HP Printer Error Code 01 indicates a firmware download error, meaning your printer attempted to update its internal software but the process failed or was interrupted. This can happen due to a weak internet connection, a corrupted download file, or a temporary glitch in HP's update servers. The good news is that this is a software-level issue and can almost always be resolved at home without any special tools or replacement parts.

Tools You'll Need

How to Fix Error Code 01

  1. Restart the Printer and Router

    Always use the printer's power button to shut it down properly before unplugging. Cutting power abruptly during a firmware update can cause additional errors.

  2. Check Your Internet Connection

  3. Manually Check for Firmware Updates via HP Software

    Do not turn off the printer or computer while a firmware update is in progress. Interrupting the process can corrupt the printer's firmware and cause more serious errors.

  4. Update Firmware Using the HP Website

  5. Disable VPN or Firewall Temporarily

    Only disable your VPN or firewall temporarily and re-enable it as soon as the firmware update is complete to keep your network secure.

  6. Perform a Printer Factory Reset

    A factory reset will erase all saved network settings, custom preferences, and any stored print jobs. Make a note of your Wi-Fi password and any custom settings before proceeding.

When to Call a Professional

If you have completed all six steps and the Error Code 01 still appears, the printer's internal firmware chip or update module may have become corrupted in a way that cannot be fixed through software alone. At this point, contact HP Support directly at hp.com/support or call their technical support line, as your printer may still be under warranty and eligible for a free repair or replacement. You should also contact a professional technician if you notice the printer is completely unresponsive, displays additional error codes alongside 01, or if the firmware update process causes the printer to become stuck in a boot loop.

Frequently Asked Questions

What does HP Printer Error Code 01 mean?
HP Printer Error Code 01 means the printer encountered a firmware download error. This happens when the printer tries to update its internal software but the download fails, is interrupted, or cannot connect to HP's update servers. It is a software issue and does not indicate any physical damage to the printer.
Can I use my HP printer while it shows Error Code 01?
In many cases, you may still be able to print documents while Error Code 01 is displayed, as it relates to a failed firmware update rather than a core mechanical failure. However, it is recommended to resolve the error as soon as possible, since outdated or partially updated firmware can cause performance issues, security vulnerabilities, or additional errors over time.
How do I stop my HP printer from automatically updating its firmware?
You can disable automatic firmware updates through the HP Smart app or the printer's control panel. In the HP Smart app, go to your printer's Advanced Settings and look for 'Printer Updates' or 'Automatic Updates' and toggle it off. On the printer's control panel, navigate to Settings > Printer Maintenance > Update the Printer and select the option to not check for updates automatically. Keep in mind that disabling updates means you will need to install firmware manually to keep the printer secure and functioning properly.
Why does my HP printer keep showing Error Code 01 after I fix it?
If Error Code 01 keeps returning, it is usually caused by an ongoing connectivity issue preventing the printer from successfully completing the firmware download, or by a persistent corrupted file on the printer. Check that your internet connection is stable and consistent, try updating via USB cable instead of wirelessly, and consider performing a factory reset to clear any corrupted cached data before attempting the update again.
Is HP Printer Error Code 01 covered under warranty?
HP's standard warranty covers hardware defects, and if the Error Code 01 is determined to be caused by a hardware failure related to the firmware update system, it may be covered. Contact HP Support at hp.com/support with your printer's serial number to check your warranty status. If your printer is still under warranty and the error cannot be resolved through troubleshooting, HP may offer a repair or replacement at no cost.
