Chapter 4 Scanner Operation
There are two types of application software interface to use with
the AV25 scanner. They are TWAIN and ISIS. TWAIN is the
most popular interface among image-editing application
software, while ISIS is most popular among archiving application
software (OCR).
Scanning Images from within an Application (TWAIN)
1. Open your application and choose Select Source from the
File menu. If the Select Source menu options are not
available from the File menu, see the user guide of your
application to learn how the TWAIN link is used.
2. A dialog box appears containing the different TWAIN
sources you can choose for bringing an image into your
application.
3. Select AV25/16 V3.2 as the source.
4. You need to select AV25 for just once except when you
have used the dialog box to select a different source. In
that case, you will need to select AV25 as the source again
before you can reuse the scanner.
5. Do calibration: Place a sheet of A4-size white paper in the
scanner and press the Calibration button to calibrate
“whiteness” for the scanner.
