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.
Pin No. In/Out Signal

CN15 CN15
Remarks
FSRFUSE 1 In Detects the fusing unit
CN15: On engine control board
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 [
!
] in the
fusing unit detects a sheet of paper [
$
]. The table lists the pin locations. (Refer to
illustration on pg. 6-29.)

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 [
%
] is rotating. While the encoder [
(
] is rotating,
the signal from the rotation sensor [ " ] on the fusing unit alternates. The encoder is
linked to the fusing belt shaft via gears. The table lists the pin locations. (Refer to
illustration on pg. 6-29.)
