    You should change the fixing drive unit (ref: RM1-4974-000)

    Just wanted to update this thread to state that updating to the latest firmware made the issue go away, as suggested above (7.10).

    Thanks to "wav" who was able to help me with this.

    Attention!!




    A skilled technician is needed for disassembly and assembly. Ordinary personnel should pay attention to disassembly and assembly, as the drive clutch is located inside the drive gear.



    After removing the cover on the right side of the machine from the front, you can see a drive clutch. The softening of the clutch release sponge caused the machine to have inaccurate calibration between the drive drum and the ITB component color block sensor, resulting in malfunction.


    The method is very simple: remove the clutch, remove the softened sponge, replace it with a layer of electrical tape and install it to solve the problem.
