printer displays WARNING or POWER DOWN on the top line of
the keypad display.
If this happens, record the displayed message and turn off the
printer. If the problem reoccurs when you turn the printer on
again, call Technical Support.
If the problem does not reoccur after you turn your printer on
again, reset your printer’s SETUP options. Retransmit your
