Genuine OEM Oki B420dn Toners

The OKI B420dn has three toner sizes: 43979101, the larger 43979201, and the largest 43979215. Its 43979001 image drum is a different supply and is not another toner capacity.

Toner Buzz carries genuine OKI toner across all three size choices, along with the 43979001 drum. Select toner according to how heavily you print, and use the drum option only for a drum-related printer message.
