We recently purchased a Bizhub C350 and I cannot seem to find the options where to confgure the network settings. It's currently set to DHCP which is working fine. I tried on the Printer itself and through IE but I does not display ANY advanced features, even with the Admin Mode and password.
Does the screen say 'power on controller' if so the controller is turned off or it has been removed and the machine is configured for a fiery. Otherwise just click some of the options on the screen the IP stuff will appear eventually this is a 'feature' of the internal controller.
are you using the latest version of firmware?
if yes, try to install driver of impression in another tcp/ip port
if not, make the update firmware and try again install driver of impression in another tcp/ip port
