Genuine OEM Oki B4550 Toners

The OKI B4550 offers 43502301 standard-yield toner and 43502001 high-yield toner for its single black position. The separate 43501901 image drum is needed only when the printer identifies the drum.

Genuine OKI toner in both capacity levels and the matching image drum are grouped here at Toner Buzz. Choose a toner cartridge based on how much you print, or the drum when that specific maintenance notice appears.
