Abstract
An ink-jet print cartridge is formed by a rigid outer protective case and an inner ink reservoir having a flexible wall portion and a rigid wall portion which together form a sealed compartment. The flexible wall portion includes two opposing membranes sealed at their periphery to an inner loop-like frame which is integrated with a portion of the outer case. The outer protective case also covers a snout having a shortened length in the media advance direction to allow media positioning rollers closely adjacent to the print zone. The snout includes internal filters in an ink passageway from the reservoir to print nozzles at the end of the snout.
