Summary: This all-in-one unit is replacing a problematic Brother unit we had and so far it has been a good purchase. We never have any jams or errors and we are putting through paper quantities near the top of it's suggested duty cycle. This is the first printer we've purchased that has the touch screen and it doesn't add anything special at least not that we utilize.
Summary: All applications work amazingly well but the paper tray is rather flimsy. The tray on cheaper models is more substantial. I thing that was a definite design flaw but time will tell if it will hold up.
Summary: I am using this printer over the network with machines running Ubuntu 12.04 and 12.10. It works very well (although I have not printed to fax). Printing is fast --- the first page typically takes just a few seconds --- and scanning over the network works on both machines. My only complaint (the reason I have docked a star) is that it took me a while to figure out installation for 12.04.
