Abstract

A system and method for controlling image transfer device operations through use of sensed indicia disposed on at least one edge of the image transfer medium. A signal responsive to the sensed indicia is produced and transferred to a control signal. The control signal is recognizable by the image transfer device for controlling print operations, thereby configuring the device for the specific media being utilized. In a preferred embodiment of the invention indicia are placed on the four edges of the media. The indicia can be in the form of a bar code encoding such information as brand, media type, orientation, and size. Preferably the indicia include nonvisible, fluorescing ink.

Claims

1. A method of controlling operation of an image transfer device, comprising the steps of:

providing an image transfer medium, said medium having a top surface, a bottom surface and a plurality of edges integrally disposed between said top surface and said bottom surface, said medium further having signal generating indicia disposed on at least some of said plurality of edges;

providing an image transfer device having a sensor for detecting a signal generated by said indicia; and

converting the detected signal into a command signal for controlling image transfer device operation.

2. The method according to claim 1, including the step of providing an image transfer medium having said signal generating indicia disposed on four edges thereof.

3. The method according to claim 1, including the step of providing an image transfer medium having said signal generating indicia disposed on eight edge locations thereof.

4. The method according to claim 1, including the step of providing an image transfer medium having said signal generating indicia disposed in separated relationship on at least one of said plurality of edges.

5. The method according to claim 1, including the step of using a fluorescing ink as the signal generating indicia.

6. The method according to claim 1, including the step of using an infrared ink as the signal generating indicia.

7. The method according to claim 1, including the step of providing an image transfer medium having signal generating indicia in bar code format.

8. A system for controlling operations of an image transfer device, comprising:

image transfer medium, said medium having a top surface, a bottom surface and a plurality of edges integrally disposed between said top surface and said bottom surface, said medium including signal generating indicia disposed on at least some of said plurality of edges;

means for sensing a signal generated by said indicia;

means for producing a control signal responsive to the sensed indicia; and

means for operating the image transfer device responsive to the control signal.

9. The system according to claim 8, wherein said indicia are disposed on four edges of said image transfer medium.

10. The system according to claim 8, wherein said indicia are disposed on eight edge locations of said image transfer medium.

11. The system according to claim 8, wherein said indicia are disposed in separated relationship on at least one of said plurality of edges on said image transfer medium.

12. The system according to claim 8, wherein said indicia include fluorescing ink.

13. The system according to claim 8, wherein said indicia include an infrared ink.

14. The system according to claim 8, wherein said image transfer device is a printer, photocopier, scanner, or facsimile device.

15. The system according to claim 8, wherein said image transfer medium is paper or plastic.

16. The system according to claim 8, wherein said indicia include material in bar code format.

17. The system according to claim 8, including means for displaying image transfer medium type and orientation.

18. The system according to claim 8, including means, responsive to said control signal, for controlling image transfer device print mode.

19. The system according to claim 8, wherein said means for sensing includes a plurality of sensors.

20. The system according to claim 19, wherein one of said plurality of sensors includes means for sensing distance of travel of said image transfer medium in said image transfer device.

21. The system according to claim 20, including means responsive to said distance measuring means for adjusting image transfer device print mode.
