adjustment result is not in the range of the values in SP 4901 6.
4901 10
White Number of Attempt [0 - 20 / 0 / 1/step]
Displays how many times the white-level adjustment is retried. The value does not include
the first execution of the white adjustment. For example, if the value is "2", this indicates
that the white-level adjustment has been executed three times. The white-level adjustment
can be executed
20 times or less. Therefore, if the value is "20," this indicates that the white-
level adjustment has ended abnormally (as described, the value "20" does not include the
first execution). If the white-level adjustment is unsuccessful, the machine uses the result of
the latest, successful white-level adjustment.

Auto Adjustment-Result [0 - 600 / 0 / 1/step]
Displays the result of the white-level adjustment. Normally, the value is between 228 and

4901 11.
