I have the same problem. PaperPort can scan fine, everything in windows sees the scanner. Some service or something is not running correctly on the windows computer, but I don't know what. Restarting always fixes the problem, but listen - Xerox - I can't restart my computer everytime I need to scan something because your crappy service keeps dying!
What's going on?
Windows 7 PC here... Anyone know what service it's supposed to be?
