Genuine OEM Kyocera FS-3140MFP plus Toners
The FS-3140MFP plus uses TK-352 for black toner and DV-352 for the black developer. Because both end in 352, the letters at the beginning are essential; MK-350 and DK-320 identify the kit and drum.
Toner Buzz carries these genuine Kyocera toner and maintenance choices. Read the component name and prefix in the printer message before comparing the rest of the code, especially when choosing between TK-352 and DV-352.
