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.
A printing system comprising:
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:
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:
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:
