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. q Check the HP JetDirect configuration page (to print, see "Configuration page" on page 152). q 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: q 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. q 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 manually set the link speed (10 or 100 Mbps) and duplex mode (full- or half-duplex) so that they match the network (see "EIO Menu" on page 225). 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 off and back on and check the print server operation. If the print server fails to link, try a different network cable. 150 Chapter 4 - Problem solving EN
