E012-1080 due to the instable rotation of ITB drive (iPC8000VP)
[Symptom/Question]
E012-1080 may occur with the machines older than the following countermeasure cut-in serial numbers in factory.
- E012-1080: Drum ITB drive error
[Cause]
After some endurance time of the ITB, the load of the ITB drive drops. If the load drops more than expected, the rotation of the
ITB drive motor becomes unstable, resulting in the above-mentioned symptom.
[Remedy/Answer]
Referring to Service Manual (Error Code Details), perform the work stated.
If the above-mentioned symptom still occurs, replace the middle I.T.B. driver PCB assembly, with the new-type (FM1-A876-010)
(UN217) [1]. Update the Dcon firmware to Ver.20.23 or later at the same time. (Service Information (Software) Ref No:F02366)
[Reference] Replacing the middle I.T.B. driver PCB assembly with the new-type will not be effective, if the Dcon firmware is Ver.
13.02 or earlier.

[Factory measure 1]
Dcon firmware is updated to Ver.20.23 or later.
This will control switching the drive voltage of the ITB drive motor automatically for respective print speeds.
[Factory measure 2]
The middle I.T.B. driver PCB assembly is changed into the new-type (FM1-A876-010).
This will allow the drive voltage of the ITB drive motor to be changed for respective print speeds.
