Genuine OEM OKI MPS5501b Toners

The MPS5501b keeps its black toner and image drum separate. The 45460501 cartridge supplies toner for printing; the 45456301 drum is a different maintenance part, so a new toner cartridge doesn't also give you a new drum.

For fresh black toner, Toner Buzz carries genuine OKI 45460501 cartridges for this printer. The genuine 45456301 drum is a separate choice for drum maintenance, not another type of toner cartridge.
