2.Symptom:
In rare cases, the bearing fitting parts on both sides of the fusing rear follower roller in the
paper ejection/inversion unit may suffer thermal deformation with elapse of time. This may
result in jam (POD1S, etc.) or abnormal sound (rattling sound) during paper ejection.

result in jam (POD1S, etc.) or abnormal sound (rattling sound) during paper ejection.
3.Description:
To improve thermal deformation of the fusing rear follower roller with elapse of time, the bearing
fitting parts on both sides of the roller are eliminated, and their material is changed. (The
material is changed from POM to PET.)
