Abstract

A printing cartridge includes a housing and a print media roller, carrying a roll of print media is positioned and rotated in the house. A radio frequency tag is positioned on the housing. The radio frequency tag carries data relating to at least one of: a serial number of the cartridge, a media and a media colorant.

Claims

1. A printing cartridge for an ink jet printer having a body, the body housing a printhead that includes at least one ink jet printhead chip that incorrates a plurality of nozzle arrangements, each nozzle arrangement being in the form of a micro-electromechanical device and each nozzle arrangement being connected to a microprocessor that is configured to control operation of each nozzle arrangement, the printing cartridge comprising:

a housing that is engageble with the printer;

print media roller that is positioned in the housing and is rotatable with respect to the housing, the print media roller carrying a roll of media and being hollow to define a cavity;

an ink reservoir arrangement that is positioned in the cavity, the ink reservoir arrangment being configured to store at least one form of ink;

an ink conduit arrangement that is positioned in the cavity to be in fluid communication with the ink reservoir arrangement, the ink conduit arrangement being engageable with a complementary ink conduit arrangement of the printer to supply the printhead with ink;

a radio frequency tag positioned on the housing, the radio frequency tag carrying data relating to the media and to the ink stored in the reservoir arrangement, the radio frequency tag being actuable to generate a signal that is capable of being read by the printer and conveyed to the microprocessor so that the microprocessor can adjust operation of thee nozzle arrangements in accordance with the type of media and ink carried in the cartridge.

2. A printing cartridge as claimed in claim 1, wherein the radio frequency tag carries data related to at least one of:

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

3. A printing cartridge as claimed in claim 1, in which the data carried by the radio frequency tag is protected with an encryption algorithm.

4. A printing cartridge as claimed in claim 1, in which the radio frequency tag is passive, being of a type which is energized by a reader.

5. A printing cartridge as claimed in claim 1, in which the radio frequency tag includes a transponder which carries the data and an antenna-capacitor circuit for powering the transponder.

6. An ink jet printer which comprises

a body,

a pagewidth printhead that is housed in the body, the printhead including at least one ink jet printhead chip that incorporates a plurality of micro-electromechanical nozzle arrangements that are in fluid communication with an ink supply arrangement;

a microprocessor that is also positioned in the housing, the microprocessor being operatively connected to the printhead to control operation of each nozzle arrangernent;

a printing cartridge that is engaged with the body, the printing cartridge comprising;

a housing,

a print media roller that is positioned in the housing and is rotatable with respect to the housing, the print media roller carrying a roll of print media and being hollow to define a cavity;

an ink reservoir arrangement that is positioned in the cavity, the ink reservoir arrangement being configured to store at least one form of ink;

an ink conduit arrangement that is positioned in the cavity to be in fluid communication with the ink reservoir arrangement and with the ink supply arrangement so that ink from the ink reservoir arrangement can be supplied to the printhead; and

a radio frequency tag that is positioned on the housing and carries data relating to the ink and the media; and

a radio frequency tag reader positioned in the body to read the radio frequency tag and to provide the microprocessor with data carried in a signal received from the radio frequency tag, the microprocessor being configured to adjust operation of the nozzle arrangements in accordance with the type of ink and print media.

7. A printing device as claimed in claim 6, in which the radio frequency tag reader is configured to operate with a passive radio frequency tag.

8. A printing device as claimed in claim 7, in which the radio frequency tag reader includes an antenna-capacitor circuit for emitting a radio wave field for powering the radio frequency tag.

9. A printing device as claimed in claim 7, 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 microprocessor.
