Abstract

Methods and systems using printhead tank memory to determine printhead tank configuration are provided in accordance with embodiments of the invention. One example embodiment of the invention may include a printhead ink tank. The printhead ink tank may include a memory tag readable by a printer memory tag reader in communication with a printer controller. The memory tag may further include ink tank configuration instructions that include at least one of an ink tank configuration identifier or at least one ink tank location identifier. The ink tank configuration instructions can cause the printer controller to perform at least one memory operation associated with the memory tag.

Claims

1. An ink tank, comprising:

a housing for holding ink; and

a memory tag associated with the housing;

wherein data stored in the memory tag includes ink tank configuration instructions, the ink tank configuration instructions identifying a total number of ink wells that are anticipated for installation in a printing system when the ink tank is included as one of the installation tanks.

4. The ink tank of claim 1, wherein the ink tank configuration instructions identifies the ink wells as a number of N ink wells in either (a) a single ink tank configuration, (b) in a dual ink tank configuration, or (c) a four tank configuration, where N is greater or equal to two.

5. The ink tank of claim 1, wherein:

the memory tag is configured to be readable by a controller associated with a printer; and

when the ink tank configuration instructions identify the ink tank as a sole ink tank in a single ink tank configuration, the controller responds by terminating memory operations.

6. The ink tank of claim 1, wherein the ink tank is a first ink tank and the memory tag is a first memory tag, and wherein further:

the first memory tag is configured to be readable by a controller associated with a printer; and

when the ink tank configuration instructions stored in the first memory tag of the first ink tank identify the first ink tank as one of two ink tanks in a dual ink tank system, the controller responds by performing a first memory operation associated with the first tank and a second memory operation associated with the second tank.

7. The ink tank of claim 6, wherein the ink tank configuration instructions cause the controller to terminate the memory operations subsequent to performing the first and the second memory operations.

8. The ink tank of claim 1, wherein the ink tank is a first ink tank and the memory tag is a first memory tag, and wherein:

the first memory tag is configured to be readable by a controller associated with a printer; and

when the ink tank configuration instructions stored in the first memory tag of the first ink tank identify the first ink tank as one of N ink tanks in a N-ink tank system, the controller responds by performing a first memory operation associated with the first tank and successive memory operations associated with each of the next (N-1) memory tags, where N represents any number greater than two.

9. The ink tank of claim 1, wherein:

the memory tag is configured to be readable by a controller associated with a printer that can be operated in a plurality of modes depending on how many ink tanks are installed; and

wherein further the ink tank configuration instructions identify to the controller a number of ink tanks that will be installed in the printer and an associated mode of operation.

10. The ink tank of claim 1, wherein the ink tank configuration instructions identifies a location of at least one other ink tank in a printer having a plurality of installed ink tanks.

11. The ink tank of claim 1, wherein the memory tag is a radio frequency identification memory tag that communicates with a memory tag reader via a radio frequency communications protocol.

2. An ink tank, comprising:

a housing;

one or more ink wells for holding varieties of ink in said housing; and

a memory connected to the housing having stored bits, at least one bit configured for identifying to a printer controller a number of said ink wells in all ink tanks anticipated for installation in a printing system when the ink tank is included as one of the installation tanks.

3. An ink tank, comprising:

a housing with one or more ink wells for holding varieties of ink; and

a memory connected to the housing configured to be read by a printer controller in a printing system, the memory having stored bits identifying to a printer controller a number of said ink wells so the printer controller can terminate memory operations after performing memory operations only for a number of N ink tanks actually installed in the printing system.
