Abstract
A fluid delivery system and method, which employs a print head assembly (PHA) and an fluid supply for intermittent connection. A pump structure re-circulates fluid through the re-circulation path during a pump mode. The fluid supply includes a supply reservoir for holding a supply of fluid, and is connectable to the PHA to provide a fluid interconnect between the supply reservoir and the PHA fluid reservoir when a pressure differential between the PHA and the supply reservoir is sufficient to draw fluid into the PHA free fluid reservoir to replenish the fluid in the PHA fluid reservoir.
