3 For 10/100/1000Base-T print servers, is auto-negotiation properly configured? For EIO print
servers, auto-negotiation may be configured through the EIO Jetdirect menu using the printer's
control panel. Auto-negotiation is the factory default setting.
For proper operation, the link speed and communication mode on the print server must match
the network.
Depending on the print server model, indicator lights are provided to identify the link speed being
used. Verify that either the 10 Mbps, 100 Mbps, or 1000 Mbps link speed light is on. If all link
indicators are off, then a proper link has not been established.
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.
5 Have any software applications been added to the network?
Make sure they are compatible and that they are installed correctly with the correct printer drivers.
6 Are other users able to print?
The problem may be workstation-specific. Check the workstation network drivers, printer drivers,
and redirection (capture in Novell NetWare).
7 If other users are able to print, are they using the same network operating system?
Check your system for proper network operating system setup.
8 Is your protocol enabled on the HP Jetdirect print server?
Check the status of the network protocols on the Jetdirect configuration page. See
Configuration Pages
also use the embedded Web server to check status of other protocols. See
Embedded Web Server
9 Is there an error message in the protocol's section on the Jetdirect configuration page?
