Print engine error codes

Engine error codes can be read either at the front panel or at the print engine
control board. The error code is displayed as a numeric value on the front panel.
A log of error codes is viewable in the menu item Service Support — Fault
History (fault 1 is the most recent). If, for any reason, the front panel is not
operating, you can interpret the current error code from a series of LEDs on the
engine control board.
