I hp 4620 officejet all in one printer I replaced all ink and it won't print black. I even took back black ink and got another one. I cleaned the printhead that came out good but no black.

As this is a 4620 I'd advise calling HP phone support, regardless if it's out of warranty, as you may require a replacement
Hope this helps,
