide (used to prevent noise; see the figures below) are shaved off to limit the
stress against the glued portion (switch-over on and after March 30, 1999).
Permanent Measures
In addition to the tentative measures above, the shape of the leaf spring will be modified to prevent
stress on the leaf spring (see the figures below; switch-over on and after April 13, 1999).
