Abstract

A cartridge including a carrier storing an authenticity verification code readable by a scan device other than a host device and an auto-destruct feature to render the authenticity verification code unreadable at installation.

First claim

The invention claimed is:

1. A cartridge to connect to a host device, the cartridge comprising:
an interconnect circuit to communicate with a host device;
a carrier other than the interconnect circuit to carry an authenticity verification code that is to be read in a contactless manner by a scan device other than the host device; and
an auto-destruct feature to, after installation of the cartridge into the host device, render the authenticity verification code unreadable,
wherein:
the cartridge comprises a housing that comprises a reservoir, toner dam, intermediate chamber, and a toner transfer assembly that define a toner travel path within the cartridge along which toner travels through the cartridge; and
the carrier is disposed along the toner travel path within the cartridge.

2. The cartridge of claim 1 , wherein the carrier is disposed so that toner particles conceal the authenticity verification code as the toner moves through the toner travel path after installation of the cartridge within the host device.

3. The cartridge of claim 1 , further comprising an adhesive provided on the carrier to adhere toner particles to the authenticity verification code.

4. The cartridge of claim 1 , further comprising a label provided on the carrier to absorb toner particles to conceal the authenticity verification code.

5. The cartridge of claim 1 , wherein the carrier is at least partly moved to clear the toner travel path such that toner may move through the toner travel path.

6. The cartridge of claim 1 , wherein:
the carrier is part of a toner dam to be pulled after installation for releasing toner, and
the auto-destruct feature is to damage the authenticity verification code when the toner dam is moved.

7. The cartridge of claim 6 , wherein:
the carrier comprises a contactless communication circuit storing the authenticity verification code, and
the auto-destruct feature comprises a second circuit to render the code unreadable after installation.

8. The cartridge of claim 1 , wherein the carrier is disposed downstream of the toner dam.

9. The cartridge of claim 1 , wherein the carrier is disposed within a housing of the cartridge which housing includes a reservoir, to be scanned from the outside of the housing.

10. The cartridge of claim 9 , wherein the housing comprises a window for detecting the authenticity verification code from the outside of the cartridge through the window.

11. A toner packaging assembly comprising:
a cartridge to connect to a host device, the cartridge comprising:
an interconnect circuit to communicate with a host device;
a carrier other than the interconnect circuit to carry an authenticity verification code that is to be read in a contactless manner by a scan device other than the host device; and
an auto-destruct feature to, after installation of the cartridge into the host device, render the authenticity verification code unreadable; and

a packaging at least partly surrounding the cartridge, the packaging comprising a window, the authenticity verification code being provided on the outside of the cartridge near the window so that the authenticity verification code is visible from the outside of the packaging through the window.

12. The assembly of claim 11 , wherein the authenticity verification code is stored on a contactless communication circuit.

13. A toner cartridge comprising:
a carrier for contactless data communication to carry an authenticity verification code to be read by a scan device other than a host device; and
an auto-destruct feature to, after installation of the cartridge into the host device, damage the authenticity verification code,
wherein:
the cartridge comprises a housing that comprises a reservoir, toner dam, intermediate chamber, and a toner transfer assembly that define a toner travel path within the cartridge along which toner travels through the cartridge; and
the carrier is disposed along the toner travel path within the cartridge.
