Genuine OEM Oki B4400n Toners

The OKI B4400n uses 43502301 black toner and a separate 43501901 image drum. Since each component has its own service notice, a drum warning should not be handled with another toner cartridge.

Toner Buzz carries genuine OKI 43502301 toner and the matching 43501901 drum for this printer. Check whether the machine names toner or the drum, then select the corresponding part shown here.
