If you cancel an in-progress scan from a third-party program that is obtaining images from a Windows Image Acquisition (WIA)-supported device, you may receive the following error messages:
Could not enable TWAIN source.
-or-
There is no scanner found.
NOTE: This behavior has been reported in third-party programs, such as, Picture Works PhotoEnhancer version 3.2, Adobe Photoshop, and CorelDRAW. Also, this behavior has been reported in Microsoft HomePublishing 2000.
In Windows 2000, this behavior does not occur: Programs do not generate errors when they are cancelled.
CAUSE
This problem can occur because the third-party programs are not properly handling the return value, which must follow the technology without an interesting name (TWAIN) specifications.
RESOLUTION
To work around this problem, close the dialog box that contains the error message, and then continue with your task.
Or, to resolve this problem, obtain updated drivers from the manufacturer of your third-party programs.
