This is a ready-to-use cartridge, which has been remanufactured using our proprietary formulas and methods, and finally tested to be similar to the original cartridge in quality and page yield. The remanufacturing process for each cartridge differs, but in general every cartridge is remanufactured through our 3 step process:
1) CLEAN (old ink or toner is evacuated, print heads and other reusable components are cleaned using proprietary formulas and equipment)
2) REFILL (every cartridge is filled to the maximum capacity, and in the case of toner cartridges most moving parts such as drums, blades, rollers and other parts are replaced with new ones)
3) TEST (this is the final phase, and ensures that when we sell you a cartridge, that cartridge has been physically tested on a printer to ensure that it will perform to the quality expectations that you and we have)
