If a current leak occurs because of a small hole in the
fusing belt surface, the machine automatically turns this
SP off. After this, the fusing bias is not applied until the
fusing counter is reset and the SP is set back to ON or
the PM counter is reset.
•
0: OFF fixed
The fusing and discharge pin bias are always off.
•
1: ON fixed
The fusing and discharge pin bias are always on. It
only turns off when SC 420 occurs.
•
2: Auto
The fusing and discharge pin bias turns off after 2K
prints.
It also turns off when SC 420 occurs, even if the
number of prints is less than 2K prints.
It turns on after you install a new fusing unit and
reset the PM counter with SP7-804-7.
