Fs-3920 with envelope feeder and in envelope mode. Tray 1 has plain paper, tray 2 has letterhead.
How can I stop it from switching to tray 2 when tray 1 runs out. By switching paper type it stops and say's to release envelope mode levers.
The prescribe command R1 is gone.

I think I found my own answer, now I'll just have to go try it.
