My printer had the same problem - when printing a typical Word document page, it would put some black ink on paper, but only some lines would print, leaving most of the page blank.
I tried to realign the heads several times, it did not fix the problem. I changed the black ink cartridge, it did not help either.
So I went on Amazon, ordered new "hp original" printing heads, got them delivered from a third party vendor in a couple of days, changed the heads, and now my printer works as new.
Changing the heads costs me 1/3 of the price of a new printer. The local electronics company who sold be the printer did not have heads on stock and was only willing to sell me a new printer.

I have a HP Photosmart 6520 eAll in One printer. After changing print cartridges my printer will not print in black. I am out of warranty so probably going to have to replace.
I see that one suggestion is to manually clean but have no idea how, any help appreciated.
