Abstract

A consumable having a memory device for storing information such as usage information to be used by a the original manufacturer or re-manufacturer. The memory device can also be used to provided software updates or patches for the microcomputers within an image forming or other office automation device.

Claims

1. An image forming device which comprises:

a housing;

a print engine residing within the housing

a printer controller electrically connected to the print engine;

a consumable having a nonvolatile memory device in electronic communication with the printer controller; and

a communication channel connected to the printer controller and operatively connectable to a host device to obtain information therefrom and to store received information in the memory device.

2. The image forming device of claim 1 wherein the printer controller is configured to detect insertion of a new consumable into the image forming device and store data from the host device in the nonvolatile memory device.

3. The image forming device of claim 1 wherein the printer controller is configured to detect insertion of a new consumable into the image forming device and store data from the host device in the nonvolatile memory device and is configured to detect the end of life of the consumable and store information in the nonvolatile memory device related to the end of the consumables life.

4. The image forming device of claim 3 wherein the nonvolatile memory device includes programming instructions to update the functionality of the image forming device.

5. The image forming device of claim 2 wherein the nonvolatile memory device includes programming instructions to update the functionality of the image forming device.

6. The image forming device of claim 1 wherein the nonvolatile memory device includes programming instructions to update the functionality of the image forming device.

7. A consumable for image forming devices which comprises:

a consumable housing; and

a nonvolatile memory device attached to the consumable housing and configured to communicate electronically with the image forming device and to store data received from a connected host device.

8. The consumable of claim 7 wherein the nonvolatile memory device includes programming instructions to update the functionality of the image forming device.

9. A toner cartridge for image forming devices which comprises:

a housing; and

a memory device attached thereto configured to communicate electronically with the image forming device and to store data received from a connected host device.

10. The toner cartridge of claim 9 wherein the nonvolatile memory device includes programming instructions to update the functionality of the image forming device.
