Select the desired resolution.
resolution is a measure of how much image detail information
the scanner is to capture in a scan. A higher resolution results to a
sharper image but requires more disk space for file saving. for this
session, set the resolution to 300 dpi.
Execute the Scan Command
When you are finished with the control settings,
click on the scan button. the scanner begins to
scan the document and a message box appears
on the screen displaying the progress of the scan.
When the scan is finished, the image will be displayed in the main
screen of the host software.
Using Batch Scan
Batch scanning is an easy way to multi-scan any part
of your document using different scan modes and
resolutions. In batch scanning, you can specify up to a
maximum of 10 scan regions, or you can scan a single
region several times using different combinations of scan
modes and resolutions.
to activate batch scanning, click on the Batch scan
button. this will bring up the Batch scan dialog box
(ImageAcquire does not support the Batch scan).
