They don't work properly. the color is not true and it is not functioning properly. I utilize them for copies of sheets that need filing and that is alright, but they should work much better than they do. I run a Mission Center and this is a business expense. I think they are a terrific bargain, but they don't function properly and in true color as advertised. I think if I complained they would replace them, but I don't want to cause problems.
