Abstract
Abstract A liquid delivery system for delivering inks of three or more different colors or densities or dye-forming reactive components comprising multiple liquid reservoirs, liquid bladders, and valves that permit (a) total interruption of liquid flow, (b) liquid flow from reservoirs to bladders and (c) flow of liquid from bladders to printhead, the latter adapted to handle toners of three different colors, optical densities or chemical composition. The valves and ink flow channels are arranged in an upper manifold, gasket and lower manifold, all of which serve as support for the bladders and dimpler system.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
132 words
A liquid delivery system for an ink-jet printer, said system having refillable bladders having in combination: (a) multiple reservoirs for storing quantities of different liquids; (b) a printhead capable of delivering separately each of said different liquids to a printing medium; (c) a bladder for each of said different liquids for providing a supply of said liquid at a known back pressure to predetermined jets in a printhead; (d) a valve associated with each bladder and an inlet means and an outlet means for providing a closed mode, a refill mode for conveying liquid from a reservoir to said bladder, and a print mode for conveying said liquid from said bladder to said printhead; and (e) support means for maintaining said reservoirs, said printhead, said bladders, and said valves in cooperative association.
Claim 2
Dependent Claim
132 words
A liquid delivery system for an ink-jet printer, said system having refillable bladders having in combination: (a) multiple reservoirs for storing quantities of different liquids; (b) a printhead capable of delivering separately each of said different liquids to a printing medium; (c) a bladder for each of said different liquids for providing a supply of said liquid at a known back pressure to predetermined jets in a printhead; (d) a valve associated with each bladder and an inlet means and an outlet means for providing a closed mode, a refill mode for conveying liquid from a reservoir to said bladder, and a print mode for conveying said liquid from said bladder to said printhead; and (e) support means for maintaining said reservoirs, said printhead, said bladders, and said valves in cooperative association.
Claim 3
Dependent Claim
14 words
A delivery system of claim 1 wherein said bladders are molded from elastomeric material.
Claim 4
Dependent Claim
24 words
A delivery system of claim 1 wherein said inlet means and said outlet means, are grooves cut into the under-surface of a top manifold.
Claim 5
Dependent Claim
14 words
A delivery system of claim 1 wherein the reservoirs contain inks of different colors.
Claim 6
Dependent Claim

Claim 8
Dependent Claim
124 words
A tricolor ink delivery system having refillable bladders, having in combination: (a) three ink reservoirs for storing quantitites of different colored inks; (b) a printhead capable of delivering inks of at least three different colors to a printing medium; (c) three bladders for providing a supply of ink at a known back pressure of a selected color from each of said bladders to predetermined jets in a print head; (d) a valve associated with each bladder for providing a closed mode, a refill mode for conveying ink from a reservoir to said bladder, and a print mode for conveying ink from said bladder to said printhead; and (e) support means for maintaining said reservoir, said printhead, said bladders and said valves in cooperative association.
Claim 9
Dependent Claim
124 words
A tricolor ink delivery system having refillable bladders, having in combination: (a) three ink reservoirs for storing quantitites of different colored inks; (b) a printhead capable of delivering inks of at least three different colors to a printing medium; (c) three bladders for providing a supply of ink at a known back pressure of a selected color from each of said bladders to predetermined jets in a print head; (d) a valve associated with each bladder for providing a closed mode, a refill mode for conveying ink from a reservoir to said bladder, and a print mode for conveying ink from said bladder to said printhead; and (e) support means for maintaining said reservoir, said printhead, said bladders and said valves in cooperative association.
Claim 10
Dependent Claim
