Most of those features are implemented in the scan software on the PC, not on the scanner itself. Although there is a tendency to integrate more and more features in the firmware, which is not always a good idea. Also, if you’re scanning low volumes, I’d say doing the separation before the scan is generally more efficient. At least that’s how I do it. But that’s just me, of course. I wasn’t in any way trying to criticize your approach. If it works for you, it’s great.
