This is a chip resetter for these DTG Viper, Bullet or for these Epson models: 4000/4800/4880/7600/9600/7800/7880/9800/9880. If any DTG printer is based on these models then you can reset the cartridge chip to make the printer think that the cartridge is full of ink. It also works on the maintenance tank as well. Please note this is not an Epson product and that we do not have any relationship with Epson but do sell some genuine parts. We are also not affiliated with any other DTG company or manufacturing company.
