Abstract
The invention is directed to a method and apparatus utilizing a capping element having a sealing element or gasket which is pushed against the orifice plate of an acoustic ink printhead when capping and filling. This traps a small volume of air around an array of orifices in the orifice plate which prevents ink from exiting the orifices while the printhead is being filled with ink.
