Connected 4 colors, 5 colors and 6 colors two-switch-chip, two advantages

For ep Stylus Photo R260/R380/R580/R280

firstly, just press one switch twice is ok instead of taking out cartridge to reset when the ink use up when  using on Epson  Stylus D78/DX4050/DX7000F/DX6050/DX6000/DX5000/DX4000/C79/CX3900/CX5500/CX5600/CX5000/

CX6000/CX7000/CX4900/CX5900/CX6900CF/R270/R390/RX590/R390/R265/R360/RX560/R285/

R260/R380/R580/R280/1390/1400/1410/C91/CX4300....CISS

secondly, put one original cartridge on the above of ciss cartridges when there is any updating on printers, that's to say the ciss won't be out of date which lower risks and benefits CISS distributers much
