Please open the front door and turn the blue lever in the middle,
remove the Transfer and Separation unit and check if the bushings of the transfer roller are damaged.
If OK, please give some oil on the shaft/bushings of the transfer roller. This unit may be replaced as a whole unit.
If SC401 re-occurs, please check the Photoconductor unit (drum).

The error sc 547 refers to a "Zero cross signal malfunction".
This means that the applied power supply AC frequency was detected at over 66Hz or below 45Hz, and the zero cross signals are not detected within a certain period within 500 ms after the main power switch has been turned on.
Possible causes are:
- Power supply board defective
- IOCSS defective
- BICU defective
Try to reset the SC code by entering SP5810 and select 1.
Then hold down the photo mode key and the # key at the same time for at least 3 second.
Then turn the machine off and on again.
If the same issue still appears, try to replace the Power Supply Unit.
