Turn the printer off and then on. When the printer begins its memory count, press and hold down the Green button until all the main LED signal lights illuminate and stay illuminated. Then release the Green button, and use the Up/Down arrow keys to find the Cold Reset option, then press the Green button again to choose that option.

You will then need to setup your I/O again. Change TCP/IP to static and setup an IP.
