Hello, I ordered 19 November 2012, Canon cartridges CLI 521 Color Multipack I received on time, as always with Amazon. By cons, after receipt, and since I used my printer with new cartridges can be 2 or 3 times for a draw every time. This afternoon, I wanted to print an ID that you wonder, unfortunately, the cartridges that you delivered me not operate. When I raise the hood of my Canon MP 640 these cartridges are blinking, so HS So little used and so little time it seems abnormal. Client on your site for some time, I hope a new shipment from you. Kind regards.
