Function and [Setting]
Selects the MTF filter coefficient in the main
scan direction for Text mode.
Select a higher number for a stronger filter.
If this is "0", the MTF filter is not applied.
[0-15 / 7 / 1 step]
As above, for sub scan
[0-13 / 6 / 1 step]
Selects the MTF filter strength in the main scan
direction for Text mode.
Select a higher number for a stronger filter.
[0-7 / 5 / 1 step]
As above, for sub scan
[0-7 / 5 / 1 step]
Selects the smoothing pattern for Text mode
when using binary picture processing mode.
A larger value could cause moiré to appear in
the image.
[0-7 / 0 / 1 step]
Selects the scanner gamma type for Text mode
when using binary picture processing mode.
[0-6 / 4 / 1 step]
Adjusts the image density for each image
density level for Text mode when using binary
picture processing mode.
