    摘要: A fluid delivery system of the invention comprises one or more intercoupled cartridge assembles. Each cartridge assembly comprises a plurality of interconnected cartridges, each comprising a reservoir for holding jetting fluid and an ink jet print head operatively connected to the reservoir. Each cartridge assembly is interconnected by a first interconnection assembly and a second interconnection assembly. The first interconnection assembly maintains the plurality of interconnected cartridges at a negative pressure. The second interconnection assembly maintains at least an essentially equal level of jetting fluid within each of the reservoirs of the plurality of cartridges. Jetting fluid is replenished in the plurality of interconnected cartridges by replenishing jetting fluid in a selected cartridge and using the second interconnection assembly to distribute the jetting fluid among the reservoirs of the interconnected cartridges. A sensor is coupled to the selected reservoir to monitor the level of jetting fluid in the cartridge assembly.

    摘要: A mounting slider bracket for a card printer thermal printhead is supported between a spring and the printhead, and can be adjusted laterally relative to the printhead to shift the center of force that loads the printhead against the ribbon and a card that is being printed. The ability to change the location of the application of force on the printhead permits centering the force when a card of different width is fed from a supply through the printhead. Uniform printing will occur on cards regardless of the width, when properly adjusted by the operator.
