3.18 Uneven image with approx. 60mm pitch in main scanning direction

 Description
There are some reported instances from the field where uneven image occurred with approx.
60mm pitch in main scanning direction due to 22/85T gear breakage in the primary fixing drive
assembly (FM2-2200).
 Field Remedy
2. Rotate only the primary fixing assembly manually, and check whether there are any areas
where it is not rotated smoothly during the rotation. If there are such areas, eliminate the
factors causing this symptom.
3. If such areas do not exist, check whether 22/85T gear [1] in the fixing drive assembly is
broken. If it is broken, replace the fixing drive gear assembly.
Reference:
From the following machine serial number, 22T/85T gear is divided into 2 parts. The material of
22T gear is changed from mold to iron.
