Service Bulletin COPIER
Issued by Canon Europa N.V.
Model : MULTI OUTPUT TRAY-D1 No.: GP405-007
(FF-T01-W-000060-01)
DATE: 09.07.99
Location : INTERIOR OF MACHINE (GP MAIN UNIT), FEED UNIT (MULTI OUTPUT TRAY- D1)
Subject : JAMS WHEN MULTI OUTPUT TRAY-D1 IS CONNECTED TO MAIN GP UNIT AND FACE
DOWN DELIVERY MODE IS SELECTED
Reason : To communicate means to prevent jams in the face down delivery mode when the multi output tray-D1
is connected
Details :
When you select the face down delivery mode with the multi output tray 3-D1 connected to the main
GP unit, the copy paper fed from the GP main unit fixing assembly is reversed by the switching of
paper deflector 2, and is then delivered onto the tray. This reversing of the copy paper will sometimes
cause a jam when the leading edge of the copy paper makes contact with the leading edge of the paper
deflector 2 flapper sheet.
Limp copy paper and copy paper which has been left in a high humidity environment will curl
downward to a greater extent when it is delivered from the fixing assembly. If a feed upper guide plate
with a shallow depression (0.1mm instead of the stipulated 0.4mm) is installed, the position where the
leading edge of the flapper sheet makes contact with the upper feed guide plate will become lowered.
A combination of the upper feed guide plate with the shallow depression and the aforementioned copy
paper with a large downward curl will result in the leading edge of the copy paper to strike the leading
edge of the flapper sheet of paper deflector 2 when the copy paper is reversed for face down delivery,
causing a jam to occur. (Fig. 1-1)

There will be strict supervision over the adherence to 0.4mm deepness for the upper feed guide plate
depression. This is to avoid leading edge of the copy paper with a large downward curl to strike the
leading edge of the flapper sheet when the copy paper is reversed. (Fig. 1-2) Also in order to make
the tolerance less tight for the copy paper with large downward curl, the shape of the stay for the multi
output tray-D1 and the angle in sticking the flapper sheet of the paper deflector have been changed.
With these changes the position where the flapper sheet of the paper deflector plate 2 will make
contact with the upper feed guide plate 2 shifts further upward. This will allow the leading edge of
the paper with a large downward curl to avoid striking the leading edge of the flapper sheet by a more
comfortable margin. (Fig. 2-1, 2-2)

Servicing : When a jam occurs with the aforementioned symptoms, replace the GP main unit's upper feed guide
by following the upper feed guide replacement procedures outlined below. However, the installation
of the upper feed guide with insufficient deepness for the depression may be confined to the machines
bearing the serial number in following ranges.

7) Holding the delivery assembly latch in the left hand
and the lower part of the multi output tray- D1 with
the right hand, remove the multi output tray-D1 from
the main unit (Fig. 8).
Note: When placing the multi output tray-D1 (which
was removed from the main unit) on the floor,
orient the tray to bring the delivery tray to the
bottom.

Service Parts :Because feed guides with deepness of 0.1mm have not been shipped to the field as service parts, it is
possible to receive a feed guide with a deepness of 0.4mm for the depression by indicating part number
FF5-6955-000 as usual in requesting the parts for your requirement. The service parts kept in stock in
the field are good quality parts with the deepness of 0.4mm for the depression.

The above two parts make the tolerance even less tight to handle copy paper with a large downward
curl. Replacing them at the same time the upper feed guide is replaced is not a requirement.
