I had the SAME issue with my WF-2650 which I purchased less that 1-yr ago.
Even though I had just recently purchased a large quantity of ink for it, I was ready to throw it away.
I patiently ran the nozzle clean time and time again.
After about 15 nozzle cleanings... I prints perfectly.
BTW: I know where you can purchase "CHEEP" ink cartridges for this printer.
They are about 80% less cost than ones purchased at office supply stores.
