Filed:

Apr 23, 2002

Appl. No.:

10/127885

Inventors:

Eric S. Dod - Corvallis OR
Ralph L. Stathem - Lebanon OR
Gregory W. Blythe - Philomath OR

Assignee:

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

International Classification:

B41J 2175

US Classification:

347 85, 347 47

Abstract:

A marking fluid valve for a marking fluid delivery system of a media marking device. The marking fluid valve includes a resilient body having first and second opposite ends in fluid communication with one another, with the first end having a pair of opposed lips. The pair of opposed lips define a normally closed slit extending therebetween. Compressing the first end of the resilient body along axes of the lips deforms the resilient body from a closed position, in which the lips are in contact with one another to close the slit and prevent marking fluid from passing through the slit, to an open position, in which the lips are spread at least partially apart from one another to enable marking fluid to pass through the slit.

Assignee:

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

International Classification:

B41J 2175

US Classification:

347 85

Abstract:

A rejuvenation station has a housing with a first area adapted to hold a fluid supply, and a second area adapted to hold a printer cartridge. In the first area is a first fluidic interconnect that is adapted to couple with the fluid supply. In the second area is a second fluidic interconnect that is adapted to couple with the printer cartridge. A fluid path in the housing couples the fluidic interconnects. An actuator extracts fluid from at least one of the fluid supply and the printer cartridge, and inserts fluid into the printer cartridge through the fluid path.
