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

firstly, just press the switch one time is ok instead of taking out cartridge to reset when the ink use up when  using on cx5500/cx7300/cx8300/c110/r290/rx690/r280/rx680/rx595/r285/rx585/c120/d120 etc. CISS

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original cartridge above the ciss cartridges when there is any updating on printers, that's to say the ciss won't be out of date which lower risks and benefits CISS distributers much
