scans have the largest file size.
Resolution—Drag the slider to the right or left to adjust the
I
dots per inch (dpi) of the resolution. The maximum resolution is
1200 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
I
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 the 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.
