Re: And yet...
I have an inkjet because it was by far the cheapest way of buying a scanner with an automatic "document feeder. Sometimes inkonomics works in your favour."
Does the scanner work when one or more ink carts are empty? If not, how much ink is wasted by cleaning, even though you may never use it as a printer. There are some models which fail completely when the ink runs out, but most commonly, printers that won't print monochrome even when the black is full but any one or more of the colours are low/empty.
