Step Check Item Result Action
1 Check that each of the values displayed on the screen falls within the above range.
2 There is a wide difference between the
clamp and gain adjustment values, the
value being close to “0” or “255.”
YES Make positive connection of
the harness connectors
between CCD Sensor Board
and Image Processing Board.
3 Clamp adjustment value exceeds the allowable
range.
YES Reinstall covers, as extraneous
light is the cause of the
problem.
4 The lamp adjustment value or gain value
exceeds the upper limit of the allowable
range, being abnormally great.
YES Clean lens, mirrors, CCD surface,
shading sheet, and
related parts.
5 The lamp adjustment value or gain value
falls short of the lower limit of the allowable
range, being abnormally small.
YES Reinstall covers, as extraneous
light is the cause of the
problem.
Change Scanner, as the
reflectors are deformed.
