Abstract

A system and method for controlling image transfer device operations through use of a medium marking material on the image transfer medium being printed. The medium marking material is coded on the paper and sensed by the transfer device to control operations. The medium marking material is visible and/or legible to an operator prior to printing, but becomes invisible during or after printing operations. Responsive to the marking material sensed, a marking signal is produced and translated to a command signal recognized by the printer for controlling printer operations. Heat generated by the printing process causes the marking material to become virtually indistinguishable from the paper during/after printer operations.

Claims

1. A method of controlling operations of an image transfer device through use of a medium marking material on an image transfer medium used in connection with the image transfer device, the method comprising:

(a) sensing the medium marking material on the image transfer medium, for producing a marking signal;

(b) operating the image transfer device responsive to the marking signal; and

,

(c) rendering the medium marking material virtually indistinguishable from the image transfer medium.

2. The method of claim 1 further including translating the marking signal to a command signal recognizable by the image transfer device for operating the image transfer device.

3. The method of claim 1 wherein the image transfer device is a printer, photocopier, or facsimile device.

4. The method of claim 1 wherein the image transfer medium is paper or plastic.

5. The method of claim 1 wherein the medium marking material is a visible material on the image transfer medium prior to operating the image transfer device.

6. The method of claim 5 wherein at least a portion of the visible material is legible to an operator of the image transfer device prior to operating the image transfer device.

7. The method of claim 5 wherein the medium marking material is rendered indistinguishable from the image transfer medium at some point in time during or after operation of the image transfer device responsive to the image transfer medium.

8. The method of claim 7 wherein heat within the image transfer device causes the medium marking material to become indistinguishable from the image transfer medium.

9. The method of claim 1 wherein the medium marking material is disposed on or as part of the image transfer medium in a coded manner for operating the image transfer device.

10. A method of controlling operations of a printer device through use of a temperature reactive marking material on a medium to be printed in the printer, the method comprising:

(a) marking the medium with the marking material;

(b) feeding the medium to the printer for printing per instructions identified by the marking material on the medium;

(c) sensing the marking material on the medium and producing a marking signal;

(d) operating the printer responsive to the marking signal; and

,

(e) causing the marking material to become non visible on the medium.

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

(a) means for sensing a medium marking material on an image transfer medium used in the image transfer device;

(b) means for producing a marking signal responsive to the sensed medium marking material; and

,

(c) means for operating the image transfer device responsive to the marking signal.

12. The system of claim 11 further including means for translating the marking signal to a command signal recognizable by the image transfer device for operating the image transfer device.

13. The system of claim 11 wherein the image transfer device is a printer, photocopier, or facsimile device.

14. The system of claim 11 wherein the image transfer medium is paper or plastic.

15. The system of claim 11 wherein the medium marking material is a visible material on the image transfer medium prior to operating the image transfer device.

16. The system of claim 15 wherein the medium marking material becomes non visible at some point in time during or after operation of the image transfer device responsive to the image transfer medium.
