Abstract
A fluid jet print cartridge has a cartridge body including a fine-dimension diaphragm portion bounding a printing fluid chamber. This printing fluid chamber is substantially filled with printing fluid, such as ink, by penetrating the fine-dimension diaphragm portion and injecting the printing fluid, while simultaneously using the penetrated diaphragm portion as a barrier to prevent upwelling of printing fluid outwardly of the printing fluid chamber at the penetrated diaphragm.
