4880
I got a nearly brand new 4880 printer. Only a few dozen prints ever printed on it. It was idle for indeterminate amount of time. I soaked the printhead with windex for a few minutes, ran a few power cleanings and all of the lines cleared up perfectly, giving a perfect pattern, except for yellow.

Yellow was blank. About six-seven power cleans and a few hundred dollars in ink later, still blank. I checked the yellow ink line and it’s empty.

I disconnect the line from the damper, pull in some ink with a cyringe and it flows. I got it all the way through the line. So, no punctures or clogs in ink line.

So, probably a damper, right? I replaced all dampers. Perfect flow through all, except still no flow of ink through the yellow line during power cleanings. I am all out of ideas. New damper, functional line. What else can it be? What else can i try?

Please help! And thank you so much in advance for any suggestions.
