Method of priming pagewidth printhead

Abstract

A method of priming ejection nozzles of a printhead is provided in which inwardly directed force is applied on an exterior wall of a bag containing fluid for distribution to the nozzles so as to reduce an available fluid volume of the bag, thereby causing fluid to be distributed from the bag to the nozzles, and a biasing member in the bag is caused to apply outwardly directed force on an interior wall of the bag so as to restrain the reduction of available fluid volume of the bag only once the available fluid volume of the bag has been reduced to a predetermined volume. The printhead is a pagewidth printhead having a pagewidth of greater than 100 millimetres.
