  • Method of manufacture for ink-jet hard copy apparatus using a modular approach to ink-jet technology
    Patent number: 6493937
    Abstract: A manufacturing method provides ink-jet writing engine modules for use with a compatible hard copy engine module, a hard copy apparatus based thereon, and methods of manufacturing, operation, and use. Fluidic and electronic partitioning for ink-jet hard copy apparatus is redefined. Modular separation of a hard copy engine from a writing engine allows a replaceable writing module containing all of the key elements of the ink-jet writing system based on writing system technology requirements, particularly for those most likely to age or fail as a result of time, frequency of use, or end-user actions.
    Type: Grant
    Filed: March 16, 1998
    Date of Patent: December 17, 2002
    Assignee: Hewlett-Packard Company
    Inventors: James P Axtell, Trudy L Benjamin, David J Lowe, Preston D. Seu, Blair M. Kent
