Hello Community, I have a HP Designjet T120 but the printhead alignment keeps failing. I have tried to clean it multiple times using printer built in cleaning features and also manually having it sit on a paper soaked with lukewarm water. Also, the black color on print is very light and is completely missing on the diagnostic image page. The printhead is expensive so I am trying to avoid buying a new one

 

Also, i see black ink leaking inside printhead. Can it be because of clog?
