Claims
- 1. A family of ink-jet printer cartridges which employ common structural features, the family comprising:
- a first ink cartridge, comprising a first housing structure defining a first set of registration datum structures for registering the position of said first ink cartridge in a printer carriage in relation to X, Y and Z reference axes, a first printhead structure comprising a first headland structure, a first nozzle assembly comprising a first array of nozzles from which ink droplets are emitted during printing operations and a first flexible interconnection circuit, a first ink reservoir system for delivering ink to said printhead structure, and a first supply of liquid ink in the ink reservoir system, wherein each of said nozzles of said first array are fed with ink from said first ink reservoir system; and
- a second ink cartridge, comprising a second housing structure defining a second set of registration datum structures for registering the position of said second ink cartridge in a printer carriage in relation to X, Y and Z reference axes, a second printhead structure comprising a second headland structure, a second nozzle assembly comprising a second array of nozzles from which ink droplets are emitted during printing operations and a second flexible interconnection circuit, a second ink reservoir system for delivering ink to said second printhead structure, and a second supply of liquid ink within said second ink reservoir system, wherein each of said nozzles of said second array are fed with ink from said second ink reservoir system, wherein said first and second housing structures are substantially identical to each other, said first and second registration datum structures are substantially identical to each other, said first and second ink reservoir systems are substantially identical to each other, and said second printhead structure is physically different in a shape or configuration from a corresponding shape or configuration of said first printhead structure, and said first flexible interconnection circuit is physically different from said second flexible interconnection circuit.
- 2. The family of claim 1 wherein said first ink cartridge is adapted for use with a first printer, and said second cartridge is adapted for use with a second, physically different printer.
- 3. The family of claim 2 wherein said first printer includes a first carriage for accepting and making electrical contact with said first ink cartridge, and said second printer includes a second carriage for accepting and making electrical contact with said second cartridge, said second carriage being physically different from said first carriage and wherein the first interconnection circuit is adapted to make said electrical contact with the first carriage, and said second interconnection circuit is adapted to make said electrical contact with the second carriage.
- 4. The family of claim 1 wherein said first flexible interconnection circuit includes a first set of interconnection pads for controlling said first array of nozzles, and said second flexible interconnection circuit includes a second set of interconnection pads for controlling said second array of nozzles, and wherein said second set of interconnection pads includes a greater number of pads than a corresponding number of said first set of interconnection pads.
- 5. The family of claim 4 wherein said first nozzle assembly includes a nozzle pattern for producing a first print resolution, said second nozzle assembly includes a nozzle pattern for producing a second print resolution, and wherein said second print resolution is greater than said first print resolution.
- 6. The cartridge family of claim 1 further comprising a first quantity of ink disposed in said first ink reservoir system and a second quantity of ink disposed in said second ink reservoir system.
- 7. A family of ink-jet printer cartridges which employs common structural features, the family comprising:
- a first ink cartridge, comprising a first set of registration datum structures for registering the position of said first ink cartridge in a printer carriage in relation to X, Y and Z reference axes, a first printhead structure comprising a first headland structure, a first nozzle assembly comprising a first array of nozzles from which ink droplets are emitted during printing operations and a first flexible interconnect structure, a first ink reservoir system for delivering ink to said printhead structure, wherein each of said nozzles of said first array are fed with ink from said first ink reservoir system, an external first rectilinear housing structure for carrying said first set of registration datum structures and enclosing said first reservoir system, and a first snout region protruding from said first housing structure, said first headland region defined in said first snout region; and
- a second ink cartridge, comprising a second set of registration datum structures for registering the position of said second ink cartridge in a printer carriage in relation to X, Y and Z reference axes, a second printhead structure comprising a second headland structure, a second nozzle assembly comprising a second array of nozzles from which ink droplets are emitted during printing operations and a second flexible interconnect structure, a second ink reservoir system for delivering ink to said second printhead structure, wherein each of said nozzles of said second array are fed with ink from said second ink reservoir system, an external second rectilinear housing structure for carrying said second set of registration datum structures and enclosing said second reservoir system, and a second snout region protruding from said second housing structure, said second headland region defined in said second snout region,
- wherein said first rectilinear housing structure is virtually identical to said second rectilinear housing structure in shape and configuration, said first snout region is virtually identical in its shape and configuration to a corresponding shape and configuration of said second snout region, said first and second registration datum structures are virtually identical to each other, said first and second ink reservoir systems are virtually identical to each other, and said second printhead structure is physically different in a shape or configuration from a corresponding shape or configuration of said first printhead structure, said first flexible interconnect structure being physically different from said second flexible interconnect structure, and wherein said first set of datum structures is located well away from said first printhead structure, and said second set of datum structures is located well away from said second printhead structure, permitting modifications to said printhead structures to provide another cartridge in said cartridge family without requiring corresponding modifications to any of said datum structures.
- 8. The family of claim 7 wherein said first ink cartridge is adapted for use with a first printer, and said second cartridge is adapted for use with a second, physically different printer.
- 9. The family of claim 8 wherein said first printer includes a first carriage for accepting and making electrical contact with said first ink cartridge, and said second printer includes a second carriage for accepting and making electrical contact with said second cartridge, said second carriage being physically different from said first carriage and wherein the first interconnect structure is adapted to make said electrical contact with the first carriage, and said second interconnect structure is adapted to make said electrical contact with the second carriage.
- 10. The family of claim 7 wherein said first flexible interconnect structure includes a first set of interconnection pads for controlling said first array of nozzles, and said second flexible interconnect structure includes a second set of interconnection pads for controlling said second array of nozzles, and wherein said second set of interconnection pads includes a greater number of pads than a corresponding number of said first set of interconnection pads.
- 11. The family of claim 10 wherein said first nozzle assembly includes a nozzle pattern for producing a first print resolution, said second nozzle assembly includes a nozzle pattern for producing a second print resolution, and wherein said second print resolution is greater than said first print resolution.
- 12. The cartridge family of claim 7 further comprising a first quantity of ink disposed in said first ink reservoir system and a second quantity of ink disposed in said second ink reservoir system.
