Connecting the Scanner to the Network
is section explains how to connect the scanner to the network using the scanner's control panel.
Note:
If your scanner and computer are in the same segment, you can also connect using the installer.
❏Setting up from the website
Access the following website, and then enter the product name. Go to Setup, and then start setting up.
http://epson.sn
❏Setting up using the soware disc (only for models that come with a soware disc and users with Windows computers
with disc drives.)
Insert the soware disc into the computer, and then follow the on-screen instructions.
Before Making 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 scanner 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 scanner.
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 scanner connects to.
If MAC address ltering has been set, register the MAC address of the
scanner in advance to register the scanner.
See the following for the supported standards.
“Network Specications” on page 26
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 conguration 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.
Network Settings > Connecting the Scanner to the Network > Before Making Network Connection
13

Divisions Items Note
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 scanner directly accesses to the internet.
For the following functions, the scanner directly connects to the
internet .
❏Epson Connect Services
❏Cloud services of other companies
❏Firmware updating
❏Sending scanned images to SharePoint(WebDAV)
Port number
information
❏Port number to
release
Check the port number used by the scanner and computer, then
release the port that is blocked by a rewall, if necessary.
See the following for the port number used by the scanner.
“Using Port for the Scanner” on page 29
IP Address Assignment
ese are the following types of IP address assignment.
Static IP address:
Assign the predetermined IP address to the scanner (host) manually.
e information to connect to the network (subnet mask, default gateway, DNS server and so on) need to be set
manually.
e IP address does not change even when the device is turned o, so this is useful when you want to manage
devices with an environment where you cannot change the IP address or you want to manage devices using the IP
address. We recommend settings to the scanner, server, etc. that many computers access. Also, when using security
features such as IPsec / IP ltering, assign a xed IP address so that the IP address does not change.
Automatic assignment by using DHCP function (dynamic IP address):
Assign the IP address automatically to the scanner (host) by using the DHCP function of the DHCP server or
router.
e information to connect to the network (subnet mask, default gateway, DNS server and so on) is set
automatically, so you can easily connect the device to the network.
If the device or the router is turned o, or depending on the DHCP server settings, IP address may change when
re-connecting.
We recommend managing devices other than the IP address and communicating with protocols that can follow
the IP address.
Note:
When you use the IP address reservation function of the DHCP, you can assign the same IP address to the devices at any
time.
Network Settings > Connecting the Scanner to the Network > Before Making Network Connection
14

DNS Server and Proxy Server
e 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 scanner performs IP communication.
Queries the DNS server for that information and gets the IP address of the other party. is process is called name
resolution.
erefore, the devices such as computers and scanners can communicate using the IP address.
Name resolution is necessary for the scanner to communicate using the email function or Internet connection
function.
When you use those functions, make the DNS server settings.
When you assign the scanner's IP address by using the DHCP function of the DHCP server or router, it is
automatically set.
e proxy server is placed at the gateway between the network and the Internet, and it communicates to the
computer, scanner, and Internet (opposite server) on behalf of each of them. e opposite server communicates
only to the proxy server. erefore, scanner 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, congure the proxy server on the scanner.
Connecting to the Network from the Control Panel
Connect the scanner to the network by using the scanner's control panel.
Assigning the IP Address
Set up the basic items such as Host Address, Subnet Mask, Default Gateway.
is section explains the procedure for setting a static IP address.
1. Turn on the scanner.
2. Select Settings on the home screen on the scanner's control panel.
3. Select Network Settings > Advanced > TCP/IP.
4. Select Manual for Obtain IP Address.
