SCANNER SERVICE MODE
Function and [Setting]
Adjusts the image density for each image
density level for Text mode when using binary
picture processing mode.
[0-255 / 128 / 1 step]
[0-255 / 100 / 1 step]
[0-255 / 128 / 1 step]
[0-255 / 128 / 1 step]
[0-255 / 85 / 1 step]
[0-255 / 128 / 1 step]
[0-255 / 128 / 1 step]
[0-255 / 70 / 1 step]
Selects the independent dot erase level.
With a larger SP setting, more dots are detected
as independent dots and erased.
If this is "0", independent dot erase is disabled.
[0-7 / 4 / 1 step]
Selects whether the unevenness correction is
done.
This function is like an FCI function. If this is "1",
the edges of characters in scanned images will
be smoothed.
[0: OFF, 1: ON]
Selects the MTF filter coefficient in the main
scan direction for Text/Photo mode.
Select a higher number for a stronger filter.
If this is "0", the MTF filter is not applied.
[0-15 / 4 / 1 step]
As above, for sub scan
[0-13 / 4 / 1 step]
Selects the MTF filter strength in the main scan
direction for Text/Photo 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/Photo
mode when using binary picture processing
mode.
A larger value could cause moiré to appear in
the image.
[0-7 / 0 / 1 step]
