Genuine OEM Samsung ML-4512 ND Toners

The ML-4512ND's MLT-R307 is an imaging drum, not a cartridge of printing toner. It is separate from the MLT-D307 toner family, so a drum-maintenance need and a low-toner message call for different supplies.

Toner Buzz carries genuine Samsung MLT-D307S and MLT-D307L black toner, along with the MLT-R307 drum. Choose D307L for more pages between toner changes, or D307S for the lower-capacity cartridge. Keep the drum purchase separate and select it when that is the part your printer needs.
