Kopykake Kolor Kartridges must use this technology in order for our Kolor Kartridges to work with Epson printers.Epson Printer Technology uses a microchip on each color tank which keeps track of the number of prints each tank has made to estimate how much ink is left.

Sometimes these microchips register a tank as empty when there is still ink/food coloring in them. The chip resetter resets the print tally on the microchips to zero so that you can continue printing if there is still ink/food coloring left in the tank. You only need to purchase the chip resetter once as it will work on all of your Epson tanks over and over again.
