MFC-J6545dw - yellow ink shows black on print quality test

[nonalea]

I changed the ink cartridge after discovering that yellow is printing black on both my prints and on the print quality test sheet. The printer screen shows that it recognizes that there is a full yellow ink cartridge. I have done a nozzle cleaning several times and the quality test sheet continues to show really nice black bars in the yellow space.

not sure what I need to do next???

I have the same, I have a MFC-j6930DW, got it second hand few days ago. I ran deep cleaning several times, it than got a little better. But now that I have changed cartridges it is getting worse again... It also looks like there is air in the hoses to the printhead, could that cause this? I hope someone can answer how to solve this. (btw, I changed printer language between those two sheets in the image)
