SC559 is not issued unless SP1159 is switched on (Default: "0" off).
The fusing unit cover must always be opened and closed after this SC occurs to restore the
machine to full operation.
This ensures that the operator has opened and closed the cover to check for paper and/or
paper scraps around the hot roller. Loose paper around the hot roller is a fire hazard.
