  • Method and apparatus for actuating a pump in a printer
    Patent number: 6220699
    Abstract: A printer apparatus and method of actuating a fluid pump in a printer to deliver fluid to an ink jet printhead without removing the printhead from a printhead carriage particularly useful for priming inkjet printheads using an air displacement pump to deliver air under positive pressure to the printheads. The pump is located proximate a service station on the printer and is automatically actuated by movement of the carriage to service station. The pump may be arcuately positionable to align the pump with a selected one of air passageways provided in a printhead holddown cover on the printhead carriage. Algorithms are provided for locating the precise position of the pump outlet along the carriage scan axis relative to its intended design location and for arcuately positioning the pump relative to the carriage to engage the pump outlet with a selected one of conduits in the carriage connected to each printhead.
