Hey All,

I know this has been asked several times, but I want to make sure I understand before I move on to more drastic measures. I have a HP T730 Printer that is not printing black in. I've removed the printhead, soaked it, and reinstalled and it is not printing black.  BUT.... Black ink does come out when I soak it, and when I dry it on Papertowels, the black lines show along with the red, blue and yellow.

I'm at my wits end, and I really want to make this work.
