Enable Extended Capabilities
TwainPRO 9 for ActiveX - User Guide > How To > Open a TWAIN Session > Enable Extended Capabilities

Some non-compliant TWAIN drivers don't properly handle a query for support of extended capabilities (CAP_FEEDPAGE and CAP_CLEARPAGE).

If you do not plan to use these capabilities, set EnableExtCaps to False.

The Data Source should be set before opening a TWAIN session (OpenSession).
