Black Level
With this option you can set what the scanner should interpret as “black” in the final image. If you
are scanning items that have notes written with a pencil, you may want to raise the black level to
have the pencil notes appear black in the image. You can set a value for black from 0 to 127. If you
set this value to 127, you are telling the scanner that all pixels that are gray level 127 or lower
(darker) should appear as black in the final image.
