Abstract:
An ink jet printing system for forming images on print media, the ink jet printing system comprising:a printhead configured for mounting in a scanning carriage for ejecting ink onto print media in response to print signals; an ink container spaced from the printhead for storing ink; a fitment structure attached to the ink container, said fitment structure including a fluid interconnect, said fitment structure having a fluid path for passing ink therethrough between the fluid interconnect and the ink container; an ink conduit connected between the printhead and the fluid interconnect for providing ink from the ink container to the printhead, said fluid interconnect adapted for detachable connection to the ink conduit; and a fine mesh structure disposed in the fluid path such that ink passing into the ink conduit from the ink container passes through the mesh structure, the fine mesh structure having a mesh opening size which is sufficiently small to prevent air bubbles from passing through the fluid outlet under nominal air bubble pressure experienced by the ink jet printing system in usage and storage.
