Hp 5650, black ink not working

I have a wonderful HP Deskjet 5650. I bought a 3rd party HP 56/57 ink cartridges from CompAndSave.com for about $30 for color and black. My color is ok that I still have from HP authentic brand. I have always used HP ink and never a problem; however, HP is very expensive! The copper contacts are clean, the pathway is clean, the printer is clean! The black ink does not come out of the cartridge and the paper is simply blank when coming out of the printer.

When I print in color, the HP color ink is there, but not the black as solid black, or mixed with color for that specific color. I've tried printing in Grayscale=nothing, black=nothing, and color=not correct without the black.

I guess I'll have to pay almost $100 for both color and black from HP again. I have a wonderful HP Deskjet 5650.
