Moiré Reduction
Moiré patterns are wavy or rippled lines that may appear in the scanned images of newspapers and magazines, and sometimes scanned images of photos, line drawings, and color scans of textured paper. Select the Moiré reduction option to have the driver attempt to find and remove moiré patterns from the image. Please note that when Moiré reduction is enabled the scanner may scan slower as the image is checked for moiré patterns. This option is only available when scanning in Color or Gray.

For the best automatic results you can simply select the type of paper you are scanning from the list. Alternatively, you can input a number in the Custom value field. The value you set in this field can be from 128 to 255. If you set the custom value to 128 you are telling the scanner that all pixels that are grey level 128 or higher (lighter) should be changed to white in the final image. If you set the custom value to 255, you are telling the scanner that only pure white is white and anything lower than 255 should remain unchanged in the final image.
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 grey level 127 or lower (darker) should appear as black in the final image.
