Hello, FK3 is not an error message, but a maintenance message. It's telling you that the fuser web needs to be replaced. Generally when it's time to replace the web it's also time to do other maintenance, so check the machine's maintenance counters to see what other codes might be showing up. (The FK3 is the only one on the screen, but there may be other codes "behind" that one.)
