I'm having a bizarre problem with the ScanSnap 1300. I bought it the other day and installed it on my Mac Pro. For some reason, the OCR didn't work. Tech support advised me to remove all ScanSnap files (they gave me a list) and then reinstall ScanSnap manager. I removed all of the files on their list. But when I went to reinstall the program, I noticed that it said "upgrade" instead of "install". That's obviously a sign that the installer is still seeing some evidence of ScanSnap manager in my system. I went ahead and reinstalled anyways, and the OCR still didn't work. Then I tried installing ScanSnap on my MacBook. It said "install" rather than upgrade when I ran the installer, and sure enough OCR worked like a charm. This tells me that there's still some buried, hidden ScanSnap file on my Mac Pro that is mucking things up, but I can't find it. Fujitsu tech support isn't great with Macs, and they've escalated the issue to level 2 but I haven't heard back yet. Thought I might check here in the unlikely event someone else has experienced this.
