I have two aweful HP 2500c machines that I'm to repair, and I've got all the (minor) problems fixed now, save one: purging the air from several ink lines leading to the printheads.
Ignoring that these printers are not even really worth fixing, how would the air be removed? I've never needed to do this before. Essentially, half of the four flexible printhead lines are just full of air bubbles; the other two seem fine and are solid. Printing, as a result, is very flaky obviously.
Is it just as easy as...sucking on the printhead end of the tubes...really carefully?
Just printing in many pages, in all the colors, doesn't shift the air out for some reason. I have new cartridges installed.
Any tips?
