Genuine OEM Oki Microline 420 Toners

The Microline 420 uses a 42377801 black ribbon cartridge rather than toner. If you're keeping a spare ready, OKI's instructions say to leave it in its packaging until you need it.

Toner Buzz carries genuine OKI 42377801 black ribbons for the Microline 420 as individual cartridges. When installing one, leave the ribbon shield in place, as OKI directs.
