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 a configuration page, see page 134.) 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 Software Installation Guide
.
HP JetDirect 10/100TX print server
If the printer contains an optional 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.
