My Canon Pixma MX 870 just died....Rather than taking it to a repair outlet, I decided to replace it. I have a total of 17 remanufactured cartridges that were ordered from Inkjet Superstore for the Pixma MX870. There is 1 large black, 6 regular sized black, 4 yellow, 3 cyan, and 3 magenta. These cartridges are in the original packaging from Inkjet Superstore, and these cartridges have worked very well in the MX 870. I will sell them if someone is interested...
