The scanner returns X'0001 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000'. (00 only)
-Image control function: Bytes 52 to 57
- Indicates supplementary information for parameters defined in the SET WINDOW command.
a)Brightness steps: Byte 52
Indicates the brightness level. X'00' indicates that the brightness function is not supported. The scanner returns X'FF'.
b)Threshold steps: Byte 53
Indicates the threshold level. X'00' indicates that the threshold function is not supported. The scanner returns X'FF'.
c)Contrast steps: Byte 54
Indicates the contrast level. X'00' indicates that the contrast function is not supported. The scanner returns X'FF'.
d)Reserved: Byte 55
