Service Bulletin COPIER
Issued by Canon Europa N.V.
Model : Finisher D1 No.: Acc-155
(FF-T01-W-000053-01)
DATE: 07.05.99
Location : UPPER FEEDER ASSEMBLY
Subject : Countermeasures to prevent the upper feeder assembly of the Finisher D1 from opening on impact
Reason : To communicate countermeasures (in connection with servicing the machine) to be taken for the
possibility of the upper feeder assembly opening when the upper part of the Finisher receives an
impact (for example, when arranging sheets of copy papers)
Details :
The upper feeder assembly sometimes opens when the user arranges ejected sheets of papers on the
feeder assembly on top of the Finisher.
The upper feeder assembly is held to the plate at the front of the feeder assembly by 4 magnets, but
the 2 magnets on the inner side float up due to poor molding procedure of the part into shape, and the
cover opens due to insufficient magnet strength.
A checklist at the source manufacturer for the upper cover has been expanded for rechecking of the
mold finish and whether the shape is free from faults.
Servicing :
From NLF00198 to NLF00229 From ULF00048 to ULF00540
(Fig. 1)
Because of some faults with the shape of the
upper feeder assembly, two of the shaded areas
(out of the four locations for the magnet catches)
make contact first, causing a difference of
approx. 0.25 to 0.5mm. This results in weaker
contact for the other two areas, and the problem
of upper feeder assembly to open from receiving
These areas make
an impact.
