The FS-3800 has two clearly different items to consider: TK-60 black toner for printing and the MK-62 maintenance kit for printer upkeep. The maintenance kit is not another toner option.
Toner Buzz carries genuine Kyocera TK-60 toner and the MK-62 kit for this model. Order TK-60 when you need toner; use MK-62 when the printer is due for the corresponding maintenance work.
