I just installed it tonight so haven't spent more than a few minutes with it, BUT is it all possible to print regular 20# paper from the back rather than from the tray? I was doing a setup of a greeting card program with 20# paper in the rear supply space, but it automatically drew paper from the tray. Does it depend on the weight of the paper? The reason I ask is because I don't have space in front of the machine to be pulling out the tray to insert just one sheet of paper. Perhaps I just need to do some more experimenting with it.
