Fusing unit detection
The fusing unit detection signal FSRFUSE indicates that the fusing unit is installed.
The circuit closes when the fusing unit connector is properly seated. The table
below lists the pin location.

Paper jam detection
The paper jam detection signal NFSRJAM indicates that a paper jam has occurred
in the fusing unit. The circuit is closed if the paper jam detection sensor [

Rotation detection
The encoder monitors whether the fusing belt is rotating. If the fusing belt breaks,
the encoder will not detect any rotation. The fusing belt rotation signal ROTATE
indicates whether the fusing belt [
