Hi
If you go to this page you get the option to download a manual for this machine in ZIP format, or to view the manual in your browser:
Aficio SP 3400N 3410DN download page
I suggest that you download the ZIP and expand it to your computer so that it is available for future reference.
The easiest way to get this onto your network would be to turn DHCP on, and let the printer get an IP address from the DHCP server on your network.
Otherwise you must find out the IP range for network, the Subnet address, the Gateway IP address, and the DNS server address, and enter them all onto the printer.
Hope this is helpful, if so would you please register that with Fixya
Cheers
