•
Black&White
to scan in black and white. For example, letters and memos are usually scanned in
black and white.
•
Grayscale
to scan items such as documents containing drawings or black and white photographs.
• Color to scan color photographs and other color items. 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
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 —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 lighter or darker.
Contrast —The difference between the lighter and darker portions of the image. Increasing the contrast
emphasizes the difference between the lighter and darker portions, decreasing the contrast de-emphasizes
that difference.
Key and Lock icon—If you want to lock the configuration, click the key icon to change it from a Key to a
Lock.
