HP 640n Print Server manual Procedure 3 Resolve printer display error messages

If the configuration page does not print, check the following items:

1.Did you perform the correct steps on the printer to print the configuration page?

The steps to print a configuration page vary between different printers and print servers. (See the documentation supplied with your print server.) The following are general instructions.

For EIO and embedded print servers, an HP Jetdirect page typically prints along with the printer configuration page. Use the printer control panel menus.

For external print servers, press the Test button on the print server.

2.Is there a print job in process?

You cannot print an HP Jetdirect configuration page to the printer while a print job is in process. Wait until the print job is complete, then print the configuration page.

3.Does an error message appear on the printer control panel display?

●See Procedure 3 in this section for a list of network-related error messages and corrective actions.

●See your printer documentation for a complete list of control panel messages and corrective actions.

Procedure 3: Resolve printer display error messages

To resolve network-related error messages that appear on the printer control panel display, use the following steps: This information assumes you have already printed a configuration page.

1.For LaserJet printers or MFPs, are there Service Error messages, such as 49.XXXX, 79.XXXX or 8X.XXXX?

●See your printer manuals to interpret the error message.

●If you recently upgraded the HP Jetdirect firmware, turn the print server off and then on. For EIO and embedded HP Jetdirect print servers, turn the printer off and then on.

●Verify all connectors are fully mated.

●Print an HP Jetdirect configuration page and verify all configuration parameters. To interpret the configuration page messages, see HP Jetdirect configuration pages on page 139.

●Disable the embedded HP Jetdirect print server operation, using the Service menu. If the error message disappears when the print server is disabled, it is likely that the print server or network is causing the error. Contact your service provider.

●Record all error codes and contact your service provider. If warranty service is required, include all diagnostic and configuration pages.

2.Does EIOX INITIALIZING/DO NOT POWER OFF appear on the display?

Wait for ten minutes to see if it clears. If not, you might need to contact your service provider.

3.Does a 49 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.
