3. Appendix: SP Mode Tables
Black Display-Target
Displays the target value for the black-level adjustment executed during machine
4901 4
initialization. Normally, the value is 10. Other values indicate that the adjustment has ended
unsuccessfully.
White Target
4901 5*
Displays the target value for the white-level adjustment.

White Result
4901 6
Displays the result of the white-level adjustment.
White Display-Error
4901 8
Displays the return code of the white-level adjustment. When an error is detected, SC143
is generated.
White Display-Overflow
4901 9
Displays a return code of the white-level adjustment. The code "1" (error) is returned if the
adjustment result is not in the range of the values in SP 4901 6.
White Number of Attempt
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
4901 10
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 Setting
4901 11
Displays the parameter of the white-level adjustment. The value is based on the result of
SP 4901 12.
Auto Adjustment-Result
Displays the result of the white-level adjustment. Normally, the value is between 228 and
4901 12
281 (including the both values). When the value is normal, it is stored as the value of SP
4901 11.
