I have been using non HP cartridges on my HP 8022e printer without any problem until now.

I have been using non HP cartridges. It has worked fine. In fact, I have a black one in now and it has worked fine. But now I installed a red one and all of the sudden, it comes up with Non hp chip detected. The cartridges have been blocked by printer firmware. I need to go back to older firmware, Where is firrmware for 8022e? And which edition do I need to backup before HP added this chip detector.

Hi @D_Family,

Welcome to the HP Support Community. 

I'd like to help!

Most recent hp printers do not allow firmware downgrade. They have built-in code that checks the version of the download and will not accept any firmware that is earlier than the current version. 

Are you able to copy documents?

How is the printer connected, USB or Wireless?

Any error when you try to print?

Power resetting the printer and then performing an automated/manual cleaning may resolve the issue. Let's try these steps:

1) Make sure this printer is plugged into a direct wall, not a surge protector

2) Remove all of your ink cartridges from the printer and close the door

3) Remove the power cord from the back of the printer (Do not press the power button)

4) Clean the ink cartridges, click here

5) Plug the power cord back into the printer

6) Wait for the printer to turn on completely, then install the ink cartridges.

7) On the printer control panel, swipe the display to scroll to Setup, and then touch the Setup icon (). The Setup menu displays.

Swipe the display to scroll to Tools, and then touch Tools.

9) Touch Clean Printhead, and then touch Continue. When prompted touch Clean Again or OK to continue the next level of cleaning. Repeat these steps for the third cleaning stage.

Let me know how it goes!
