The toners are easily detected as a new toner from the printer. Toner dust is reloaded. It can be printed. The printed image in Black / White does not differ from original toner, the printing of photos with small nuances in color. If I did not have to compare the older term, I would be not noticed. Otherwise top as the expensive original!
I can only recommend this toner. Not the cheapest in the market, but certainly a very good alternative to the far too expensive original toners Epson.
