Scanning from PaperPort The PaperPort TWAIN interface opens. Use it to select scanning options and to start the scanner. The options on the Xerox DocuMate 152 TWAIN interface are: • Mode-Select a scanning mode: Black&White to scan in black and white. The scanning pixels are all the same size and are either black or white. Use this setting for letters, memos, and other black and white material. This scan mode produces the smallest file size. GreyScale to scan items such as documents containing drawings or black and white photographs. The scanning produces an image of up to 256 shades of gray. You can also scan a color document to turn its colors into gray shades. The file size is about one third that of a color scan. Color to scan magazine articles, photographs, and other color images in full color. 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 maximum resolution is 600 dpi; the minimum is 50 dpi. This option determines the amount of detail you can see in the scanned image. 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. Usually the higher resolution settings are used for precision work, such as photographs or fine artwork. • Brightness and Contrast-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 DocuMate 152 Scanner User's Guide 87
