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.
3. Drag the Brightness slider to the left to make the item darker or to 
the right to make the item lighter. When you release the mouse 
button, the change is reflected in the preview item.
