Hi, I'm Nathan.Sorry to hear that you're having trouble with this but I'll do my best to help you.
What is the complete model number of the printer?Are you certain it isn't showing that another cartridge (one of the color ones) isn't low also?
That does mean that a cartridge is empty, those drops are for the ink.
Are you using genuine HP ink, or generic/refilled cartridges?
Hello, it appears your question is still open.
Do you need more help with this?
