Hi @Mb-5,

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 6978 printer has activated the "HP Cartridge Protection" feature, which can prevent non-HP ink cartridges from being used. Here’s how you can try to resolve the issue.

Steps to Disable HP Cartridge Protection:

From the Printer Control Panel:

• Tap on the printer’s Control Panel.
• Go to Setup > Tools > Preferences > Cartridge Protection.
• Select Disable Cartridge Protection.

Via HP Smart App or HP Printer Software:

• Open the HP Smart app or the HP Printer Software on your computer.
• Select Printer Settings or Printer Toolbox.
• Look for HP Cartridge Protection and disable it.

From the Embedded Web Server (EWS):

• Ensure your printer is connected to the same network as your computer.
• Get the printer’s IP address from the control panel: Settings > Network > Network Settings > Wireless Settings.
• Enter the printer's IP address into a web browser to open the Embedded Web Server.
• Navigate to the Settings or HP Cartridge Protection tab.
• Disable the Cartridge Protection feature.

I hope this helps.

Take care and have a good day.
