It is not uncommon for a refilled HP ink cartridge to register as empty. If it was otherwise filled properly, it should yield the correct number of pages, but you may not be able to get the warning light to go out.
You can try tapping the cartridge on a hard surface. This only works sometimes. Be careful not to splash any ink.
I hope this helps.
