Abstract

See full text

A printhead assembly comprising the printhead and filters intended for use with the printhead is passivated by passing a gaseous coating such as Parylene through the assembly. In this way dirt particles created during manufacture of the printhead are encapsulated and thus prevented from blocking the nozzles. The printhead assembly is also prevented from interacting physically or chemically with ink flowing through the printhead.
