My printer is making lines in the color and we just bought new ink!?

Q: Im trying to print party invitations that are pink and black, but there are lines in them where the color is lighter than it should be so they looked striped. We just bought new ink so I dont see what's wrong. How do I get rid of it? What's wrong with my printer? its an HP Photosmart 7660 I used clean the cartidge and the page i printed says that if there are streaks on the page it has printed then i may need to replace the ink cartridge (again!) or clean it. (isnt that what im doing?) Ok last one, the cleaning seems to have worked! Thanks guys!

A: you should have a clean the head options. try it before you take it back
