Hi All,

I am trying to refill a hp printhead but there is an air bag inside the cartridge which I can inflate or deflate, I am thinking that maybe I should inflate it before filling then reseal the cartridge and deflate to cause some back pressure to stop nozzle leakage. Does anyone know the answer on how to do this?

Regards
