PROG_PRU3 : Chip reprogramming kit for Epson Photo RX640

This type of cartridge cannot be refilled.

We can offer you a reprogrammer to allow you to get full benefit from your cartridge. When your driver claims that the cartridge is empty, it still contains between 10 and 30% of its ink.

The reprogrammer allows you to reset the electronic « spy » circuit so that the you can use all the ink you have purchased.
