Clogged up magenta and yellow

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.


What printer do you have, how old is it?

Did you follow the printer maintenance procedures listed here?

Full channel dying on these printers is rare and is generally indicative of an old printhead.
