<Probable Causes>
• Leaked rays of light from LAMP1 through LAMP5
may be admitted into the scanner unit.
(Improper installation of the covers, damage
on the light-tight member located inside the
cover, etc.)
• The PMT08A board is faulty.
<Check and Reference>
• Check if an error (2545: HV voltage error 2)
occurs concurrently with the abnormal image.
Note, however, that it will not be detected if the
noise is minuscule.
<Probable Cause>
• Leaked rays of light externally coming into the
machine may fall on the scanner unit. (Improper
installation of covers to the machine, especially
the lower front cover, improper installation of the
light-tight members around the light-collecting
guide assembly, etc.)
