Genuine OEM Oki Microline 420 black Toners

The Microline 420's black printing supply is the 42377801 ribbon, not a toner cartridge. An unused ribbon should stay in its packaging until needed, so keep a spare sealed until it's time to install it.

Toner Buzz carries genuine OKI 42377801 black ribbon cartridges for the Microline 420, supplied individually. Keep the ribbon shield attached during installation; OKI's guide says not to remove it.
