  • Ink interconnect between print cartridge and carriage
    Publication number: 20020149646
    Abstract: In the preferred embodiment, an inkjet printer includes a replaceable print cartridge which is inserted into a scanning carriage. An ink tube extends from the scanning carriage to a separate ink supply located within the printer. A fluid interconnect on one side of the print cartridge connects to a fluid interconnect on the carriage when the print cartridge is inserted into the carriage to complete the fluid connection between the external ink supply and the print cartridge. In one embodiment, the fluid interconnection is made between the print cartridge and the ink tube simply by placing the print cartridge into a stall in the scanning carriage. The print cartridge has contact pads on another side. The contact pads electrically contact electrodes on the carriage when the print cartridge is placed in the stall.
