|Seems strange to contact HP - you wouldn't expect them to support you using refilled cartidges - quite the reverse. All printer manufacturers expect you to use their own replacements.|
Cartridges commonly incorporate chips for ink level detection. As it says "incompatible" maybe they have updated their software to block cartridges after the ink has reach minimum level once.
Ink quality can vary from unknown sources but I doubt it would ever be bad enough to damage the printer.
Always pop back and let us know the outcome - thanks
