After a power outage the C3290 FS showed Controller Communication Error 117-313 Restart Printer.
Several attempts have been made but the error doesn't clear.
I had the same issue, right after power outage. Can't clear the error. Tried mulitple re-starts. I don't have the removable IP board either. So, now what?
After talking to FujiXerox support, I decided to scrap the printer and bought an Epson wifi printer for less than it would have cost to repair the other one.
