Configuring the Internal Print Server / Setting an IP Address for the Printer

Setting an IP Address Using the arp/ping Command

Checking the LAN
Setting and checking the new IP address

If you are using UNIX or OS/2, you need to use the arp command to set the IP address of the Internal Print Server, and the ping command to check that you have set it correctly. You can also use these commands with Windows Me/98/95/XP/2000/NT, if you have correctly installed TCP/IP networking on these systems.

Note:

Make sure that the Set by PING function is enabled on the TCP/IP menu in EpsonNet WinAssist or EpsonNet WebAssist. If this function is disabled, you cannot set the IP address using the arp/ping command.

Before you start, you need the following information:

A valid IP address for the Internal Print Server. Ask your system administrator for an IP address which does not cause conflicts with any other device on the network. If you are the system administrator, choose an address within your subnet which does not conflict with any other device.

The MAC (Ethernet hardware) address of the Internal Print Server. You can find out the MAC address on a network status sheet.

Checking the LAN

First, you need to check that the Internal Print Server can be reached from the host, as follows:

Set the default gateway to the host on which you are setting up the Internal Print Server.

If there is a server or a router which acts as a gateway, enter the address of the server or the router. If there is no gateway, enter the IP address of your computer as a gateway address.

The default IP address of the Internal Print Server is "192.168.192.168". Check that the Internal Print Server is reachable by "pinging" it from the command line:
ping 192.168.192.168

If the Internal Print Server is reachable, you can see the following result (the exact form of the message depends on your operating system, and the time may vary):
64 bytes from 192:168:192:168:icmp_seq=0. Time=34.ms

If the Internal Print Server is unreachable, you may see something like this:
PING 192:168:192:168:56 data bytes

If you press Ctrl-C, you may see something like this:
192:168:192:168 PING Statistics
3 packets transmitted, 0 packets received,
100% packet loss

Again, the exact wording of the message you see may differ from this, depending on your operating system. If you cannot "ping" the Internal Print Server, check the following:

The address in the ping command is correct.

The Ethernet connection to the Internal Print Server and to the host has been made correctly, and all hubs, routers, etc. are switched on.

The Internal Print Server is operating normally (red light off, green or orange light on).

Setting and checking the new IP address

To set the new IP address which you have obtained from your system administrator, use the arp command with the -s flag (create an ARP entry).

Note:

In the following procedure, we assume that the MAC address of your Internal Print Server is 00:00:48:93:00:00 (hexadecimal), and that the IP address which you will be assigning is 192.168.100.201 (decimal). Substitute your values for these addresses when you type in the commands.

From the command line, type:
Example: arp -s 192.168.100.201 00-00-48-93-00-00

You can now check the new IP address, by "pinging" it:
Example: ping 192.168.100.201

The Internal Print Server should now respond to the ping. If it does not, you may have incorrectly typed the MAC address or the IP address in the arp -s command. Double-check and try again. If none of these actions are effective, re-initialize the Internal Print Server and try again.

Print a network status sheet to check whether the new IP address has been assigned to the Internal Print Server.

Note:

When you set the IP address of the Internal Print Server in this way, you cannot change the subnet mask or the gateway setting of the Internal Print Server. You must use EpsonNet WinAssist on Windows (Me, 98, 95, 2000, or NT), EpsonNet MacAssist in Macintosh, or EpsonNet WebAssist to change these parameters.
