Abstract

A method for storing data in an electrical storage device associated with a printing component of an ink-jet printing system. The electrical storage device is responsive to printing system control signals for transferring information between the printing component and the ink-jet printing system. The electrical storage device includes a write once portion, a non-protected portion, and a protected portion. The write once portion or the protected portion contain information indicative of a refill ink in the printing component. Installation of the printing component into the printing system enables the printing system to alter information in the write once portion or the protected portion to indicate that the refill ink in the printing component has been used.

Claims

1. A method for storing data in an electrical storage device, the electrical storage device associated with a printing component of an ink-jet printing system, the electrical storage device responsive to printing system control signals for transferring information between the printing component and the ink-jet printing system, the method comprising:

providing a write once, a protected and a non-protected electrical storage portion of the electrical storage device; and

selling the protected electrical storage portion to a state indicative of a refill ink in the printing component, wherein installation of the printing component associated with the electrical storage device into the printing system enables the printing system to set the protected electrical storage portion to a state indicative that the refill ink in the printing component has been used.

2. The method for storing data in an electrical storage device of claim 1, wherein setting the protected electrical storage portion to a state indicative of a refill ink in the printing component comprises setting the protected electrical storage portion to a non-protected state.

3. The method for storing data in an electrical storage device of claim 2, wherein the protected electrical storage portion in the non-protected state is responsive to write control signals for storing information provided to the protected electrical storage portion.

4. The method for storing data in an electrical storage device of claim 1, further comprising storing information indicative of a refill ink in the write once electrical storage portion of the electrical storage device.

5. The method for storing data in an electrical storage device of claim 1, wherein the printing component associated with the electrical storage device is an ink container for providing ink to the ink-jet printing system, the ink container depleted of an initial ink.

6. A method for storing data in an electrical storage device, the electrical storage device associated with a printing component of an ink-jet printing system, the electrical storage device responsive to printing system control signals for transferring information between the printing component and the ink-jet printing system, the method comprising:

providing a write once, a protected and a non-protected electrical storage portion of the electrical storage device; and

storing information in the write once electrical storage portion indicative of a refill ink in the printing component, wherein installation of the printing component associated with the electrical storage device into the printing system enables the printing system to alter the information in the write once electrical storage portion to indicate that the refill ink in the printing component has been used.

7. The method for storing data in an electrical storage device of claim 6, wherein the write once electrical storage portion is responsive to only a first occurrence of write control signals from the ink-jet printing system, and wherein the write once electrical storage portion is responsive to read control signals for transferring information stored in the write once electrical storage portion to the ink-jet printing system.

8. The method for storing data in an electrical storage device of claim 6, wherein the printing component associated with the electrical storage device is a replaceable ink container depleted of an initial ink, and wherein storing information in the write once electrical storage portion of the electrical storage device indicative of a refill ink in the printing component comprises storing information indicative of a full refill ink quantity in the replaceable ink container.

9. The method for storing data in an electrical storage device of claim 6, further comprising setting the protected electrical storage portion to a state indicative of a refill ink in the printing component.

10. A method for storing data in an electrical storage device, the electrical storage device associated with a replaceable printing component of an ink-jet printing system, the electrical storage device responsive to printing system control signals for transferring information between the printing component and the ink-jet printing system, the method comprising:

providing a write once, a protected and a non-protected electrical storage portion of the electrical storage device; and

setting the protected electrical storage portion to a non-protected state, wherein installation of the replaceable printing component associated with the electrical storage device into the printing system enables the printing system to store printing component information in the protected electrical storage portion.

11. The method for storing data in an electrical storage device of claim 10, further comprising storing information in the write once electrical storage portion of the electrical storage device.

12. The method for storing data in an electrical storage device of claim 11, wherein the replaceable printing component associated with the electrical storage device is a replaceable ink container containing a quantity of ink, and wherein storing information in the write once electrical storage portion of the electrical storage device comprises storing ink quantity information.

13. The method for storing data in an electrical storage device of claim 12, wherein storing ink quantity information in the write once electrical storage portion of the electrical storage device comprises storing ink quantity information indicative of a full ink quantity in the replaceable ink container.
