Abstract

A printer cartridge for an inkjet printer including a printing fluid storage and a pagewidth printhead in communication with said printing fluid storage.

Claims (19)

1. A cartridge for an inkjet printer that has a media feed path, the cartridge comprising:

a casing that houses a printing fluid storage that defines an enclosed volume for holding a supply of printing fluid; and,

a pagewidth printhead mounted to the casing in fluid communication with the printing fluid storage; wherein,

the casing is configured for releasable engagement with the inkjet printer such that the casing and all the pagewidth printhead are simultaneously user removable and replaceable as a single component.

2. A printer cartridge according to claim 1 , wherein the pagewidth printhead is arranged to generate a print of at least 8 inches in width.

3. A printer cartridge according to claim 1 wherein the printing fluid storage is housed within a body that includes an arrangement for replenishing of printing fluid from an external source.

4. A printer cartridge according to claim 1 , wherein the pagewidth printhead includes at least 20,000 printing fluid delivery nozzles in fluid communication with the printing fluid storage.

5. A printer cartridge according to claim 4 , wherein the pagewidth printhead includes at least 30,000 printing fluid delivery nozzles in fluid communication with the printing fluid storage.

6. A printer cartridge according to any of claims 2 to 5 , or 1 wherein the printing fluid storage includes one or more storage reservoirs for storing an ink for printing.

7. A printer cartridge according to claim 6 , wherein the one or more storage reservoirs separately store a set of colored inks sufficient for color printing.

8. A printer cartridge according to claim 7 , wherein the one or more storage reservoirs also separately store an ink fixative to aid in fixing the ink delivered by the pagewidth printhead.

9. A printer cartridge according to claim 8 , wherein the one or more storage reservoirs separately store an infra-red ink for printing.

10. A printer cartridge according to claim 9 , further comprising an electrical connector in electrical communication with the pagewidth printhead, the electrical connector being disposed on the casing wherein the electrical connector has a first electrical connector disposed adjacent a first end of the pagewidth printhead and the corresponding connector in the inkjet printer has a first corresponding connector for mating with the first electrical connector when the casing engages the complementary recess.

11. A printer cartridge according to claim 10 , wherein the electrical connector has a second electrical connector disposed adjacent a second end of the pagewidth printhead and the corresponding connector in the inkjet printer has a second corresponding connector of the inkjet printer for mating with the first electrical connector when the casing engages the complementary recess.

12. A printer cartridge according to claim 10 or 11 , wherein printer power and data is transmitted to the pagewidth printhead from the inkjet printer by through the first and second electrical connectors.

13. A printer cartridge according to claim 12 , wherein the cartridge includes an assembly arranged to direct air over said pagewidth printhead.

14. A printer cartridge according to claim 13 , wherein the assembly includes a filter for filtering the air prior to said air being directed over said pagewidth printhead.

15. A printer cartridge according to claim 14 , wherein the assembly includes an inlet for receiving air from an external source.
