Is there network card is installed in it, if yes then you can configure it with your network go to machine Manu in machine control panel and the in network settings here you can give the IP address and subnet mask after then reboot the machine.
If network card is no installed behind the machine then you can use its built-in USB or and parallel printer without NIC card.

To scan to email, Administrator email address must be set in the machine (any bogus email address will work too).
Also, email server address must be input as IP address if DNS or WINS is not running in LAN.
