Selects the MTF filter coefficient in the main
scan direction when using grayscale processing
mode.
Select a higher number for a stronger filter.
If this is "0", the MTF filter is not applied
[0-15 / 0 / 1 step]
As above, for sub scan
[0-13 / 0 / 1 step]
Selects the MTF filter strength in the main scan
direction when using grayscale processing
mode.
Select a higher number for a stronger filter.
[0-7 / 0 / 1 step]
As above, for sub scan
[0-7 / 0 / 1 step]
Selects the smoothing pattern when using
grayscale processing mode.
A larger value could cause moiré to appear in
the image.
[0-7 / 0 / 1 step]
Selects the scanner gamma type when using
grayscale processing mode.
