OKI C610 Printer getting 173:fatal error.

SOURCE: Oki C5200n 002: Fatal Error

We have to change firewall settings in our Fios router. I just don't know which ports or udp to open.

It points to an internal error. It may be from the fuser unit. Make sure all the wires are connected praoperly and that you didn't disconnect anything when you repalced the fuser. If the problempersists, you'll have to take it in for service.

That is a temperature error with the fuser, most likely the thermistor. Really the fuser needs to be replaced. Hope this helps.
