I have installed the toner a few weeks ago and I am very satisfied with the print quality. In my opinion, he is the original toner because in every way. The cartridge fitted properly into the slot and snapped immediately and fed a. It crumbled out no toner or so, everything went well. The printer detects a new cartridge immediately after being switched, again no problems. Should the positive print image to the end of the cartridge does not deteriorate and the pressure range to be respected as promised then is a renewed buying anything contrary!
