■GrayScale to scan items such as documents containing drawings or black and white photographs.

■Color to scan color photographs and other color items.

Resolution—Drag the slider to the right or left to adjust the dots per inch (dpi) of the resolution. The maximum resolution is 600 dpi; the minimum is 50 dpi. 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 and Contrast—Sometimes an item is scanned with the brightness and contrast set too light or too dark.

Brightness refers to the lightness or darkness of the image. Contrast is the range between the darkest and lightest portions of the image. The greater the contrast, the more difference between the lighter and darker shades in the image.
