all was going fine, and then poof, magenta and yellow are not flowing. did cleaning, did 3 power cleans, still they are clogged. I put a syringe in the cartridge and ink came out easily. I looked inside the printer, and from what I could see, the lines didn't have any obvious bubbles. This is driving me INSANE. before when it happened, power clean cleaned it.
BTW,-4 power cleans and a dozen prints filled the maintaince tank. another drag.
