Prerequisites

1. NOTE: This article assumes the network card in the printer is model E04. If you are unsure of of what network module you have, each card should have a tag that either says E04 or E03 (see image below under instructions). If you need the instructions for the E03 model, Click Here.

2. This article pertains to Epson Models:
        TM-U220B - Ethernet
3. The printer will need to be plugged directly into a windows PC or on the same physical network.
4. The article assumes that the printer is reset to factory default IP of 192.168.192.168

Instructions

1) To verify that the printer's network information is set to the factory faults (IP 192.168.192.168), press and hold the reset button located near the Ethernet port (see image below).  When the printer starts to print the information sheet release the reset button.

    If the IP Address is not 192.168.192.168, and it is necessary to reset to factory defaults do the following:
    For Model TM-U220 Printer:
        Turn the power to the printer OFF.  Note: The power switch cover will likely be on so you may need a pin or paper clip to access the power switch.
        Press and hold the reset button located near the ether net port
        While still holding the reset button, turn the power to the printer ON.
        When you hear the printer start to print the messages saying factory reset in process, Release the reset button.  DO NOT turn off power to the printer while the reset is occurring.
        The printer will then print a message saying that the reset is complete.

2)  On a Windows PC, with the printer directly connected via Ethernet cable OR on connected on the same physical LAN, Go to Control Panel, Network and Internet, Network Connections.  Note: On Windows 7, click on Network and Sharing Center, Change Adapter Settings

3) Right Click on the appropriate Local Area Connection and Select Properties (see image below)

4) Select Internet Protocol Version 4 (TCP/IPv4) and click the Properties Button (see image below)

5) Click the radio Button for Use the following IP address and type the following network information (see image below):

    IP Address: 192.168.192.160
        Note: by setting an IP that is on the same address structure as the printer, the PC and printer will be able to communicate.  If the printer is not reset to the factory default then just set the PC on an address that is the same to the left as the last decimal, but different to the right. (SSS.SSS.SSS.DDD)
    Subnet Mask: 255.255.255.0
    Default Gateway: This is only required if not connected directly or on the same physical LAN.

6) Push the OK button then hit the Close button on the previous screen to commit the network changes.

7) Open up a web browser.  Note: To make sure the browser is using the current network settings, close any previous browser sessions first.

8) Type the IP address of the printer (192.168.192.168 if set to factory defaults) into the address bar of the browser.

9) The browser will prompt to enter in the username and password for the printer (see image below). Unless someone has changed this, the username and password are as follows:

• UN: epson
• PW: [serial number of printer]

10) Press Ok. This should open up the web configuration utility for the printer.  If is does not, troubleshoot the prior steps.

11) Under Configuration Heading on the left side of the page, Click TCP/IP

11) To set a printer up statically (recommended), the settings should be as follows:

•     Get IP Address: Manual
•      Note: If wanting printer to get address via DHCP, this setting would be set to Auto (not recommended as permanent setting as this could change and printing would not work)
•     IP Address: [Insert IP address provided by the community]
•     Subnet Mask: [Insert Subnet Mask provided by the community]
•     Default Gateway: [Insert Gateway provided by the community] Note: typically the printer will work if a gateway is not provided assuming they are on the same physical network, but best practice is to input the value.
•     Set using Automatic Private IP Addressing: Disable
•     Set using ARP+PING: Disable

12)  Press the Send Button.

13)  Press the Reset Button and after a few seconds the printer will be reset with the new network settings (see image below).

14) To put the Windows PC back on its normal network configuration, follow steps 2-6, but choose Obtain an IP address automatically.
