ADJUSTING THE BRIGHTNESS AND CONTRAST

Sometimes an item is scanned with the brightness and contrast set to be too light or too dark. For example, a note written with a light pencil may need to be scanned darker to improve legibility.

You can adjust the brightness and contrast at which grayscale and color items are scanned. You can also adjust the brightness for black-and- white items. If an item is currently displayed in the preview area, the changes you make using the Brightness and Contrast control bars are reflected in the preview item.

To adjust brightness and contrast:

1.Click the Twain icon on the Command Bar, or choose Acquire from the File menu.

The Visioneer Scan Manager dialog box appears.

2.Click the Adv. Settings button on the Scan Manager. The Advanced Settings dialog box appears.
