Printer displays "Tray 2 Open" message.
Did the obvious...reseat tray 2, power cycled printer.
Discovered that the Op Panel was locked with this message.
Buttons did nothing.
Finally after another power cycle the error went away.
Googling and the manual show nothing. Even looked at schematics.
Couldn't find a "Tray 2 Open" mentioned.

ANY IDEAS??
