Imaging apparatus and methods

1. A method of modifying an imaging cartridge detachably mountable to an imaging apparatus, the imaging cartridge comprising a cartridge chip, the method comprising:

detaching the cartridge chip from the imaging cartridge, the cartridge chip comprising a light emitting device adapted for emitting light in the visible spectrum; and

attaching a replacement cartridge chip to the imaging cartridge, the replacement cartridge chip comprising a light emitting device adapted for emitting light outside the visible spectrum.

2. The method of claim 1 wherein when the imaging cartridge is mounted in an imaging apparatus the light emitting device for emitting light in the visible spectrum emits visible light towards at least one of a photoreceptor of the imaging apparatus and a user to provide the user with information.

3. The method of claim 2 wherein the light emitting device adapted for emitting light outside the visible spectrum emits light outside the visible spectrum towards at least one of a photoreceptor of the imaging apparatus and a user, the light outside the visible spectrum is not visible to the user.

4. The method of claim 3 wherein the light emitted outside the visible spectrum is infrared light.

5. The method of claim 3 wherein the light emitted outside the visible spectrum is ultraviolet light.

6. A method for reusing an imaging cartridge detachably mountable to an imaging apparatus, the imaging cartridge having a chip, the method comprising:

removing a chip from an imaging cartridge, wherein the chip includes a light emitting device that when activated emits light in the visible spectrum; and

attaching a replacement chip on the imaging cartridge, wherein the replacement chip includes a light emitting device that when activated emits light outside the visible spectrum.

7. The method of claim 6 futher comprising:

mounting the imaging cartridge in an imaging apparatus, wherein when activated by the imaging apparatus the replacement chip emits light outside the visible spectrum towards at least one of a photoreceptor of the imaging apparatus and a user.

8. The method of claim 6 , wherein the emitted light can be detected by the photoreceptor and is not visible to the user.

9. The method of claim 6 , wherein the emitted light is infrared light.

10. The method of claim 6 , wherein the emitted light is ultraviolet light.

11. An imaging cartridge detachably mountable to an imaging apparatus, the imaging apparatus having at least one receptor for detecting light emitted from an imaging cartridge mounted therein and the receptor is designed to receive light in the visible spectrum, the imaging cartridge comprising:

an outer body defining a container for holding an imaging material therein;

a chip attached to the outer body, wherein the chip includes a controller having a memory unit and a light emitting device that when activated emits light outside the visible spectrum; and

an electrical contact disposed on the outer body, wherein when the imaging cartridge is mounted in an imaging apparatus the electrical contact provides communication between the chip and the imaging apparatus, wherein the imaging apparatus sends communication signals to the imaging cartridge and the controller activates the light emitting device in response to the communication signals causing the light emitting device to emit light that is outside the visible spectrum.

12. The imaging cartridge of claim 11 , wherein the imaging material is a liquid material.

13. The imaging cartridge of claim 11 further comprising an installation handle on the outer body, wherein the chip is attached to outer body on the installation via an adhesive material.

14. The imaging cartridge of claim 11 , wherein the imaging device includes a receptor for detecting light emitted from the light emitting device and the imaging device determines that the light emitting device is activated when the receptor detects light emitted from the light emitting device.
