Abstract

A printing cartridge (1230) includes a housing (1234). A radio frequency tag (1232) is positioned on the housing (1234). The radio frequency tag (1232) carries data relating to at least one of a serial number of the cartridge, a media and a media colorant.

Claims

1. A method of determining media of a printing cartridge, the method comprising the step of reading a radio frequency tag positioned on a housing of the printing cartridge with a radio frequency tag reader positioned in a printing device with which the printing cartridge is engaged, the radio frequency tag carrying data relating to the media of the printing cartridge.

2. A printing cartridge that comprises

a housing;

a media supply arrangement positioned within the housing and containing a supply of media; and

a radio frequency tag positioned on the housing, the radio frequency tag carrying data relating to the media.

3. A printing cartridge as claimed in claim 2, wherein the radio frequency tag carries data related to at least one of a serial number identifying the media, a type of the media and a length of the media.

4. A printing cartridge as claimed in claim 2, in which the data carried by the radio frequency tag is encrypted with an encryption algorithm.

5. A printing cartridge as claimed in claim 2, in which the radio frequency tag is passive, being of a type which is energized by a reader.

6. A printing cartridge as claimed in claim 5, in which the radio frequency tag includes a transponder which carries the data and an antenna-capacitor circuit for powering the transponder.

7. A method of determining media and media colorant of a printing cartridge, the method comprising the step of reading a radio frequency tag positioned on a housing of the printing cartridge with a radio frequency tag reader positioned in a printing device with which the printing cartridge is engaged, the radio frequency tag carrying data relating to the media and the media colorant of the printing cartridge.

8. A printing cartridge that comprises

a housing;

media and media colorant supply arrangements positioned within the housing and containing a supply of media and a supply of media colorant, respectively; and

a radio frequency tag positioned on the housing, the radio frequency tag carrying data relating to the media and the media colorant.

9. A printing cartridge as claimed in claim 8, wherein the radio frequency tag carries data related to at least one of:

a serial number identifying the media, a serial number identifying the media colorant, a length of the media, a type of the media, a viscosity of the media colorant, a surface tension of the media colorant, optical characteristics of the media colorant and an optimal ink drop volume of the media colorant corresponding to the type of media.

10. A printing cartridge as claimed in claim 8, in which the data carried by the radio frequency tag is protected with an encryption algorithm.

11. A printing cartridge as claimed in claim 8, in which the radio frequency tag is passive, being of a type which is energized by a reader.

12. A printing cartridge as claimed in claim 11, in which the radio frequency tag includes a transponder which carries the data and an antenna-capacitor circuit for powering the transponder.

13. A printing device which comprises

a body, a printing cartridge being engageable with the body, the printing cartridge having a housing, a media supply arrangement positioned within the housing and containing a supply of media, a radio frequency tag being positioned on the housing and carrying data relating to the media;

a processor positioned in the body to control operation of a media feed mechanism and a printing mechanism; and

a radio frequency tag reader positioned in the body to read the radio frequency tag and to provide the processor with data carried in a signal received from the radio frequency tag.

14. A printing device as claimed in claim 13, in which the radio frequency tag reader is configured to operate with a passive radio frequency tag.

15. A printing device as claimed in claim 14, in which the radio frequency tag reader includes an antenna-capacitor circuit for emitting a radio wave field for powering the radio frequency tag.

16. A printing device as claimed in claim 13, in which the radio frequency tag reader incorporates circuitry for decoding the signal received from the radio frequency tag into data that is readable by the processor.

17. A printing device which comprises

a body, a printing cartridge being engageable with the body, the printing cartridge having a housing, media colorant and media supply arrangements positioned within the housing and containing a supply of media and media colorant, a radio frequency tag being positioned on the housing and carrying data relating to the media colorant and the media;

a processor positioned in the body to control operation of media colorant and media feed mechanisms and a printing mechanism; and

a radio frequency tag reader positioned in the body to read the radio frequency tag and to provide the processor with data carried in a signal received from the radio frequency tag.

18. A printing device as claimed in claim 17, in which the radio frequency tag reader is configured to operate with a passive radio frequency tag.

19. A printing device as claimed in claim 18, in which the radio frequency tag reader includes an antenna-capacitor circuit for emitting a radio wave field for powering the radio frequency tag.

20. A printing device as claimed in claim 18, in which the radio frequency tag reader incorporates circuitry for decoding the sign received from the radio frequency tag into data that is readable by the processor.
