Diagnosing DTWAIN_TwainSave Problems

In some cases, a TWAIN device either fails to acquire the image, or some other error occurs that prevents the images from being acquired.  If problems persists, the first line of defense in diagnosing the problem is to use -verbose option.

The -verbose option will output messages to either the screen, or if the -verboselog is specified, to a file.  These messages will denote what operation DTWAIN_TwainSave is doing, and whether the operation was successful or unsuccessful.

The next, more detailed measure is to use the -diagnose option.  This will give much more low-level, detailed information as to what DTWAIN_TwainSave and your TWAIN device is doing during the acquisition process.  The information contained in the -diagnose log may be a little overwhelming, but it contains a wealth of information that can root out problems with either the way DTWAIN_TwainSave is operating, or how your TWAIN device is operating when asked to acquire an image or set of images.
