SUBJECT: FUSING UNIT DAMAGE
SYMPTOM:
The Fusing Unit is damaged by the Pick-Off Pawls.
CAUSES:
There are three possible causes:
1. Pick-Off Pawls:
When a paper jam occurs in the fusing unit, paper may push the pawls up or down against the fusing
belt or pressure roller, causing the belt or roller to be damaged by the pawls.
2. Fusing Belt:
The fusing belt layer may peel off from the base layer during a print run due to an insufficient amount of
adhesive applied.
3. Oil Supply Unit:
The oil supply unit deforms due to heat from the fusing unit, causing the oil not to be applied evenly to
the fusing belt. This may cause a paper jam or the oil supply roller to become dirty with toner.
SOLUTIONS:
Production line
1. Pick-Off Pawls
The edges of the pawls have been rounded to minimize belt or roller damage with a paper jam.
2. Fusing Belt
The amount of adhesive has been increased and is more evenly applied to the base layer.
3. Oil Supply Unit
A metal plate will be added underneath the oil supply felt to ensure the unit does not deform.
