I have a photosmart 6520 which the black ink stopped working. I have windows 10 not sure if it is 32 or 64 bit. I tried all the suggestions from the HP website and none of them fixed the problem, Any suggestions greatly appreciated since I just replaced all four cartridges . Thanks!

Since you have tried everything on the HP web site, try these Youtube videos here.
Search for more if needed. If no joy your printer is toast.
