After you press the Scan button on a Fujitsu ScanSnap, a progress window pops up showing you what the scanner is doing.
If you, for whatever reason, don’t want that to happen, you can turn that progress window off on the Mac.
Over on the ScanSnap Community, they have a helpful tutorial for toggling this behavior:
How to Do Background Scanning on a Mac.
Although active windows are great to show the scanning progress sometimes they can get in the way of your work flow. There is a quick and easy way to deactivate the pop-ups on your Mac just by changing a couple of settings.
I think I still like to see what is going on, but that’s a great little hidden setting if you want to keep things a bit more quiet.
