This setting controls whether the client attempts to delay and force the scanning process to time out. This can be useful for certain types of scanners that do not properly notify the client that the scanning process has finished.
If TwainForceTimeout is set to 0, or if no value is present, then the client only ends the scanning process when the scanner determines that the process is complete. This is the default setting.
If TwainForceTimeout is set to 1, then the client attempts to delay and force the scanning process to time out.
