I just had to replace the waste ink tank on my Canon Pro-1000 printer. I love the printer but I weighed the empty vs full tanks and there was 250 grams of ink in the full one. That's roughly $188 of wasted ink. I have not replaced any carts since new except the CO and one of the blacks. I am nearing empty on many of them.
That means that for every $750 I spend on ink, roughly $188 is flushed down the toilet, so to speak. It never reaches the paper. This means that 25% of my money spent is just going to waste.
Who would like to file the class-action lawsuit? I will be the named plaintiff.
