Nozzles that do not fire ink when directed are the definition of clogged. The nozzle test print will provide the answer. The only other possible issue could be air bubbles in the k channel.

i would think so to but i put new heads in and as soon as i started printed every color shot perfectly except the K- would the be something in the lines cloggimg the head? which i dont think is the case. I heard it could be a power issue?

kill the power and switch the cables between that and another head - see whick one does it then
