Fatal Error Messages
This section provides a description of error conditions that cause printing to stop. These errors are provided for information only. The corrective action in all cases is to first perform the reset function described in the Operator's Guide. If the printer reset does not solve the problem, cycle the printer power. If a reset or power cycle does not solve the problem, call your authorized service representative.
