US Patent:

57369984, Apr 7, 1998

Filed:

Mar 6, 1995

Appl. No.:

8/398849

Inventors:

Michael P. Caren - Palo Alto CA
Max Stephen Gunther - San Diego CA
John C. Nadworny - San Diego CA

Assignee:

Hewlett-Packard Company - Palo Alto CA

International Classification:

B41J 2135

US Classification:

347 45

Abstract:

This disclosure describes an improved ink seal between a print cartridge body and an inkjet printhead. In a preferred embodiment, a nozzle member containing an array of orifices has a substrate, having heater elements formed thereon, affixed to a back surface of the nozzle member. Each orifice in the nozzle member is associated with a single heating element formed on the substrate. The back surface of the nozzle member extends beyond the outer edges of the substrate. Ink is supplied from an ink reservoir to the orifices by a fluid channel within a barrier layer between the nozzle member and the substrate. The fluid channel in the barrier layer may receive ink fl owing around two or more outer edges of the substrate or may receive ink which flows through a hole in the center of the substrate. The nozzle member is adhesively sealed with respect to the ink reservoir body by forming an ink seal circumscribing the substrate, between the back surface of the nozzle member and the headland area of the print cartridge. This method and structure for a print cartridge headland for providing a seal directly between a nozzle member and an ink reservoir body has many advantages over other methods of providing a seal between a printhead and the ink reservoir body.

Abstract:

Techniques for managing secure login with authentication while viewing a unique code are described. In some examples, a requesting device displays a visual representation of data. An authenticating device detects the presence of the visual representation of data. The authenticating device prompts a user to provide authorization information at the authenticating device. The authenticating device receives a set of one or more inputs. The authenticating device transmits information authorizing access to content on the requesting device.
