Gathering Information on the Connection Setting

LAN connection information

• IP address

• Subnet mask

• Default gateway

Decide the IP address to assign to the printer.

When you assign the IP address statically, all values are required.

When you assign the IP address dynamically using the DHCP function, this information is not required because it is set automatically.

DNS server information

• IP address for primary DNS

• IP address for secondary DNS

These are required when specifying DNS servers. The secondary DNS is set when the system has a redundant configuration and there is a secondary DNS server.

If you are in a small organization and do not set the DNS server, set the IP address of the router.

Proxy server information

• Proxy server name

Set this when your network environment uses the proxy server to access the internet from the intranet, and you use the function that the printer directly accesses to the internet.

For the following functions, the printer directly connects to the internet .

• Epson Connect Services

• Cloud services of other companies

• Firmware updating

Port number information

• Port number to release

Check the port number used by the printer and computer, then release the port that is blocked by a firewall, if necessary.

See the following for the port number used by the printer.
