Creases on the Fixing Belt
Expanded from heat under normal circumstances, the Fixing Belt shrinks slightly when it cools. The Tension
for the Fixing Belt is kept constant by the Tension Roller. When the Fixing Belt cools off, the portion of the
Fixing Belt which is in contact with the Tension Roller and the Fixing Roller hardens without shrinkage [1].
When the Fixing Belt begins to turn again, the portions of the Fixing Belt that were in contact with Tension
Roller and Fixing Roller move off the Rollers [2] and the Wrinkles appear on the Fixing Belt [3].
This symptom dissipates shortly after the Fixing Belt is reheated, and it continues to rotate. Therefore it does
not affect the Image Quality in a negative way. Consequently, replacement of the Fixing Belt is not necessary.
As these Wrinkles seldom cause any hindrance, inspect for other factors if an Image Quality or another Fixing
Issue arises.
