Abstract (en)
An ink-jet swath printer employing a cartridge (50) with a spring bag primary reservoir (62) and an auxiliary ink reservoir (230) interconnected via a tube (240) to form a closed ink replenishment system. The primary reservoir creates a negative pressure which draws ink from the auxiliary reservoir as ink is expelled from the cartridge printhead (76) during printing operations. The auxiliary reservoir can either be mounted on the cartridge carriage (210) or on the printer body (202). The auxiliary reservoir is a large capacity collapsible bag mounted below the level of the printhead to establish an ink pressure head at the primary reservoir connection which is not so large as to destroy or diminish the negative pressure and allow ink to drool from the printhead, yet is sufficient to permit replenishment of the primary reservoir to avoid printhead ink starvation.
