We had to take our 7900 down a set of stairs that was too narrow to allow a person on each side. That meant one person on each end. With one really strong friend on the lower end it went down one step at a time. The "normal" guy on the upper end could very briefly set the thing down on each step before hefting it to the next, but the other guy had to hold it up continuously, which was definitely not easy. There are 4 hand grips molded into the bottom of the printer, but those are useless if you can't have 2 people on each side as Epson recommends. Our path was a straight shot from outside and down a set of stairs into a large area, so the stairs were the only issue. A tight corner would be pretty bad.
