CÓPIA NÃO CONTROLADA
Selects the MTF filter strength in the sub scan
direction for Text/Photo mode.
Select a higher number for a stronger filter.
[0~7/2/1]
Selects the smoothing pattern for Text/Photo
mode.
A larger value is smoother. A smaller value
could cause moiré to appear in the image.
[0~7/0/1]
Selects the scanner gamma type for
Text/Photo mode.
[0~7,11/6/1]
0:Normal, 1:Smooth, 2:Distinct, 3:Sharp,
4:Text, 6:Text/Photo, 7: Photo, 11: Grayscale
4~7 is used for delivery scanner mode.
The following SPs adjust the image density
(brightness, contrast, and thresholds) for each
image density level (from 7 to 1) for
Text/Photo mode. The settings are reflected in
the gamma table.
[1~255/128/1]
Selects the MTF filter coefficient in the main
scan direction for Photo mode.
Select a higher number for a stronger filter.
If this is "0", the MTF filter is not applied.
[0~13/0/1]
Selects the MTF filter coefficient in the sub
scan direction for Photo mode.
Select a higher number for a stronger filter.
If this is "0", the MTF filter is not applied
