HP Smart Tank 651
macOS 12.0 Monterey

My printer won't print black, but colors are fine. I've filled the ink tank and ran the "clean cartridges", "align cartridges", and "clean smudges" diagnostic tools. Looking at the support site and other community posts, it looks like the problem lies with the printhead. 

 

So, I thought I'd take a look at the printhead, see if maybe there's dried ink or some other glaring issue – last diagnostic step before ordering a new printhead. I followed the instructions on this page https://support.hp.com/us-en/document/c06263927, but the printhead doesn't move to the center, and according to the page, this means the printhead doesn't need to be replaced? So.. I'm at a loss. 

 

Can someone advise please? Thanks so much.

Any ideas on this one? It seems like it should be a relatively simple fix, but as it stands, my printer is a brick. Would appreciate any insight - thanks.
