Review on HP 901 Black Ink Cartridge for HP OfficeJet 4500, J4500 series, J4680 (CC653AN) by Jason Unruh

I bought this product last year to print for college. After replacing the old cartridge, this page didn't print, or if I had it set to Best Print, it might have printed very light grey. I didn't think much about it at the time because I didn't have much time and found other ways to print what I needed without my printer. I recently tested it and the HP Solution Center app on my computer says the ink cartridge is full, but it still doesn't print black like it used to. Prior to this purchase I bought a color and black duo and it worked well.
