• Code: 8X.XXXX
• Display: 8X.YYYY EIO ERROR
• Description: The EIO accessory card has encountered a critical error.
• Remedy: 1. Turn the device off and then on. 2. Upgrade the Jetdirect firmware. 3. Try to determine whether the error occurs intermittently, while printing, or when turning on the device. 4. If the error appears while printing, determine whether it occurs when printing from a specific computer, a specific application, or a specific file. If all other computers, applications, or files can print without the error, then the problem may be only within one print job or computer. Make sure the computer has the most current printer drivers, or use a generic printer driver. 5. If the error occurs when the device is first turned on, turn off the device, disconnect the LAN cable, and then turn on the device. This process will determine if errors occur from the network connection. If errors do not appear when the LAN cable is unplugged, it is possible traffic or signal on the network might be causing the error. Make sure to try all solutions suggested, especially upgrading the Jetdirect firmware. 6. Disable the print server. ?? For EIO print servers, remove the card. ?? For embedded print servers, use the SERVICE menu. 7. If the problem persists, contact HP Support.
