This really helped to clean the printheads. He didn't completely erase one of the four. But then we tried even more extreme methods from the internet which didn't completely fix the situation either. So, still a positive review for this product. FYI, I learned it the hard way: flushing printheads and printing test patterns takes a lot of ink. So despite the fact that this product is a good deal. I went through a whole set of color and black cartridges. for $70 which I had to replace. So over $140 was spent on everything.
