Cannot Select TWAIN Source

Problem: AS4A will not auto select TWAIN source from drop down menu
Reason(s): Scanner not plugged in, conflict of TWAIN sources in Twain_32 folder
Solution(s): Confirm scanner plugged in. Fix Twain_32 folder.

Steps: 

  1. Close AS4A via Task Manager
  2. Confirm scanner is plugged in to USB port. If it is, try another port.
  3. Relaunch AS4a

If that does not correct:

  1. Close AS4A via Task Manager
  2. Go to C:\Windows\twain_32
  3. Cut and paste all non-Ambir folders on to the desktop (do not delete). Leave Ambir folders in that location.
  4. Relaunch AmbirScan for Athena. The Twain driver should now be selected
  5. Cut non-Ambir folders from desktop and paste back into C:\Windows\twain_32
  6. Relaunch AS4A to ensure the correct device is selected.
