Fusing Jam Detection

SC Code Display
[0 to 1 / 0 / 1] 0:OFF, 1:ON
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.
D009/D011/D012/D013
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.
