Procedure 4: Resolving Printer Communication Problems with the Network

Check the following items to verify that the printer is communicating with the network. This information assumes you have already printed a Jetdirect configuration page.

1.Are there any physical connection problems between the workstation or file server and the HP Jetdirect print server?

Verify network cabling, connections, and router configurations. Verify that network cable lengths meet network specifications.

2.Are your network cables connected properly?

Ensure the network cable connectors are properly connected. If the problem continues, try a different cable or a different network port on the hub or switch.

3.For 10/100Base-TX configurations, is autonegotiation properly configured?

The speed and communication mode on the print server must match the network for proper operation. Autonegotiation for the print server may be configured from the printer’s control panel.

If the print server’s RJ-45 network	100 Mbps

4.Is the print server connected to an

802.1X network and properly configured for EAP/802.1X operation?

The network must support the Extensible Authentication Protocol (EAP) method configured for use on the print server.

Verify the configuration of the network’s 802.1X port. If it does not allow guest or temporary access, you may need to preconfigure the Jetdirect print server for 802.1X operation before connection to your network. This is done using an isolated LAN, or through a direct computer-to-printer connection using a cross-over cable.
