Hi @puckman99,
Welcome to HP Support Community.
Thank you for posting your query, I will be glad to help you.
If the yellow ink sticker on your HP printer cartridge has come off and you're encountering a "Validating, Please wait" message, here’s how you can troubleshoot and resolve the issue:
Steps to Resolve "Validating, Please wait" Error:
Check Cartridge Installation:
- Ensure that the yellow ink cartridge is correctly installed in its designated slot in the printer. Remove it and re-insert it to ensure it’s securely seated.
Inspect Cartridge Contacts:
- Check the electrical contacts on the cartridge and inside the printer where the cartridge makes contact. Make sure there are no visible damages or debris obstructing the connection.
Reset Printer:
- Turn off your printer using the power button.
- Unplug the power cord from the printer and from the power outlet.
- Wait for about 1-2 minutes.
- Plug the power cord back into the printer and then into the power outlet.
- Turn on the printer and check if the error message persists.
Clean Cartridge Contacts (if needed):
- If there’s any dirt or residue on the cartridge contacts, gently clean them with a lint-free cloth lightly moistened with water. Ensure they are completely dry before reinstalling.
Use Genuine HP Cartridges:
- Ensure you are using genuine HP ink cartridges. Non-HP cartridges or refilled cartridges may not work properly and could cause validation issues.
Check for Firmware Updates:
- Visit the HP support website and check if there are any firmware updates available for your printer model. Install any updates as they can include fixes for cartridge recognition and validation issues.
I hope this helps.
Take care and have a good day.
