Genuine OEM OKI B731dn Toners

The B731dn has three black toner capacities to suit different printing workloads. Choosing a larger cartridge gives you more pages before the next toner change, so capacity is worth considering if the printer gets frequent use.

Toner Buzz carries genuine OKI 45488801, 45488901 and 45439001 black toner. The 45488801 suits lighter printing, 45488901 provides a longer run, and 45439001 gives you the most pages per cartridge of these three choices.
