The printer settings or network settings may be wrong.

First, check to see if you can print a status sheet, as described in Printing a Network Status Sheet. If you can print a status sheet, check the network settings; otherwise, set the interface mode of the printer’s control panel to Auto or Option.

You have assigned an IP address to the computer manually, but you assigned the IP address to the printer by Automatic Private IP Addressing (APIPA).

Assign the printer’s IP address so that it belongs to the same segment of the computer. Use EpsonNet Config and the printer’s control panel.

You have added or deleted protocols after installing EpsonNet Config.

Uninstall EpsonNet Config and then reinstall it. See Uninstalling Software and Installing EpsonNet Config.

Both TCP/IP and IPX/SPX are not installed on the computer.

Install the TCP/IP or IPX/SPX protocol.

TCP/IP is installed on the computer, but its IP address is not set correctly.

Set a correct IP address for the computer.

This may happen when using a dial-up router.

Run Command Prompt from the computer on which EpsonNet Config is installed, and then enter the following command:

Format: >ROUTE_ADD_the IP address of the network interface_ the IP address of the computer (the under bar represents one space)

Example: >ROUTE ADD 192.168.192.168 22.33.44.55.

You have not set the IP address for the network interface.

Set the IP address for the network interface using EpsonNet Config for Windows or Macintosh, the printer’s control panel, or the arp/ping commands. You can check the IP address on a status sheet. See the EpsonNet Config User’s Guide or Setting an IP Address Using the arp/ping Command.

The network interface is not connected to the network.

Connect the network interface to the network, and check the network environment.

The printer is located beyond the router.

The printer and the computer must be in the same segment.

If the valid IP address is not set, the items indicated in the dialog box mentioned above may not appear.

Set a valid IP address.

Refresh the status by selecting Refresh from the View menu.

Increase the length of time before a timeout. To do this, select Options from the Tool menu, and then select Timeout. Note that doing so can cause EpsonNet Config to run more slowly.

NetWare is set to Enable even though you are not using NetWare.

Set NetWare to Disable on the NetWare screen of EpsonNet Config with Web Browser.

How to acquire an IP address.
To acquire your IP address, you need to apply to the NIC (Network Information Center) in your country.
