• the incorrect TWAIN driver has been selected
Each scanner model requires a specific TWAIN driver. If the TWAIN driver does not match the
scanner model, the AFHCAN software will bring up the Scan Failed message when you attempt
to scan.
The correct TWAIN driver is normally installed and tested when the scanner is installed.
Normally it should not need to be changed. However, if the Scan Failed message appears, you
will be invited to open a pop up window allowing you to select a different TWAIN driver.
Note: Selecting a new TWAIN driver typically would apply only
when a different model scanner is being installed.
Table 2 lists the scanner models and associated TWAIN drivers. (Other TWAIN driver options
may appear in the window that may not apply to scanners. Disregard any drivers not listed in
Table 2.)
