Network Connection

This is an example of connecting a printer to a network. Functions and services that are not available in your product may be included.

Before Making a Network Connection

To connect to the network, check the connection method and setting information for connection in advance.

Gathering Information on the Connection Setting

Prepare the necessary setting information to connect. Check the following information in advance.

Divisions	Items	Note
Device connection method	Ethernet Wi-Fi	Decide how to connect the printer to the network. For Wired LAN, connects to the LAN switch. For Wi-Fi, connects to the network (SSID) of the access point.
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.
Wi-Fi connection information	SSID Password	These are the SSID (network name) and the password of the access point that the printer connects to. If MAC address filtering has been set, register the MAC address of the printer in advance to register the printer. For the supported standards, see the User's Guide.
DNS server information	IP address for primary DNS IP address for secondary DNS	These are required when assigning a static IP address to the printer. 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. The printer connects directly to the Internet in the following cases. Firmware updating Using Epson Cloud Solution PORT functions
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. For the port number used by the printer, see the Appendix.

IP Address Assignment

The IP address assignment types are described below.

Static IP address:

A predetermined fixed IP address is assigned to the printer (host) manually.

The information to connect to the network (Subnet Mask, Default Gateway, Primary DNS, Secondary DNS) needs to be entered manually.

The IP address does not change even when the device is turned off, so this is useful when using devices an environment where you cannot change the IP address or you want to manage devices using in the IP address. We recommend settings to the printer, server, etc. that many computers access. Also, when using security features such as IPsec / IP filtering, assign a fixed IP address so that the IP address does not change.

Automatic assignment by using DHCP function (dynamic IP address):

An IP address is assigned to the printer (host) automatically by the DHCP function of the server or router.

The information to connect to the network (Subnet Mask, Default Gateway, Primary DNS, Secondary DNS) is set automatically, so you can easily connect the device to the network.

If the device or the router is turned off, or depending on the DHCP server settings, the printer's IP address may change when reconnecting.

We recommend managing the device using a method other than the IP address and communicating with protocols that can follow the IP address even if it changes.

Note:

When you use the DHCP IP address reservation function, you can assign the same IP address to the devices at any time.

DNS Server and Proxy Server

The DNS server has a host name, domain name of the email address, etc. in association with the IP address information.

Communication is impossible if the other party is described by host name, domain name, etc. when the computer or the printer performs IP communication.

The DNS server queries for that information and gets the IP address of the other party. This process is called name resolution.

Therefore, the devices such as computers and printers can communicate using the IP address.

Name resolution is necessary for the printer to communicate using the email function or Internet connection function.

When you use those functions, make the DNS server settings.

When you assign the printer's IP address by using the DHCP function of the DHCP server or router, it is automatically set.

The proxy server is placed at the gateway between the network and the Internet, and it communicates to the computer, printer, and Internet (opposite server) on behalf of each of them. The opposite server communicates only to the proxy server. Therefore, printer information such as the IP address and port number cannot be read and increased security is expected.

When you connect to the Internet via a proxy server, configure the proxy server on the printer.

Connecting to the Network from the Control Panel

Connect the printer to the network by using the printer's control panel.

For the printer's control panel, see the User's Guide for more details.

Assigning the IP Address

Set up the basic items such as Host Address, Subnet Mask, Default Gateway.

This section explains the procedure for setting a static IP address.

Turn on the printer.
Select Menu on the home screen on the printer's control panel.
Select General Settings > Network Settings > Advanced.
Select TCP/IP.
Select Manual for Obtain IP Address.

When you set the IP address automatically by using the DHCP function of router, select Auto. In that case, the IP Address, Subnet Mask, and Default Gateway on step 6 to 7 are also set automatically, so go to step 8.
Enter the IP address.

Focus moves to the forward segment or the back segment separated by a period if you select and .

Confirm the value reflected on the previous screen.
Set up the Subnet Mask and Default Gateway.

Confirm the value reflected on the previous screen.

Important:

If the combination of the IP Address, Subnet Mask and Default Gateway is incorrect, Start Setup is inactive and cannot proceed with the settings. Confirm that there is no error in the entry.
Enter the IP address for the primary DNS server.

Confirm the value reflected on the previous screen.

Note:

When you select Auto for the IP address assignment settings, you can select the DNS server settings from Manual or Auto. If you cannot obtain the DNS server address automatically, select Manual and enter the DNS server address. Then, enter the secondary DNS server address directly. If you select Auto, go to step 10.
Enter the IP address for the secondary DNS server.

Confirm the value reflected on the previous screen.
Tap Start Setup.

Setting the Proxy Server

If a proxy server is used for the Internet connection, set up the proxy server in the following situations.

You want to update the printer firmware via the Internet from the printer’s control panel or Web Config.
You want to use Epson Cloud Solution PORT.

Select Menu on the home screen.

When making settings after IP address setting, the Advanced screen is displayed. Go to step 3.
Select General Settings > Network Settings > Advanced.
Select Proxy Server.
Select Use for Proxy Server Settings.
Enter the address for the proxy server by IPv4 or FQDN format.

Confirm the value reflected on the previous screen.
Enter the port number for the proxy server.

Confirm the value reflected on the previous screen.
Tap Start Setup.

Connecting to Ethernet

Connect the printer to the network by using the Ethernet cable, and check the connection.

Connect the printer and hub (LAN switch) by Ethernet cable.
Select Menu on the home screen.
Select General Settings > Network Settings.
Select Connection Check.

The connection diagnosis result is displayed. Confirm the connection is correct.
Tap OK to finish.

When you tap Print Check Report, you can print the diagnosis result. Follow the on-screen instructions to print it.
