Abstract
The present invention relates to a process for remanufacturing an ink jet ink cartridge. Specifically, the process relates to remanufacturing ink jet ink cartridges having design features that are designed to prevent the refill or otherwise reuse of the ink cartridge. The design features may include, but be not limited to, a memory device for tracking information relating to the cartridge such that ink may be prevented from flowing from the cartridge when a measured value reaches a threshold value. The present invention relates to a process whereby the memory device is manipulated to allow ink to freely flow from the cartridge.
