Measure 1
The bearing location of developing drive shaft has been shifted 1.0mm towards to the side of
developing assembly in order to ensure proper engagement.
When this issue occurs in the field, replace the developing drive shaft (FM2-2107) with a new
one. If the gear (FU6-0368) that engages with the developing drive unit is cracked, replace the
gear as well.
