They didn't work in my printer. At first they installed correctly, but all prints came out with streaks. In the end, my printer rejected them (said they were buggy and refused to print anything). I looked at the backs and the metal contact points weren't like my old ones. I ordered a different type from a different company. All contacts fitted and I had no problems. Colorettos don't work.
