"Non-HP Chip Detected" 

Hi. This is a working instruction to help people who are faced with these error messages:

Some HP printers may show error messages after automatic firmware updates.

These updates can sometimes cause compatible cartridges to stop working — even though nothing is wrong with the cartridges themselves.

If you’d like to keep using your compatible cartridges, a firmware downgrade can help fix this issue.
This is safe for your printer.
You’re simply installing an earlier official HP firmware version, with no changes to features or print quality. 

Make sure to follow the final step in the instructions to turn off updates through the printer display to avoid this problem in the future.

Before you start, please note:

• These instructions are for Windows computers only (not Mac).
• Make sure your printer is connected to your computer (via Wi-Fi or USB cable).

1. Select your printer from the list below and download your fix:

*. The file is safe to use and will not harm your computer. It's previous version (1847AR) of original HP firmware for the printers from 2019 (not modified).
*No difference in perfomance, features or security - old version just does not block non-original cartridges.

2. Click on the downloaded zip archive: 

9. Your printer may run a short maintenance process. This is normal and usually takes about 2–3 minutes — just wait until it finishes.

*If you see an error message stating "Used or counterfeit, the contents of the original HP cartridges have been depleted. If they were sold to you as new," that's ok.
The ink levels may not be displayed, but the cartridges should still function properly.
