SUBJECT: HOT ROLLER STRIPPER AND TENSION SPRING
SYMPTOM:
Paper jams in the Fusing Unit.
CAUSE:
When a mixture of the toner and paper dust accumulates on the tip of the Hot Roller Strippers, a gap
develops between the strippers and Hot Roller surface. Under this condition, the paper may not be
separated and may be caught by the tip of the Hot Roller Strippers causing a fuser jam.
SOLUTION:
To reduce the mixture of the toner and paper dust attracted to the Hot Roller Strippers, the material of the
strippers was changed. To increase the contact pressure between the Hot Roller and strippers, the tension
of the Hot Roller Stripper Springs was changed from 150 mN to 300 mN.
