OK well I guess I'll try a new print head :).
Here's the line feed image. Any new diagnosis from this?

Looks like any kind of cleaning I did (soaking in windex, rinsing under water) didn't fix the problem (no change in nozzle check). Are there any indications that it may be the printer itself that is defective, before I go buy a new printhead?
Thanks. I ran the check:

I don't get the grid like the pigment black part though. What did you see in the black dye part?
I just got a used ip4300. When I print photos, it looks like there are uneven streaks of brightness. I attached my nozzle check. Does it look right? (other than the pigment black)

The light cyan and light magenta show up, it's just too light to see...
