Genuine OEM OKI C841dn Toners

The C841dn has a separate image drum for each toner color. That makes the supply type important: if the printer asks for a cyan drum, a cyan toner cartridge isn't the same item, even though both names contain the color.

Toner Buzz carries genuine OKI black, cyan, magenta and yellow toner and individual image drums in those same colors. Match a toner request to its toner cartridge, or choose the named color's drum when the printer calls for drum maintenance.
