The code means:
E197 0000 Printer engine communication error
Erroneous communication between the DC controller PCB and
image processor PCB was detected.
- Check the connectors of the DC controller PCB and image
- Replace the DC controller PCB for normal connection.
- Replace the image processor PCB.
What I've seen is that code comes up occasionally and can be reset by turning the copier off and on again. Bad input power caused this. Check the power from the outlet and also check to see if you have a good ground. If your problem ends up being power.....call an electrician or plug it into another outlet that tests ok - do this before a board gets damaged and you end up with a code that cannot be reset and have to replace one or both of the boards mentioned above.
