ADJUSTING COLOR AND GRAY IMAGES

The Scan Manager has three buttons—Descreen, Sharpen, and Auto Level—for quickly adjusting color and gray images. These buttons do not apply to black and white or halftone images.

Descreen

Sharpen

Auto Level

DESCREEN IMAGE

Select this option when scanning a picture from a newspaper or magazine article, sales catalog, or other source that contains images with patterns or dots. Scans of patterns or dots sometimes have a distorted or wavy appearance. The scanner scans the item to compensate for the patterns and dots, and produces a clearer image. The scanning may slow down a bit when this option is selected. You don’t need to select this option when scanning photographs.
