  • Patent number: 6817697
    Abstract: The present invention is directed to systems and methods for formatting hardware for a printhead, for use in a printing device. The systems and methods of the present invention can support the formatting function with hardware formatting logic. This hardware formatting logic can support multiple printhead platforms. The hardware formatting logic of the present invention can perform bit shifting, resolution reduction, bit per pixel reduction, data masking for shingling, and input data sourcing. The present invention can also include a system processor further including an embedded ARM processor which can fetch and execute instructions and/or firmware. These instructions can direct the embedded processor to configure a format block included within the system processor. The format block can be configured by the system processor via one or more control registers.

  • Patent number: 6145971
    Abstract: A system and method for supplying ink to a print head on a moving carrier using the acceleration of the print head carrier to assist in pumping the ink. The system includes an ink supply reservoir and an ink pump on the moving carrier where the ink pump has a carrier reservoir including at least one flexible wall that deforms from inertial resistance to acceleration of the moving carrier, a print head, and a pressure regulator in fluid communication with the carrier reservoir and the print head. The system also has an ink supply tube in fluid communication with the ink supply reservoir and the carrier reservoir such that acceleration of the moving carrier and ink pump deforms the flexible wall and thereby pumps ink from the ink supply reservoir to the carrier reservoir and from the carrier reservoir to the print head, or solely to the carrier reservoir.
