Communicating with an optional HP Jetdirect print server
If the printer contains an optional HP Jetdirect print server, and you cannot communicate with
the printer over the network, verify the operation of the print server.

Check the HP Jetdirect configuration page. To print one, see “Configuration page” on
page 83 .

If the message "I/O Card Ready” does not appear on the HP Jetdirect configuration page,
see the troubleshooting section of the
HP Jetdirect Print Server Administrator’s Guide .
If the printer contains an HP Jetdirect 10/100TX print server, check to see that the print server
was able to link to the network:

Check the link-speed indicators (10 or 100) on the print server. If both are off, the print server
failed to link to the network.

Check the HP Jetdirect configuration page. The message “Loss of Carrier Error” indicates
that the print server failed to link to the network.
If the print server failed to link, verify that all cables are correctly connected. If all cables are
correctly connected and the print server still fails to link, follow the steps below to reconfigure the
print server:
1 Use the EIO menu to set the link speed (10 or 100 Mbps) and duplex mode (full- or half-
duplex) so that they match the network. (See
“EIO [X]” on page 165 .) For example, if the port
on the network switch is set for 100TX full-duplex operation, you must set the print server for
100TX full-duplex operation.
2 Turn the printer power off and back on and check the print server operation. If the print
server fails to link, try a different network cable.
