Apart from three chambers one is run out before the others so how can I stop wasting the other Inks?

I am asking this question for countless time. but I found that it is impossible bolt this issue. So i have bought new Canon Printer Ink Cartridges

You can always take you're printer cartridges to a refill station. The only time you have to watch it is if you have a Lexmark printer. Apparently Lexmark has done all sorts of things to make it hard for you to do anything but buy their product.

You could try using continuous ink supply system instead of original cartridges. You have 4 full ink tanks attached to your printer cartridges: cyan, magenta, yellow, black. Initially you purchase 120ml of ink insead of the usual 11ml. When one color runs out, you refill relevant tank, but you don't throw out the other colors you can use them up to the last drop!! Hope this helps
