1. Turn the printer off.
2. Get an ethernet cable and plug the printer into your LAN.
3. Turn the printer on, give it a minute to start up.
4. Press and hold the printer's STOP button for about
5 seconds. It should cause the printer to print out its Network Configuration Report. (Note: This is different from the Demo page, which will print if you hold down the STOP button for 2 seconds instead of 5 seconds...)
5. On this report, look for the printers IP Address (i.e. 192.0.0.192)
6. Fire up any web browser and point it to that address:
http://192.0.0.192
You should be able to configure any of the settings you want using that webpage. Also, you can reset the printer to its factory defaults if you prefer.
For your reference, here are the manuals for that printer in case you want more info. They will basically tell you to do the same thing but will use a lot more words to do so.
