Below is an example of a color scan, a black and white scan without dithering, and a black and white scan with
dithering. When the image is scaled down, it may look like a grayscale scan. When the image is at normal size or
enlarged you will be able to clearly see the dithering pattern, as shown in the close-up image.

Mixed Content Options (Text and Graphics)
The Bit depth reduction list includes automatic separation options for mixed content documents containing both
text and graphics. These options enable the scanner to evaluate the image for text and graphics, and then apply
threshold to the text regions and a dither pattern to the graphics regions. This retains text clarity while providing
graphic legibility.
The mixed content options are:
• Threshold – Diffusion
• Threshold – Bayer
• Threshold – Halftone
Fill Margin Holes
Select this option if you are scanning pages with punched holes in the margins. This option will fill these holes with
the detected background color in the final scan. The scanner will detect and fill the holes under the following
conditions:
• The size of the hole can be between approximately 4 mm and 12 mm
• The maximum width of the margin is 25.4 mm from the edge of the paper
• The size of the margin is 24.4 mm
