You might be able to resurrect the head by squirting windex into the pads and into the bottom head jets. I don't know if I would soak it under liquid because there's micro-circuitry just under the plastic shield surrounding the jets. Try then running the clean cycles again, If it still does not work then the head probably has a screwed up micro-circuit.
I had one of my i850's start doing this and never could get those lines to go away. I finally bought a new head and now it's like a new printer all over again.
Nowadays, it's not worth buying a new head unless you can find one on eBay for cheap.
