Method and apparatus for spoofing imaging devices
Techniques for spoofing an imaging device adapted for reading data from an electrical storage device to determine a volume of ink in an ink container include providing a replacement electrical storage device for use with the ink container, the replacement electrical storage device comprising memory locations; and responding, by the replacement electrical storage device, to reads of memory locations of the replacement electrical storage device by returning data to the imaging device which causes the imaging device to calculate an inaccurate initial volume of ink stored in the ink container.
1. A system for spoofing an imaging device adapted for reading data from an electrical storage device to determine a volume of ink in an ink container, the system comprising:
a replacement electrical storage device for use with the ink container, the replacement electrical storage device comprising memory locations,
wherein the replacement electrical storage device responds to reads of memory locations of the replacement electrical storage device by returning inaccurate data to the imaging device which causes the imaging device to calculate an inaccurate initial volume of ink stored in the ink container.
2. The system of claim 1 wherein the data returned to the imaging device from the replacement electrical storage device comprises:
an ink container volume parameter specifying an ink volume range of the ink container; and
an inaccurate fill proportion parameter in the replacement electrical storage device not indicative of a fill proportion for the selected ink volume range.
3. The system of claim 2 wherein the inaccurate fill proportion parameter is greater than an accurate fill proportion parameter, and wherein the inaccurate fill proportion parameter causes the imaging device to calculate an inaccurate volume of ink stored in the ink container greater than an actual volume of ink stored in the ink container.
4. The system of claim 2 wherein the inaccurate fill proportion parameter is less than an accurate fill proportion parameter, and wherein the inaccurate fill proportion parameter causes the imaging device to calculate an inaccurate volume of ink stored in the ink container less than an actual volume of ink stored in the ink container.
5. The system of claim 2 wherein the calculation of the inaccurate initial volume of ink stored in the ink container causes the imaging device to calculate an inaccurate amount of ink remaining through at least a portion of the use of the ink container.
6. The system of claim 2 wherein the ink container volume parameter specifies an inaccurate ink volume range of the ink container.
7. A system of spoofing an imaging device adapted for reading data from an electrical storage device to determine a volume of ink in an ink container, the system comprising:
a replacement electrical storage device for use with the ink container, the replacement electrical storage device comprising memory locations,
wherein the replacement electrical storage device responds to reads of memory locations of the replacement electrical storage device by returning at least partially inaccurate data to the imaging device, and
wherein the partially inaccurate data causes the imaging device to calculate an incorrect initial volume of ink stored in the ink container.
8. A system of spoofing an imaging device adapted for reading data from an electrical storage device to determine a volume of ink in an ink container, the system comprising:
a replacement electrical storage device for use with the ink container, the replacement electrical storage device comprising memory locations,
wherein the replacement electrical storage device responds to reads of memory locations of the replacement electrical storage device by returning an inaccurate fill proportion parameter to the imaging device, and wherein the inaccurate fill proportion parameter causes the imaging device to calculate an incorrect volume of ink stored in the ink container.
