Patent number: 7156491Abstract: A separable key element operably secured to a printer component base for receiving a key from a printer component to be received therein. The key indicates a required characteristic of the printer component thereby allowing only compatible printer components to be installed onto the printer component base. The key element can matingly engage the printer component base in a unique configuration such that only compatible key elements can be secured to the printer component base. Moreover, the key element can include a display surface for visually identifying the required characteristic of the printer component. In a preferred embodiment, the printer component is a detachable ink reservoir and the printer component base is secured to the carriage of an inkjet printer, thereby providing an on-axis ink reservoir.Type: GrantFiled: April 30, 2004Date of Patent: January 2, 2007Assignee: Hewlett-Packard Development Company, L.P.Inventors: Scott D.

Patent number: 6779874Abstract: A partial mounting portion cover that extends above and partially over the front portion of a chamber for operably receiving a detachable printer component therein. The cover includes a substantially planar top surface positioned over the toe-end of the detachable printer component when the printer component is fully installed on the mounting portion, such that the cover extends over the printer component only by an amount that precludes the cover from interfering with a toe-heel installation process. Accordingly, so long as the installer mounts the toe-end of the detachable printer component first, the mounting portion cover does not interfere with the installation. However, if an installer attempts to install the printer component in another manner, the cover blocks the toe-end of the printer component from entering the chamber, thereby alerting the installer of the improper installation method.Type: GrantFiled: July 31, 2001Date of Patent: August 24, 2004Assignee: Hewlett-Packard Development Company, LP.Inventors: Scott D. Sturgeon, David C. Johnson, Lisa M. Hanson

Patent number: 6755516Abstract: The present disclosure relates to a replaceable ink container for providing ink to an inkjet printing system. The inkjet printing system has a receiving station for receiving the replaceable ink container. The replaceable ink container includes a handle extending from a trailing end of the ink container for grasping the ink container for insertion into the receiving station. Also included is a latch for securing the replaceable ink container to the receiving station. The latch has an extended position for engaging the receiving station for securing the ink container to the receiving station and a retracted position. The latch is so disposed and arranged on the ink container to be urged from the extended position to the retracted position as the handle is grasped.Type: GrantFiled: May 16, 2002Date of Patent: June 29, 2004Assignee: Hewlett-Packard Development Company, L.P.Inventors: Lisa M.

Patent number: 6749292Abstract: The present disclosure relates to an ink container to be received within a receiving station of an inkjet printing system. The receiving station has a fluid inlet having a compliant seal and a pair of guide slots extending along either side of the fluid inlet. The ink container includes a guide feature outwardly extending therefrom. The guide feature is disposed toward a trailing end relative to an insertion direction. The guide feature is configured to cooperate with the at least one guide slot to guide the ink container in a pivot motion to ensure the ink container engages the compliant seal forming a seal therewith.Type: GrantFiled: October 18, 2001Date of Patent: June 15, 2004Assignee: Hewlett-Packard Development Company, L.P.Inventors: Scott D.

Patent number: 6676426Abstract: An electrical connector is positioned in a biased manner relative to a receptacle upon mating. The mated electrical connector is positioned along a first positioning axis of the receptacle in predetermined electrical contact with a target circuit. The connector includes a housing that mates with the receptacle along a mating axis and is placed at a predetermined position along an orthogonal first positioning axis. The housing also defines a first-positioning-axis datum which engages the receptacle. Furthermore, the connector includes an electrically conductive contact structure mounted on the housing, and a biasing mechanism operatively coupled with the housing. The biasing mechanism acts to maintain the first-positioning-axis datum in abutment with the receptacle upon mating of the housing with the receptacle.Type: GrantFiled: August 9, 2001Date of Patent: January 13, 2004Assignee: Hewlett-Packard Development Company, L.P.Inventors: Scott D.
