User's Manual

• 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.)
