I've had trouble with my 1204 for several weeks now. It would not print yellow at all!!! After researching talking with others in the industry, I purchased and changed all the dampers as well as the maintenance station. I used a syringe to pull inks into the new dampers and have run "little charge" cleaning numerous times. My problem now is it will not print a single drop of any ink after what seems like 100 attempts at printing a rather large test print. Any suggestions on what to try next would be appreciated!
