I was very hopeful because a lot of ink came out when cleaning, but as you can see in comparison they are exactly the same. I didn't do it a second time as they recommended because I ordered a replacement. So I used it here because other people have said in the reviews that they need to clean it before it can be used properly. I've done a few cleans and super cleans in the print settings, as well as an enzymatic clean, and the post photo I'm showing was the best I got in the end. You can see there's a slight difference, but it still doesn't clean up well enough for the paper to be legible.
