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. For LaserJet printers or MFPs, does the 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. For internal Jetdirect cards, turn the printer off and back on again. ■ Reinstall the HP Jetdirect print server to ensure it is installed correctly, and verify all connectors are fully mated. ■ If possible, print an HP Jetdirect configuration page and verify all configuration parameters. To interpret HP Jetdirect configuration page messages, see Chapter 9. ■ If your printer contains multiple EIO slots, try using a different slot. ■ Turn off the printer, remove the HP Jetdirect print server, and turn the printer back on. If the error message disappears when the print server is removed, it is likely that the print server was causing the error. Replace the print server. ■ Record all error codes and contact your service provider. If you need to replace the HP Jetdirect print server under warranty service, include all diagnostic and configuration pages with the faulty print server. 2. Does EIOX INITIALIZING/DO NOT POWER OFF 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.
