Measures against 012D jam occurrence
[Symptom/Question]
012D jam may occur with the machines earlier than the following countermeasure cut-in serial numbers in factory.

the shaved shaft with the new type, and apply super lube grease. When replacing the shaft, it is recommended to replace the
ball bearings that are in contact with the shaved shaft, at the same time.
