Summary of EPSON CARTRIDGE RESET CIRCUIT PIC12F629
The article describes a PIC12F629-based EPSON cartridge reset circuit that lets refilled cartridges bypass printer chip protections. It's a simple 3V microcontroller module that interfaces with cartridge signals (VDD, SHT, SDT, CLK, RESET, DATA, GND) and holds the circuit open for up to 5 seconds after reset to enable printer acceptance. The device is intended for use with software tricks that reset printer counters on compatible EPSON models.
Parts used in the EPSON cartridge reset circuit PIC12F629:
- PIC12F629 microcontroller

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
