Procedure 4: Resolving Printer Communication Problems With The Network - HP 635n - JetDirect IPv6/IPsec Print Server Administrator's Manual

3 Does a 40 ERROR appear on the printer's control panel display?
The HP Jetdirect print server detected a break in the data communications. When this error
occurs, the printer goes offline.
A break in communications may result from the physical network connection being disrupted or
the server going down. If your printer has an Auto Continue feature that is disabled or off, you
must press the appropriate key (Start or Pause/Resume, for example) on the printer after the
communications problem is solved to put the printer back online. Turning the Auto Continue
feature on forces the printer to reconnect without user intervention. However, this does not solve
the disconnect problem.
4 Does an initializing (INIT) message appear on the display?
This is a normal message. Wait about 3 minutes for the message to clear, or another message to
appear. If another message appears, see the printer's documentation and configuration pages
for additional information.
5 Does a message other than READY or the messages listed in this section appear on the display?
See your printer documentation for a complete list of control panel messages and corrective
actions.
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?
Make sure that the printer is attached to the network using the appropriate HP Jetdirect print
server port and cable. Check each cable connection to make sure it is secure and in the right
place. If the problem continues, try a different cable or network port on the hub or switch.
