Troubleshooting
The IP addresses aren't working correctly on all the computers.
Possible cause
The IP addresses you set
are conflicting or incorrect.
The IP addresses don't
work correctly on occasion
and you are on a network
that is connected directly to
the Internet.
Pinging the card gives you no results (UNIX or Windows 95).
Possible cause
You typed the wrong
address in the ping
command.
The hardware is not
connected correctly.
The IP addresses are not
working correctly.
Your computer can't communicate with the Ethernet card.
Possible cause
The card is on a different
segment of the network,
and the gateway or subnet
mask is set up incorrectly.
You may have a hardware
problem.
Solution
Check all the computers carefully to make sure they have different
IP addresses and that they all have the same network ID (the first
part of the IP address). Also make sure they have the correct
subnet masks and are set up to use the correct gateway (if used).
If you are directly connected to the Internet (not by a dial-up
connection), be sure to obtain a range of IP addresses from the
InterNIC. Otherwise, you may have conflicts with other computers
on the Internet. If you don't have legitimate IP addresses, either
disable TCP/IP or disable your connection to the Internet, and get
the addresses from the InterNIC.
Solution
Check and retype the command correctly.
Check all the cables and make sure the printer and the Ethernet
card are turned on and working correctly. If you have 10BASE2
cable (thin coaxial), make sure it is terminated correctly.
Check the previous table for solutions.
Solution
Check all the settings of the gateway and the subnet masks. When
you are using EPSON Net!, you must use a computer that is on the
same segment of the network as the printer to configure its
Ethernet card.
Make sure all the following are turned on, connected, terminated
(if necessary), and working correctly:
Your computer
Printer
Print server
Server
Ethernet card
Routers
Hubs
All other equipment on the network between your computer and
the printer
