Scanning Items

• 8-Bit Gray—scans the image using up to 256 true shades of
gray. Use this setting to scan black and white photographs and
other higher quality black and white images. You can also scan
a color photo with this setting to turn its colors into gray shades.
The file size is about one third the size of a color scan.
• 24-Bit Color—scans the image in full color. Use this setting to
scan color photographs and other color images. The file size is
the largest of the image type options.
NOTE: You can see the file size at the bottom of the Scan
Manager.
Resolution
Resolution determines the amount of detail you can see in the
scanned image. The resolution setting for a scan is in dots-per-inch
(dpi). The higher the resolution, the finer the details, however,
higher dpi settings also take longer to scan and produce larger files
sizes. Higher settings are typically used for precision work, such as
photographs or fine artwork.
• Click the Resolution drop-down list and select a resolution.
The resolution settings on your DocuMate 510 scanner range
from 100 dpi to 2400 dpi.

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 the difference
between the lighter and darker shades in the image.
• Dark/Light slider—adjusts the brightness of the scan. Drag
the slider to the right or left to increase or decrease the
brightness.
• Low/High slider—adjusts the contrast. Drag the slider to the
right or left to increase or decrease the contrast.
