Why do you post HELP here?

Whoa, dude! Why not just set it to the correct paper size and break the knob off!

Wish I could - but these are leased units and we're paying the lease on them, so it would come out of my bill ... not theirs.

I had an idea just as I was logging off. Tell them you will "rent" them paper trays, "preloaded" with the correct paper and "preset" to the proper size, which will be labeled on the front of the tray in large, friendly letters. That way, they only have to insert the correct tray for the print job. When the preloaded tary runs out of paper, they call you and you replace it with another, for a healthy fee of course.

Now THIS idea I really like!
