Abstract

A print cartridge including a cartridge body, a fluid reservoir disposed within the cartridge body that receives and contains fluid, a fluid ejector chip comprising a plurality of heating elements that eject the fluid from the print cartridge, and a memory device that stores first data related to information regarding the number of times the print cartridge was remanufactured and second data related to information regarding the print yield of the print cartridge for each instance of cartridge remanufacture.

First claim

1 . A print cartridge comprising:
a cartridge body; a fluid reservoir disposed within the cartridge body that receives and contains fluid; a fluid ejector chip comprising a plurality of heating elements that eject the fluid from the print cartridge; and a memory device that stores first data related to information regarding the number of times the print cartridge was remanufactured and second data related to information regarding the print yield of the print cartridge at a time of cartridge remanufacture for each instance of cartridge remanufacture.

2 . The print cartridge of claim 1 , wherein the first data comprises one or more first data fields, each first data field comprising a data bit set to indicate whether the print cartridge is either new or remanufactured.

3 . The print cartridge of claim 2 , wherein the number of data bits set to indicate that the print cartridge is remanufactured corresponds to the number of times the print cartridge was remanufactured.

4 . The print cartridge of claim 1 , wherein the second data comprises one or more second data fields, each data field corresponding to an instance of cartridge remanufacture and comprising one or more data bits that indicate print yield for the instance of cartridge remanufacture.

5 . The print cartridge of claim 1 , wherein the print yield corresponds to the maximum number of pages that can be printed using the print cartridge.

6 . The print cartridge of claim 1 , wherein the print yield corresponds to the maximum amount of fluid that can be ejected from the print cartridge.

7 . The print cartridge of claim 1 , wherein the print yield corresponds to the maximum number of drop counts of fluid ejected from the print cartridge.

8 . An inkjet printer comprising:
a housing; a carriage adapted to reciprocate along a shaft disposed within the housing; one or more printhead assemblies arranged on the carriage so that the one or more printhead assemblies eject ink onto a print medium as the carriage reciprocates along the shaft in accordance with a control mechanism, wherein at least one of the one or more printhead assemblies comprises: a printhead cartridge comprising:
a cartridge body;
an ink reservoir disposed within the cartridge body that receives and contains ink;
an ink ejector chip comprising a plurality of heating elements that eject the ink from the ink reservoir; and
a memory device that stores first data related to information regarding the number of times the printhead cartridge was remanufactured and second data related to information regarding the print yield of the printhead cartridge at a time of cartridge remanufacture for each instance of cartridge remanufacture.

9 . The inkjet printer of claim 8 , wherein the first data comprises one or more first data fields, each first data field comprising a data bit set to indicate whether the printhead cartridge is either new or remanufactured.

10 . The inkjet printer of claim 9 , wherein the number of data bits set to indicate that the printhead cartridge is remanufactured corresponds to the number of times the printhead cartridge was remanufactured.

11 . The inkjet printer of claim 8 , wherein the second data comprises one or more second data fields, each data field corresponding to an instance of cartridge remanufacture and comprising one or more data bits that indicate print yield for the instance of cartridge remanufacture.

12 . The inkjet printer of claim 8 , wherein the print yield corresponds to the maximum number of pages that can be printed using the printhead cartridge.

13 . The inkjet printer of claim 8 , wherein the print yield corresponds to the maximum amount of fluid that can be ejected from the printhead cartridge.

14 . The inkjet printer of claim 8 , wherein the print yield corresponds to the maximum number of drop counts of fluid ejected from the printhead cartridge.
