Subject Measures against the J9000 Jam (No Original Feed Jam)
FS-C8020MFP, FS-C8025MFP, FS-6025FP, FS-6025MFP/B,
Model
FS-6030MFP
Phenomenon
The DP feed roller does not descend and the J9000 (No original feed jam) may appear.
Cause
If high stack of originals is forcibly pushed in, the stopper holding the leading edge of the originals hits the seal on
the top cover rib and sticks to it. If feeding from the DP is started in this state, the DP feed roller does not descend
enough, which causes J9000 (No original feed jam).
Corrective Measures
The seal affixed to the top cover rib on the machine rear side was removed in order to limit the adherence between
the stopper and the top cover rib.

Field Measure:
Please remove the seals affixed to the top cover rib at the machine rear side only if the phenomenon
described above appears.
(In order to maintain the stopper function, do not remove the seal on the machine front side which is same as
the one on the rear side.)
