I primed one of my 3880 cartridges and found the exit channel about half full. It is recommended that it be a least half full, so I figured I would re prime the cartridge.
So I drew more ink out of the cartridge via the exit valve. No visible change, still about half full.
Is there a special procedure I must go through to re prime correctly?
Also, what happens if the exit channel is not quite half and I install and print with your replacement cartridge?
