impact (for example, when arranging sheets of copy papers)
<Symptom>
The upper feede r assembly sometimes opens when the user a rranges eje cted sheets of pape rs on the
feeder assembly on top of the Finisher.
<Cause>
The upper feeder assembly is held to the plate at the front o f the feeder assembly by 4 magnets, but

Servicing :
<Factory measure>
A check l ist at the source manufact urer for t he upper cove r has been expande d for rechecking of the
mold finish and whether the shape is free from faults.
<Affected machines>
From NLF00198 to NLF00229 Fr om ULF00048 to ULF00540
<Locating precisely where the problem occurs>
(Fig. 1)
Because of some faults with the shape of the
upper feeder assembly, two of t he 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
an impact.
These areas make
contact first.
