Just got a new canon pro9000 instead of putting oem carts in I put in a ciss. It worked ok for about a week and the lights on the printer cart went out so I placed the oem canon carts in they worked but the ink monitor says they are full when empty. Now when I try to replace a cart it wont except it no light on for the cart. Put the original cart in and the light is back on. Got generic carts and put those in and the light goes on but it does a head clean then does not recognise generic carts
