I am struck that thousands have looked at this page about a very basic problem—not being able to print black!—and the ONLY response from HP is a robotic message to do what we've all been spending hours doing according to instructions. Their only advice is to send it in for repair, when I'm sure that would cost more than buying a new printer. Incredible. I have to throw away the ink that, like so many others, I purchased to try to fix this problem. But this is as bad as company support gets.
See ya. I'm off to buy an Epson, or anything besides HP. This is the third HP printer I've had problems with over the years.

I have an HP Photosmart 6520, and the black ink is not working. I have cleaned the ink cartridge, cleaned the printheads, realigned the printer, and cleared the cartridge vent. I have no idea what to do next. Any suggestions before I give up and just get a new printer?

RePosting again a sort of hack tutorial i used to fix the same problem with my Officejet pro 6830.
This is not exactly a final solution bc the black ink process may fail again, but i can assure once i‘ve repeated the steps below, the black ink printing process always worked here o.O
1 - disconnet the power cable
2 - reconnect the power cable and connect an usb/ethernet cable to your PC.
3 - turn on the machine, and remove the black ink cartridge
4 - get an old cartridge used before (not the last one in use with the print problem) and install it.
5 - wait for the messaging “black ink cartridge used before whatever” and remove the old one from printer
6 - reinstall the new black ink cartridge(or the latest in use) and try to print test pages/docs again
