Genuine OEM Brother HL-L6400DWT Toners

For the HL-L6400DWT, a TN850 twin pack and a TN890 cartridge solve different needs. The twin pack gives you another TN850 to keep as a spare; TN890 puts more printing capacity into one cartridge, so you change toner less often.

Toner Buzz carries genuine Brother TN820 standard, TN850 high-yield and TN890 ultra-high-yield black toner, plus the TN850 twin pack. The DR890 drum is a separate part, so a toner order doesn't include a new drum.
