I've always used original toner for our two Kyocera laser printers and always had top printing results. However, prices for alternative toners are dramatically cheaper. Ultimately, I am but then become weak - a fatal mistake. After less than half an cartridge of alternative toner was used up, the print image paled until it is completely illegible and had dropouts. The replacement of the cartridge against an alternative replacement cartridge did not improve. It looked temporarily out even so that the Enwicklereinheit was damaged by the alternative toner, which has thankfully not materialized.
My conclusion: I use only genuine toner a. For the quality of the original toner, there are five stars. A star I pull off due to unreasonably high prices of original toner.
