Genuine OEM Samsung ProXpress M3870 FW Toners

The M3870FW takes MLT-D203S or MLT-D203L black toner. The L cartridge is rated for more pages, giving you longer between toner changes. That extra capacity is useful if you go through toner quickly.

Toner Buzz carries genuine Samsung MLT-D203S and MLT-D203L cartridges individually. Choose D203L if you print frequently, or D203S when the lower capacity suits your printing. Check the S or L ending when ordering to select the cartridge you intended.
