Hi

Error code sc 547 means "Zero cross signal malfunction". This error appears due to a faulty power supply. This error code may also appear if the input board is defective or the BIC Unit is defective. Turn off the printer and unplug the printer for 30-40 minutes and check if the error still appears. If you see he error still appearing then try and rest it using the following reset method--
To reset the SC code by entering SP5810 and select 1.
Now 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, you'll need to check and replace the Power supply or the Input (IOCC) boardt.

Hope it helps...

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.

sc 990 relates to the nv ram chip on the main board also check the values of the lazer unit are correct and not changed

Zero cross signals are not detected within a certain period within 500 ms after the main power switch has been turned on.
Possible Causes
• Power supply board defective
• Noise on the ac power line
Try conect the copier in other side.
Disconnect all the household-electric of the place.

there may be a problem with your electric supply(wall outlet) , wrong voltage or power supply bad

The SP547 code is a fuser code and has to be reset in the service mode, it will not go away by turning the machine off and on. Check The lamp connections and trermistor connections .
