Try set the CAP_INDICATORS capability to the FALSE (see Strongly typed accessing to a capabilities )

CAP_INDICATORS

Description

If TRUE, the Source displays a progress indicator during acquisition and transfer, regardless of whether the Source's user interface is active. If FALSE, the progress indicator is suppressed if the Source's user interface is inactive. The Source displays device-specific instructions and error messages if either the user interface or progress indicator is turned on. In this case it returns TWCC_OPERATIONERROR to alert the application that it handled the error, and communicated the problem to the user. If both the user interface and progress indicator are turned off, then the Source never displays any message to the user, even if TWCC_OPERATIONERROR is returned. Messages to the user are under the sole control of the Application.

Application

If the application plans to enable the Source with TW_USERINTERFACE. ShowUI = FALSE, it can also suppress the Source’s progress indicator by using this capability.

Values

TWAIN 2.4 Specification 10-63
