SYMPTOM
Jam 033 (Fusing Exit Sensor)
CAUSE
The spring installed in the shaft assembly (D074 1405) to drive the fusing unit is not strong
enough and causes to the coupling separate momentarily, which temporarily slows down
the rotation of the fusing unit and delays paper transportation, resulting in Jam 033.
OCCURRENCE RATE
The occurrence rate is approximately 20%, which is a calculation based on units that
exhibited Jam 033 twice or more according to the @Remote data.
Jam033 is not necessarily a result of the aforementioned cause.
NOTE: All units manufactured prior to the modification are installed with the same spring.
However, this does not mean that all units will exhibit Jam033 because the jam is a
result of variances in the strength of the spring.
SOLUTION
A stronger spring was applied for the shaft assembly.
ACTION
Replace with the modified shaft assembly. Serial numbers of the affected units and the
replacement procedures are on the following pages.
