1. The LaserWriter 12/640 PS User's Guide on page 184 "Selecting the output tray" states: "You cannot direct the output to face-up when duplex printing. You cannot direct U.S. legal-size paper to the face-up output." The face-up tray cannot accommodate a legal-sized page. Because of this, it was decided that limiting the face-up tray for use with legal-sized pages would be a more elegant solution than having the paper fall off the tray.
2. We have verified this problem with the LW 12/640, and have reported it to engineering, however there is an easy workaround (see below).
Workaround
Temporarily adjust the 250-sheet cassette for Letter size and your print jobs will now exit on the face-up tray if you specify it as the output tray.
