SYMPTOM
Jam097 (Over skew) or Jam098 (Over shift) occurs when paper size less than A4 (SEF) is
scanned by the CIS.
CAUSE
The light amount is less at the center because inside the CIS gets cloudy due to degradation of
the adhesive agent inside the device.
NOTE:
When paper size more than A4 (SEF) is scanned by the CIS, this error may not occur because the
CIS scan works outside the cloudy area of the CIS.
SOLUTION
Since the CIS device cannot be disassembled to remove the cloudy area, adjust the amount of
light used for scanning, by following this procedure.
1. Remove the dust removal cover. (TCRU screws X 3)
