Epson C82324* - Manual (Page 42)

Troubleshooting
Installation
I’m trying to install the Ethernet Card, but after I enter the serial
number, EPSETUP displays an “Unable to locate...serial number...”
message.
Did you enter the correct serial number?
Is the Ethernet Cards host printer turned on?
Is the network cable connected to the Ethernet Card?
I’m installing the Ethernet Card as a remote printer, and EPSETUP
displays a “port number is invalid” message when I enter a printer
port number.
Did you configure the printer port, and assign a queue to the port
using PCONSOLE before entering EPSETUP?
Did you configure the print server port correctly? (See “Before
Running EPSETUP” in Chapter 1.)
Did you reboot the print server after configuring the port and
assigning a queue?
