Genuine OEM Oki MB491 Toners

The MB491 offers several black toner capacities and uses a separate image drum. Moving to a larger toner cartridge gives you more pages between changes, but it doesn't include a new drum or address a drum maintenance request.

Toner Buzz carries genuine OKI 44574701, 44574901 and 44917601 toner, along with the 44574301 drum. Choose 44574701 for lighter use, 44574901 for a longer run, or 44917601 for the largest page supply of the three.
