First thing you want to perform is a cold reset. Instructions are below.
Cold Reset
To perform a cold reset, turn the printer power off, then press and hold the JOB CANCEL
button. Turn the printer power back on and after all the LEDs come on release the JOB
CANCEL button.
You wait about 2 minutes after the printer comes to ready and then press the job cancel button and press the big go button and then release both which will now cause the printer to print a config page. The second page that comes out will be the network settings and will display the new ip address the printer found via bootp or dhcp. You can use this address to setup the printer. Changing the address to a manual address may be difficult since this printer probably has a jet direct 600N card whose web page requires older java code and will not work on most computers. You could try by typing in the ip address into you web browser and see if the web page comes up and if it does you can change the network settings to an address of your choice by choosing manual. If the card is a later card it should come up. Another method is to use the host name of the card when you add the printer instead of the ip address. The host name will start with NPI.
