Jul 30, 2002

Appl. No.:

10/208956

Inventors:

Mark L McCarty - Corvallis OR

Assignee:

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

International Classification:

B41J 2165

US Classification:

347 29, 347 85, 347 86, 347 89

Abstract:

An ink delivery device is provided for supplying ink via an ink conduit from an ink supply to a print head attached to a manifold, the manifold adapted to route ink into the print head and back to the ink conduit for routing to the ink supply. The ink delivery device comprises a pressure controller operating on the ink conduit between the print head and the ink supply, the pressure controller including a sealing device adapted to seal off the ink conduit and a cap adapted to selectably expose the pressure controller to ambient conditions. The pressure controller is adapted to purge the print head of ink between print jobs.

International Classification:

B41J 2175

US Classification:

347 87

Abstract:

The back pressure of an ink pen is maintained by providing a capillary member adjacent a bubble generator. Regardless of the orientation of the pen, the capillary member maintains a quantity of ink adjacent an orifice defined by the bubble generator. The quantity of ink serves to supply a liquid seal formed in the orifice. As the back pressure within the ink pen rises to its maximum level, the liquid seal within the orifice is overcome and ambient air bubbles into the reservoir to lower the back pressure. As the back pressure returns to a desirable point, ink trapped by the capillary member enters the orifice to reseal the orifice.
