The IP address makes no difference if you are local to the device, just login to it and change the IP address via Machine Status > Tools > Network Settings > TCP/IP settings
If you are remote and the machine is not online you can do nothing, call the location and give them a good IP/Subnet and gateway as well as those 4 selections to get them there.
Might not have chosen the best section to post this in but I wasn't sure where I should've.
I changed the IP address or our Xerox WC7845 printer, by accident.
And now I can't get into the settings anymore to change it back, and I dont want to do a factory reset since all our settings and preferences would get lost. Is there an easy fix?
