I have resorted to this toner as with the original toner on the duration but is too expensive. In the first printing with this toner, I can not see any difference from the original toners from Samsung. Since it is refilled original toner cartridges, there should be no problems with recognition. The range is specified with 2500 sheets (at 5% coverage). Whether this is true, I can of course now in the first few pages too early to say. Since most printouts but have more than 5% coverage is one may not quite reach 2,500. But that's just a guess on my part and is sure to each individual printing behavior. If I have found the final reach, I will update this review.
