The printer of the original cartridge prices excessively expensive when soon cartridge refill, renovation works a lot in technical service began to be made even just engaged in this business there are places many manufacturers this situation to prevent various measures took eposo in one of these refill cartridges with the printer operation so that a chip is used but these obstacles were overcome in a short time with some of the programs installed on the computer printer models are deceived resetleniyor with some additional circuitry of the chip.
Built on PIC12F629 chip, EPSON cartridge chip reset circuit modules that appear in the image below is used to working with 3-volt circuit has a simple structure hex may install and use the software to the microcontroller.
VDD, SHT, SDT, CLK, RESET, DATA, GND connections do hold circuit is open until 5 seconds after the reset operation will take place is called
