Genuine OEM Samsung ML-6510 ND Toners

The ML-6510ND keeps its MLT-D309S black-toner cartridge separate from the MLT-R309 imaging unit, or drum. The drum is rated to last longer, so you don't need to treat these two supplies as a set.

Toner Buzz carries genuine Samsung MLT-D309S toner and the MLT-R309 imaging unit separately. Order the D309S for a black-toner need, and the R309 when it's the drum that needs attention.
