Hello, I purchased a LaserJet 400 M401n with the optional 500 sheet tray ("tray 3"). I have placed the printer on the tray and filled it with paper. The internal "tray 2" has no paper in it. When paper is in tray 2, it prints fine. When paper is in tray 3 only, I get a "load paper" message. The printer does not appear to be recognizing tray 3. Does anyone know how to get this to work? Thank you.
