4901 10 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 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.
4901 11* Auto Adjustment Setting
Displays the parameter of the white-level adjustment. The value is based on the
result of SP4-901-12.
4901 12 Auto Adjustment-Result
Displays the result of the white-level adjustment. Normally, the value is between
228 and 281 (including the both values). When the value is normal, it is stored as
the value of SP4-901-11.
4901 14 Auto Adjustment-Error
Displays a return code of the white-level adjustment. The code "1" (error) is
returned if the adjustment result value is less than 228 or larger than 281 (
901-12).
4902* Exposure Lamp ON
4902 1 Turns the exposure lamp on or off. To turn off the exposure lamp, select "OFF".
(The exposure lamp shuts off automatically after 180 seconds.)
4903* ADS Level
4903 1 Adjusts the ADS level.
4904* ADS Lower Limit
4904 1 Adjusts the ADS lower limit.
4905* ADS Level
