The toner was relatively inexpensive (15, -) compared to the original toners from Samsung. On the 1st day I had made a few prints and the image was absolutely fine. On the 2nd day I had to print out a few forms, here a white stripe was then suddenly (about 0.5cm thick, vertical) exist - complaints / return form printed and first left lying one day. Then the next day I wanted to again make a few test prints to settle it when returning - at one time we went back without artifacts. In the next few days then everything was OK. Therefore, I have to keep him now yet. For the initial Macke between I forgive but then only 4 stars.
