Hi @Marc196, Welcome to HP Support Community.
Thank you for posting your query, I will be glad to help you.
It sounds like your HP OfficeJet Pro 9012e is stuck in a firmware loop while validating the new cartridges. Try the following steps to resolve the issue:
Perform a Power Reset
- Turn off the printer and unplug the power cord from both the printer and the wall outlet.
- Wait for at least 2–3 minutes to allow the internal memory to reset.
- Press and hold the power button for 15 seconds to discharge any residual power.
- Plug the power cord directly into the wall outlet (not a surge protector) and reconnect it to the printer.
- Turn the printer back on and check if it passes the validation process.
Remove and Reinsert the Ink Cartridges
- With the printer turned on, open the cartridge access door.
- Remove all ink cartridges and close the door.
- Wait for 30 seconds, then reopen the door and firmly reinsert the cartridges.
- Close the door and see if the printer resumes normal operation.
Use Original HP Setup Cartridges
- If this is the first-time setup, ensure you are using the original SETUP cartridges that came with the printer.
- If the printer is already activated, use genuine HP cartridges.
Check for a Firmware Update (If the Printer Starts Working)
If you manage to get past the validation screen:
- Open HP Smart or go to the HP Support website to check for a firmware update.
- Install the latest firmware to prevent future cartridge validation issues.
I hope this helps.
Take care and have a good day.
