black and white.
Grayscale to scan items such as documents containing drawings or black and white photographs.
Color to scan color photographs and other color items. Color scans have the largest file size.
•
Resolution—Drag the slider to the right or left to adjust the dots per inch (dpi) of the resolution.
The higher the dpi setting, the sharper and clearer the scanned image. However, higher dpi
settings take longer to scan and produce larger files for the scanned images.

•
Brightness—Sometimes an image is scanned with the brightness and contrast set too light or too
dark. For example, a note written with a light pencil may need to be scanned darker to improve
legibility. Increasing or decreasing the brightness makes the scanned image lighter or darker.

•
Contrast—The difference between the lighter and darker portions of the image. Increasing the
contrast emphasizes the difference between the lighter and darker portions, decreasing the
contrast de-emphasizes that difference.

•
Deskew—Select this option to let the scanner automatically determine if a page is skewed, then
straighten its image. If the page is fed through at too great of an angle, the image may not
straighten correctly. In that case, re-scan the page using the paper guides to feed the paper in
straight.

•
Filter—Filter is the ability of your scanner to automatically remove a color from a scanned image.
For example, if you are scanning a letter with a red watermark, you can choose to filter out the red
so the scanned letter just shows the text and not the red watermark. Color filter applies to Black &
White or Grayscale scanning modes.

scanned images of photographs or illustrations, particularly newspaper and magazine
illustrations. Selecting Reduce Moiré Patterns will limit or eliminate moiré patterns in the scanned
image. This option is only available at lower resolutions.
