Review on 🖨 HP 901 ink cartridges for OfficeJet 4500, J4500, J4680 | CZ075FN Black Ink by Adam Ross

This got one star because it wasn't possible to get zero stars. I bought this pack of two cartridges in February - I probably put the first cartridge in my printer a few weeks later. I don't type much; Typically the ink will last a year or more. But this one ended last week. So I put in a second pack and my printer said my ink was full. But he didn't print anything in black; the only thing he printed was color. I took it out and made sure the tape was completely removed; put returned again and tried to print a test page. The only thing he printed was color. I've run diagnostics and tried taking it out again and again, cleaning the printheads and trying everything I could think of. The ink cartridge is defective.
