I have to say, I love that my Brother MFC-6490CW can scan to an ftp location. The downside is that it is not duplex enabled. So when I scan documents that have front and back, I need to scan the odd pages first, then the even. Leaving me with 2 pdf files. Searching for a way to merge them without buying some program turned out to be easier than I thought.
