Genuine OEM Oki B440 dn Toners

The OKI B440 dn offers three black toner sizes. The 43979101 cartridge is the smallest, 43979201 holds more toner, and 43979215 holds the most; the 43979001 image drum is a separate component.

Toner Buzz carries genuine OKI toner in all three sizes, plus the matching drum. Choose the toner capacity that fits your print volume, or select 43979001 when the printer specifically identifies its image drum.
