hi! Iwas wonderin about this one

Let say if I run out of only yelow in my printer and then swap cartidge for new one. you can see printer charging the ink (or cleaning the heads?) is this doing for all the cardridges or only that new one i just put in?

also whats the diferent between "ink chargin" vs. "head clean"?? I mean I know whats the diferents but i dont know how diferent process is. I always thought head clean is made by forcing ik trough the heads. (same as charging??)

any one can explain as iam
