SC559 Detect
1913
This SP setting determines whether SC559 is issued after three paper late
jams occur in the fusing unit. After this SP code is turned on, a counter
monitors the number of paper late jams that occur in the fusing unit. After
the 3rd occurrence of a fusing jam, SC559 is issued and the machine
cannot be used until the service technician releases the error.
Note: Switching the machine off/on does not reset this jam counter. The
counter is reset after the cause of the jam has been removed and a sheet of
paper successfully passes the fusing exit sensor.
