Genuine OEM Samsung CLP-680 ND Toners
Samsung 506L toner is rated for more pages than 506S toner in each matching color. Both options fit the CLP-680ND, so the L cartridge is the choice for longer between toner changes, while S gives you a lower-capacity option.
Toner Buzz carries genuine Samsung 506S and 506L cartridges in black, cyan, magenta and yellow. Start with the color you need, then choose its capacity. If one color gets used up often, its 506L cartridge lets you print more pages before the next change without ordering every color together.
