Is the stairwell out of the question? How many floors up is it going? I know it's not ideal, but even taking the end covers off, there isn't anything to support the weight of the machine on the ends. Plus, on one side you have your service station/print carriage and the other your ink supply. I'd be very hesitant to tip it on the end. I used to work for a moving company, and we'd move all sorts of things up the stairs if we couldn't get it to fit in the elevator. Perhaps, there is a local moving company you could ask for a quote on moving it for you.
