Event Code: 71.02.4A

[GregC421]

I've tried unplugging the unit, downloading updated firmware and resetting printer setting to factory. Nothing clears this error code. Is this unit shot for good? I have an Office Jet Pro 8020.

Hi @GregC421,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

The error code 71.02.4A on your HP OfficeJet Pro 8020 isn't a widely recognized or standard error code, which might be why you're having difficulty resolving it. Generally, error codes that aren't easily identifiable suggest a more obscure issue, possibly at a hardware level, which might not be easily resolved through standard troubleshooting steps like the ones you've already tried (unplugging the unit, updating firmware, resetting printer settings).

Here are a few additional steps you can take to try and resolve the error:

Detailed Power Reset:

• Turn off the printer and unplug it from the power outlet.
• Wait for about 1-2 minutes.
• Press and hold the power button for about 30 seconds while the printer is still unplugged. This can help discharge any residual power in the printer, which can sometimes clear unseen errors.
• Plug the printer back in and turn it on to see if the error persists.

Check for Obstructions:

• Open up the printer and check for any paper jams or debris that might be causing an issue. Even small pieces of paper or accumulated dust can sometimes cause errors.
• Check the ink cartridge carriage to ensure it moves smoothly. If it’s stuck, try gently moving it to see if there’s anything obstructing its path.

Reinstall Ink Cartridges:

• Remove the ink cartridges and reinstall them to ensure they are properly seated and there are no connectivity issues that might be causing the error.

Check Warranty and Service Options:

• Verify if your printer is still under warranty. You might be eligible for a free repair or replacement depending on the terms of the warranty.

I hope this helps.

Take care and have a good day.
