I had my scanner working. I installed then uninstalled some software a PDFtoWord converter. Right after that my printer and scanner drivers stopped working. I got the Lexmark fixed by using the system environmental controls and adding some code. The scanner I have uninstalled, re-installed, still when I scan I get two errors 1 . "Unable to communicate with scan - check cables" (They're fine) 2. "Unable to open Twain source - check connection - re-start tool box". I'm lost as to what to do. Anyone here know?
