Hi @Tonycodolo,

Welcome to HP Support Community.  

Thank you for posting your query, I will be glad to help you.

It seems like you're encountering an issue with your HP OfficeJet 6950 printer not accepting the black ink cartridge, and you're receiving a message about Instant Ink compatibility. Here are some steps you can try to resolve the issue.

• Check Cartridge Compatibility: Make sure the black ink cartridge you've installed is compatible with your HP OfficeJet 6950 printer. Verify that it's the correct cartridge model recommended for your printer.
• Reinstall the Cartridge: Turn off your printer and then carefully remove and reinstall the black ink cartridge. Ensure it's securely seated in the correct slot.
• Update Printer Firmware: Check if there are any available firmware updates for your printer. Sometimes, updating the printer's firmware can resolve compatibility issues. You can usually find firmware updates on the HP support website.
• Reset the Printer: Turn off your printer, unplug it from the power source, wait for about 1-2 minutes, and then plug it back in. Turn the printer back on and see if the issue persists.
• Check for Instant Ink Settings: Even if you are not a member of Instant Ink, there might be some settings related to it that need adjustment. Access your printer settings or the HP Smart app to review and disable any Instant Ink-related options.

I hope this helps. 
 

Take care and have a good day.
