Genuine OEM Oki MB491+LP Toners

The MB491+LP uses a separate black image drum, so a toner order and a drum order address different needs. Even the larger toner cartridge supplies toner only; use the printer's supply message to decide whether it's time for toner or drum maintenance.

Toner Buzz carries genuine OKI 44574701, 44574901 and 44917601 black toner, along with the 44574301 drum. Choose 44917601 for the longest page supply among those toner options, or a smaller cartridge for lighter use.
