Abstract

A method of setting an address of a component that includes determining a characterization value associated with a consumable, calculating a number of address change operations based upon the characterization value, and setting a last address generated from the number of address change operations as the new address of the component, wherein the characterization value is determined based upon a usage of the consumable.

Claims (27)

1. Component circuitry, comprising:

an interface for coupling to a master; and

a dynamic address generator coupled to the interface, the dynamic address generator selectively generating component addresses, wherein substantially immediately following an event, the component circuitry performs in succession a plurality of sets of operations, each set of operations comprising receiving, by the interface, an address change request from the master and generating a new component address by the dynamic address generator in response, a last one of the new component addresses generated being available as the component address for the component circuitry in one or more subsequent communications with the master, the event comprising at least one of the component circuitry being coupled to the master, the component circuitry initially receiving power and the component circuitry being reset.

2. The component circuitry of claim 1 , wherein each set of operations further comprises sending at least one acknowledgement to the master by the interface.

3. The component circuitry of claim 1 , wherein the component circuitry is connectable to a tank containing toner or ink.

4. The component circuitry of claim 1 , wherein the component circuitry performs in immediate succession the plurality of sets of operations substantially immediately following the event.

5. The component circuitry of claim 1 , wherein the component circuitry performs in succession the plurality of sets of operations substantially immediately following each occurrence of the event.

6. The component circuitry of claim 1 , wherein a number of the plurality of sets of operations is based on an ink or toner level within a component to which the component circuitry is associated.

7. The component circuitry of claim 6 , wherein the number of the plurality of sets of operations is a number between a value corresponding to the ink or toner level and a predetermined number.

8. The component circuitry of claim 1 , wherein the component circuitry is connected to a tank containing toner or ink.

9. A consumable device, comprising:

a reservoir containing toner or ink; and

circuitry, comprising an interface for coupling to a master and a dynamic address generator coupled to the interface, the dynamic address generator for generating component addresses, wherein following an event, the circuitry performs in succession a plurality of sets of operations, each set of operations comprising receiving, by the interface, an address change request from the master and generating a new component address by the dynamic address generator in response, wherein a last one of the new component addresses generated is available as the component address for the circuitry in one or more subsequent communications to with the master, the event comprising at least one of the circuitry being coupled to the master, the circuitry initially receiving power and the circuitry being reset.

10. The consumable device of claim 9 , wherein each set of operations further comprises sending at least one acknowledgement to the master by the interface.

11. The consumable device of claim 9 , wherein the circuitry performs in succession the plurality of sets of operations substantially immediately following the event.

12. The consumable device of claim 9 , wherein the circuitry performs in succession the plurality of sets of operations substantially immediately following each occurrence of the event.

13. The consumable device of claim 9 , wherein a number of the plurality of sets of operations is based on a toner or ink level within the reservoir.

14. The consumable device of claim 13 , wherein number of the plurality of sets of operations is a number between a value corresponding to the toner or ink level and a predetermined number.

15. Component circuitry, comprising:

an interface circuit for communicatively coupling with a master; and

a dynamic address generator coupled to the interface circuit, the dynamic address generator selectively generating component addresses, wherein substantially immediately following an event, the interface circuit receives a plurality of address change requests from the master and, in response to each address change request received, the dynamic address generator generates a new component address and the interface circuit sends to the master at least one acknowledgement, each acknowledgement being sent before a next address change request of the plurality of address change requests is received by the interface circuit, a last one of the new component addresses generated being available by the component circuitry for one or more subsequent communications with the master, the event comprising at least one of the component circuitry being coupled to the master, the component circuitry initially receiving power and the component circuitry being reset.

16. The component circuitry of claim 15 , wherein the interface circuit receives the plurality of address change requests in succession.

17. The component circuitry of claim 15 , wherein the interface circuit receives the plurality of address change requests substantially immediately following each occurrence of the event.

18. The component circuitry of claim 15 , wherein the component circuitry is connectable to a tank containing toner or ink.

19. The component circuitry of claim 15 , wherein a number of the address change requests is based on an ink or toner level within a component to which the component circuitry is associated.

20. The component circuitry of claim 19 , wherein the number of the plurality of sets of operations is a number between a value corresponding to the ink or toner level and a predetermined number.

21. The component circuitry of claim 15 , wherein the interface circuit receives the plurality of address change request immediate succession.
