Solved! Go to Solution.
Just set the IP address on the printer to Static, doesn't matter what IP, just something, since you are not using the network it would appear, it simply can't find an IP address via DHCP, which is the defacto standard for just about any device, including this one.
@Xerox Support probably already sent those instructions, or soon will. But I will put them here too
Log on as admin and go to
Menu > Admin Menu > Network Port > TCP/IP Settings > Ethernet > Get IP Address > Static > IP Address
Since you don't have it on the network, the settings don't matter beyond needing to look real, so 10.10.10.10 can be the IP qand the gateway. 255.255.255.0 would be fine for the subnet mask
