I replaced all ink cartridges with HP ink, and the black ink won’t print
Product: Example: HP photosmart 6525
Operating System: Mac OS X 10.6 Snow Leopard and older
I replaced all of my ink cartridges with HP ink, and all of them work except the black ink. I’ve cleaned the print heads, and the black doesn’t print. I even bought a new HP black ink cartridge, and the black doesn’t print!!
