Adjusting Scanner Settings
Overview
The Scanner Image Control window allows
control over scanner settings. For all scanners, contrast,
resolution, paper size, output format, page orientation, and page
type can be adjusted. Certain scanners have additional image
processing capabilities which are not available on all models.
These advanced capabilities include bar-code recognition, patch
code recognition, skew detection and removal, image crop, and
annotation.
Procedure to Adjust Scanner Settings Common to All
Devices
NOTE: The available ranges
or values for these controls can vary, based upon individual
scanner capabilities. Be aware that changing the scanner type may
invalidate some of these settings.
-
Click on the [Image Control] button to open
the Scanner Image Control window.
-
Contrast - Selects the image contrast on a
uniform, scanner independent scale. Choosing a lower value will
lighten the image and choosing a higher value will darken the
image. Scanners with built-in automatic contrast control may ignore
this setting unless that feature is disabled.
-
Resolution - Selects the resolution of the
image in dots per inch. Some scanners will not support all values
that appear in the drop-down list. 200 dpi is an industry-wide
standard for black and white archived documents and 300 dpi is used
occasionally for detailed work, barcoding, and optical character
recognition. Higher values result in a substantially larger file
size on disk with a negligible gain in quality.
-
Paper Size - Selects the size of the
documents being scanned without respect to orientation. This
setting should match or exceed the physical dimensions of the
material being scanned. The resulting image will be exactly this
dimension, including any annotation.
-
Page Orientation - Selects the orientation
of the information on the pages being scanned.
-
Portrait orientation is when the top and
bottom of the image are the short dimension of the paper size.
-
Landscape orientation is when the top and
bottom of the image are the long dimension of the paper size.
-
Rotated Portrait is available on certain
scanners with wide feeders to allow the paper to feed sideways
through the mechanism, thus reducing the time for each page to be
scanned.
-
Page Type - Selects single or double sided
scanning. The scanner must support duplex scanning if double sided
is selected. In double sided mode, two images will be saved for
each physical page scanned.
-
Output Format - Selects the image file
format. Available formats depend on the scanner interface being
used.
-
[Advanced Scanner Features] - Additional
processing features are available inside Image-Master when a Kofax
interface card is used in conjunction with a scanner.
-
[Test Scan] - Choosing this button causes a
single page to be scanned from the scanner and displayed in the
viewer using the current settings as described above. Any job in
progress is unaffected by this operation except that pages fed
through the document feeder will have to be returned to the input
tray prior to the resumption of the scanning job. Use this feature
to verify that the chosen image control settings produce the
desired results.
-
[Save] - Keeps the new settings.
-
[Cancel] - Abandons all changes.
-
If the [Save] button is selected, the
Save Settings dialog box opens:
-
[This Session Only] - Settings are saved for
use in the current scanning session only. These settings will be
discarded, and the default settings reloaded as soon as the
Scanning Module window is closed.
-
[Make Settings Permanent] - Settings are
saved as the default settings for the current image database and
will apply to the current session.
-
[Cancel] - Abandon all changes to the
settings and return to the Scanning
Module window.
