Abstract

A media processing device includes: a media processing head; a ribbon transport assembly configured to transport ribbon along a ribbon path between a ribbon dispenser and the media processing head; a graphite applicator disposed along the ribbon path, the graphite applicator configured to apply a combination of graphite and graphene to an active side of the ribbon via frictional engagement with the ribbon; and a media transport assembly configured to transport media from a media supply to the media processing head for transfer of at least a portion of the combination of graphite and graphene from the active side of the ribbon onto the media via application of at least one of heat and pressure at the media processing head.

First claim

The invention claimed is:

1. A media processing device, comprising:
a media processing head;
a ribbon transport assembly configured to transport ribbon along a ribbon path between a ribbon dispenser and the media processing head;
a graphite applicator disposed along the ribbon path, the graphite applicator configured to apply a combination of graphite and graphene to an active side of the ribbon via frictional engagement with the ribbon; and
a media transport assembly configured to transport media from a media supply to the media processing head for transfer of at least a portion of the combination of graphite and graphene from the active side of the ribbon onto the media via application of at least one of heat and pressure at the media processing head.

2. The media processing device of claim 1 , wherein the applicator includes a graphite member disposed in the ribbon path, to deposit the combination onto the active side of the ribbon as the ribbon traverses the applicator.

3. The media processing device of claim 2 , wherein the applicator is a roller.

4. The media processing device of claim 2 , wherein the applicator is static.

5. The media processing device of claim 1 , wherein the applicator is adjacent to the media processing head.

6. The media processing device of claim 1 , wherein the applicator is adjacent to the ribbon.

7. The media processing device of claim 1 , wherein the ribbon dispenser includes a spindle configured to support a roll of ribbon.

8. The media processing device of claim 7 , further comprising a housing, wherein the housing is configured to removably receive at least one of the spindle, a ribbon take-up spindle, or the applicator.

9. The media processing device of claim 1 , wherein the media processing head includes an addressable thermal print head.

10. A media processing device, comprising:
a media processing head;
a supply of ribbon having an active side, at least a portion of the ribbon having a combination of graphite and graphene releasable from the active side, the ribbon dispensable from the supply along a ribbon path towards the media processing head;
a media transport assembly configured to transport media from a media dispenser to the media processing head, for transfer of a portion of the combination of graphite and graphene from the active side of the ribbon onto the media.

11. The media processing device of claim 10 , further comprising an applicator disposed along the ribbon path, the applicator configured to apply the combination of graphite and graphene to the active side of the portion of the ribbon.

12. The media processing device of claim 11 , wherein the applicator includes a graphite member disposed in the ribbon path, to deposit the combination onto the active side of the ribbon as the ribbon traverses the applicator.

13. The media processing device of claim 12 , wherein the applicator is a roller.

14. The media processing device of claim 12 , wherein the applicator is static.

15. The media processing device of claim 10 , wherein the applicator is adjacent to the media processing head.

16. The media processing device of claim 10 , wherein an active side of the ribbon includes a surface treatment to adhere the combination of graphite and graphene.

17. The media processing device of claim 16 , wherein the ribbon includes a substrate, a release coating on a surface of the substrate corresponding to the active side, and the combination of graphite and graphene on the release coating.

18. The media processing device of claim 10 , further comprising a supply of media at the media dispenser, the media including a surface treatment configured to adhere the combination of graphite and graphene.

19. A method in a media processing device, the method comprising:
controlling a ribbon transport assembly to transport a ribbon along a ribbon path from a ribbon dispenser toward a media processing head;
at a graphite applicator between the ribbon dispenser and the media processing head, applying a combination of graphite and graphene to an active side of the ribbon via frictional engagement with the ribbon;
controlling a media transport assembly to transport media from a media supply to the media processing head; and
controlling the media processing head to transfer at least a portion of the combination of graphite and graphene from the active side of the ribbon to the media.
