Troubleshooting the HP Jetdirect Print Server 170

Procedure 3: Resolving Printer Display 
Error Messages

Check the following information to resolve network-related error 
messages that appear on the printer control panel display. This 
information assumes you have already printed a configuration page.

1. Does the printer’s control panel display a Service Error message, 

such as 49.XXXX, 79.XXXX or 8X.XXXX error?

■ Refer to your printer manuals to interpret the error message.
■ If you upgraded the Jetdirect firmware recently, power the 

print server off/on using the printer’s On/Off switch. 

■ Verify the network cable is properly connected.
■ Inspect and verify the configuration parameters on the 

Jetdirect configuration page. To interpret HP Jetdirect 
configuration page messages, see Chapter 9.

■ Record all error codes and contact your service provider. For 

warranty service, include all diagnostic and configuration 
pages with the faulty print server.

2. Does INITIALIZING/DO NOT POWER OFF or similar message appear 

on the display?

Wait for ten minutes to see if it clears. If it does not, you may 
need to replace the HP Jetdirect print server.

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.
