I ordered these cartridges and installed them about 4 weeks ago. Cartridges are almost empty. I am learning. My students printed. We printed less than 400 pages, about 1/4 of them in colour. My last printed paper, two minutes ago, has large white streaks where there is no ink at all. Overall, given the price per page, the cost was enormous.
