Chapter 4 More Sophisticated Fault Isolation Tasks
3-17
Cause Point to check Action
C1 Check to see if the cutter has not loosened out of position. Mount.
C1
Check to see if there is not any foreign matter stuck in the cutter blade lowering
mechanism (iPF700, iPF8000 Series).
Remove.
C1
If non-recommended paper (paper thicker than recommended, canvas paper, cloth) has
been used, check to see if a recommended paper equivalent can be cut.
Explain.
C1, C2, C3 None of the above Flow 1
Temporary
measure
If paper cannot be cut in a high-duty printing operation only, reducing the cutting speed may make the
paper is easier to cut.
Temporary
measure
Film-based paper will be made easier to cut if the “Reduce Cutting Dust” mode is selected, but its
execution would leave ink marks on the cut surface.
10. 【2015】Cutting failure (Cannot cut sheet)
Occurrence
conditions
The multisensor has detected paper that is not supposed to exist, after cutting paper.
C1 Cutting failure
Faulty/loose cutter
Deformed/flawed lower blade of the cutter
Run over thick paper (cloth)
Lifter operational failure (iPF5000 Series)
Low suction fan suction force
Faulty cutter blade lowering mechanism of the cutter (iPF700, iPF8000 Series)
Incorrect paper choice
C2 Ejection failure Residual/stuck paper
Failure causes
C3
Cannot rewind
paper
Jam
Is paper cut properly?
Is there residual paper
left on the platen?
Remove the residual paper
Yes
No
Sticking caused by static
electricity
Dirty platen
Obstacles before the paper
ejection unit
Paper rewinding failure
Yes
Feed paper manually
and perform Forced
Cut
No
Is the cutter blade
down?
Check the cutter blade
lowering mechanism for
successful operation
Faulty cutter
Foreign matter in the
lowering mechanism
No
Yes
iPF700 Series
iPF8000 Series
iPF5000/iPF800 Series
Replace the cutter (upper
blade)
Are there marks of the
upper blade riding
over the lower blade?
Replace the upper and
lower blades
Are platen suction
holes clogged?
No
Yes
Remove clogging
Yes
No
