Apparatus controlled by data from consumable parts with incorporated memory devices
First Claim
1. A printing system comprising:
- replaceable cartridge means for housing a supply of consumable marking media and including cartridge memory means for recording printer-related parameters, including marking media parameters;
replaceable print means for producing marks on a print media and including printhead memory means mounted thereon for recording print means-related parameters;
processor means coupled to said cartridge memory means and said printhead memory means and responsive to parameters read from both said cartridge memory means and said printhead memory means for deriving a printer function control value that is dependent upon at least a marking media parameter from said cartridge memory means and a print means-related parameter from said printhead memory means.

Abstract
A printing system includes a replaceable cartridge for housing a supply of consumable marking media. The cartridge includes a cartridge memory for recording printing system-related parameters, including marking media parameters. A replaceable printing device, such as an ink jet head, includes a printhead memory for recording printing device-related parameters. A processor is coupled to the cartridge memory, the printhead memory and is responsive to parameters read from both memories to derive printing system function control values that are dependent upon one or more marking media parameters from the cartridge memory and one or more parameters from the printhead memory. The processor is thus able (in the case of an ink jet printing system) to determine a current ink supply value from a cumulative usage value stored on the cartridge memory and a drop volume parameter stored on the printhead memory. Further, a drop volume parameter stored on the printhead memory can be adjusted to accommodate a media type sensed by a media sensor.

10. A method for controlling operation of a printing system, wherein the printing system includes (i) a replaceable cartridge for housing a supply of consumable marking media, said cartridge further including a cartridge memory mounted thereon for recording printing system-related parameters, including marking media parameters and (ii) replaceable print means for producing marks on a print media and further including a print memory mounted thereon for recording print means-related parameters, the method comprising the steps of:
-
reading parameters stored on both said cartridge memory and said print memory; and deriving a printing system function control value that is dependent upon at least a marking media parameter read from said cartridge memory and a print means-related parameter read said print memory means. - View Dependent Claims (11, 12, 13, 14)

15. A replaceable ink cartridge for an ink jet printing system, the printing system including a replaceable printhead for producing marks on a print media, the replaceable printhead having a printhead memory element mounted thereon for recording print means-related parameters, the printing system including a processor means that is coupled to the printhead memory element when the replaceable printhead is releasably coupled to the printing system, the replaceable ink cartridge comprising:
-
an ink reservoir containing an ink supply; a discharge port in fluid communication with the ink reservoir, the discharge port establishing fluid communication with a fluid inlet in the ink station when the ink cartridge is releasably mounted to the receptacle; and a cartridge memory element mounted thereon and having cartridge-related parameters stored therein, the cartridge memory element electrically coupled with the processor means so that the processor means has access to the cartridge-related parameters when the ink cartridge is installed in the receptacle; wherein, in order to carry out a printing operation where ink is transferred from the ink reservoir through the discharge port to the printhead, certain cartridge-related parameters stored in the cartridge memory element are stored and/or modified by signals from the processor means, and or transmitted from the ink cartridge to the processor means so that the processor means derives a printing system function control value that is dependent upon at least both a cartridge-related parameter and a printhead-related parameter when the replaceable print means and the replaceable ink cartridge are releasably installed in the ink jet printing system. - View Dependent Claims (16, 17, 18, 19)

20. A replaceable ink cartridge for an ink jet printing system, the printing system including a plurality of printheads of different colors for ejecting droplets of ink on media, each printhead including a printhead memory element mounted thereon and having printhead factory parameters stored therein, the printing system having a processor means for controlling printing system function, the processor means coupling with the printhead memory element so that the processor means has access to the printhead factory parameters, the printing system including an ink station for supplying ink to the printhead, the ink station including a plurality of receptacles corresponding to the plurality of printheads, the replaceable ink cartridge comprising:
-
a cartridge body having an ink reservoir therein, the cartridge body adapted to be releasably mounted to one of the plurality of receptacles in said ink jet printing system; a discharge port in fluid communication with the ink reservoir, the discharge port establishing fluid communication with a fluid inlet in one of the plurality of receptacles when the cartridge body is releasably mounted to one of the plurality of receptacles to thereby enable ink to flow out of the discharge port and to an associated printhead when the cartridge body is releasably mounted to one of the plurality of receptacles; and an ink cartridge memory element mounted thereon and adapted to electrically couple to the processor means when the cartridge body is releasably mounted to one of the plurality of receptacles, the ink cartridge memory element thereby providing ink cartridge factory parameters to the processor means; and wherein, in order to carry out a printing operation where ink is transferred from the ink reservoir through the discharge port and to the printhead, certain factory-inserted parameters stored in the ink cartridge memory element are transmitted from the ink cartridge memory element to the processor means so that the processor means combines at least one ink cartridge factory-inserted parameter and at least one printhead factory-inserted parameter to derive a usage control parameter for the printhead. - View Dependent Claims (21, 22, 23, 24)
