5. SCANNER OPERATION
For TWAIN Application
AV500U allows you to operate the scanner from within a TWAIN or
plug-in software application. As the scanner driver is not a stand-
alone software, it has to be started from within a TWAIN/ISIS*-
compliant software application and then the scanner driver is able
to scan and load the image to your computer. The command to start
the scanner driver may vary due to different software applications.
To check the correct command, please refer to the user manual of
your software application.
5.1 USER INTERFACE OPERATION
1. Open your TWAIN scanning application.
2. Pull down the File menu and choose Select Source.
If the Select Source command is not available on the File menu,
see your application’s user’s guide to determine how the TWAIN
link is used.
A dialog box with a list of scanning sources appears.
3. Select the scanner.
You need to select the source only once, unless you want to
choose another scanner.
4. Place the document to be scanned in the ADF or on the flatbed
glass platen.
5. Pull down the File menu and choose Acquire.
A dialog box containing scanning features appears.
