09/547271

Inventors:

Charles R. Steinmetz - Corvallis OR
Scott D. Sturgeon - Vancouver WA
David C. Johnson - Portland OR
Jeffrey T. Hendricks - Camas WA

Assignee:

Hewlett-Packard Company - Fort Collins CO

International Classification:

B41J 2175

US Classification:

347 86, 347 85

Abstract:

A replaceable ink container for providing ink to an inkjet printing system. The inkjet printing system has a receiving station that is mounted to a scanning carriage. The receiving station has a keyed portion being indicative of a replaceable ink container parameter of a plurality of replaceable ink container parameters. The replaceable ink container includes a reservoir portion having a leading end and a trailing end relative to an insertion direction into the receiving station. Also included is a keying portion disposed on the trailing end and configured to be complementary to the keyed portion thereby allowing the replaceable ink container to be fully inserted into the receiving station.

International Classification:

B41J 2175

US Classification:

347 85

Abstract:

Disclosed is a manifold providing fluid connections between a plurality of carriage-mounted ink reservoirs and multiple carriage-mounted printheads, the manifold having ink conduits allowing the spacing, ordering, or number of printheads to differ from the spacing, ordering, or number of ink reservoirs. The manifold also serves to mechanically isolate the printheads from the ink reservoirs, such that replacement of one or more reservoir does not adversely affect the alignment of the printheads. The manifold allows simple optimization of a printing system to a particular application by replacing the manifold with one of a different configuration.

International Classification:

B41J 2175

US Classification:

347 86, 347 50

Abstract:

The present disclosure relates to a replaceable ink reservoir for installation into a printing system that has a moveable carriage for repositioning a printing portion relative to print media. The replaceable ink reservoir includes an ink reservoir that does not have an integral printing portion. Also included is an electrical storage device for storing information. The installation of the ink reservoir into the moveable carriage establishes both fluid communication between the ink reservoir and the moveable carriage and establishes electrical continuity between the electrical storage device and the moveable carriage.

Assignee:

Hewlett-Packard Company - Palo Alto CA

International Classification:

B41J 2175

US Classification:

347 86

Abstract:

The present invention disclosure relates to a replaceable ink container for providing ink to an inkjet printing system. The inkjet printing system has a receiving station mounted to a scanning carriage. The receiving station has a fluid inlet and a pair of guide rails extending along either side of the fluid inlet. The replaceable ink container includes a fluid outlet configured for connection to the fluid inlet associated with the receiving station. Also included is a pair of outwardly extending guide rail engagement features. Each of the pair of guide rail engagement features are so disposed and arranged on the replaceable ink container for engagement with each of the pair of guide rails to guide the replaceable ink container in both horizontal and vertical directions into the receiving station. The pair of outwardly extending guide rail engagement features and the pair of guide rails cooperate to align the fluid outlet with the fluid inlet to establish fluid communication between the ink container and the receiving station.

Inventors:

Scott D. Sturgeon - Vancouver WA
David C. Johnson - Portland OR

Assignee:

Hewlett-Packard Development Company, L.P. - Houston TX

International Classification:

H01R 448

US Classification:

439862, 439660

Abstract:

An electrical connector configured for minimized contact with a non-target structure of a target circuit, and a printing mechanism that uses the electrical connector for conductive connection between circuit portions of the printing mechanism. The connector includes a housing for positioning the connector in conductive contact with the target circuit. An electrically conductive contact filament is mounted on the housing and includes a proximal portion extending from the housing and a contact portion for electrically contacting the target circuit. An intermediate portion is formed to circumnavigate the non-target structure and joins the proximal and distal portions.

Assignee:

Hewlett-Packard Development Company, L.P. - Houston TX

International Classification:

H01R 1364

US Classification:

439247, 439295, 439552, 439571

Abstract:

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.

Assignee:

Hewlett-Packard Development Company, L.P. - Houston TX

International Classification:

B41J 201

US Classification:

347 49

Abstract:

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.

International Classification:

B41J 2175

US Classification:

347 86, 347 45

Abstract:

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.
