We just purchased a Phaser 7100 printer and it will not create an IP address. When I go to the network settings on the control panel of the printer and scroll through for IP address, it says it failed. It will not allow me to drill down on IPv4 and 6 settings. We tested the data cable and it works fine. The startup page shows the status as "obtaining IP address...". Is there a way to manually enter this information in? Did I purchase a lemon?
