Some Epson cartridges have a "Smart Chip". This is a small computer chip installed on the cartridge. It will not allow you to refill the cartridge without being reprogrammed.
The answer is our new universal chip resetter. It will reset a chip hundreds of times.
The resetter can be used on both black and color cartridges. The resetter is designed for use on OEM cartridges. It does NOT work on some generic cartridges.
