5. Select scan settings for the new scan configuration.
Mode—Select a scanning mode:
Black&White to scan in black and white. For example, letters and
memos are usually scanned in black and white. This scan mode
produces the smallest file size.
GrayScale 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.
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 maximum resolution is 600
dpi; the minimum is 50 dpi. 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 and Contrast—Sometimes an item 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.
Brightness refers to the lightness or darkness of the image.
Contrast is the range between the darkest and lightest portions of
the image. The greater the contrast, the more difference between
the lighter and darker shades in the image.
Drag the sliders to the right or left to adjust the brightness and
contrast of the scanned image. The Contrast setting does not
apply to the Black&White mode.
