Black not printing -lines missing Hp Envy 7640 must clean heads 10 times to resolve.

[P7-1054gman]

HP ENVY 7640 All in One -  Black does not print correctly. Lines missing. This happens every time I use the  printer.  I don't print much.  When I do it pisses me off. Maybe I should just pint in blue. I need to WASTE Ink by cleaning the Heads 10 + times. I have uninstalled and reinstalled software as suggested. I might get to print10 usable and readable pages out of a cartridge of black ink due to excessive head cleaning. This happens with all black cartridges.  I used the printer last week to print 5 or 6 pages and was passable. This is what I get below one week later. Thanks.
