Genuine OEM Oki MB400 Series Toners

For the MB400 series, 43979201 supports more printing between cartridge changes than 43979101. The larger black-toner capacity is useful if frequent printing means you often need to change the cartridge.

Toner Buzz carries genuine OKI black toner in both capacities for the MB400 series. The 43979201 and 43979101 are each sold as an individual cartridge, keeping the choice between capacities separate from the number of cartridges you order.
