Genuine OEM Brother MFC-8670DN Toners

For MFC-8670DN supplies, TN-550 covers one black toner capacity and high-yield TN-580 covers the other. DR520 is a separate drum unit with its own maintenance role.

The genuine Brother options at Toner Buzz include TN-550 and TN-580 toner plus the DR520 drum. Choose between the toner codes based on capacity, or move to the drum only when the printer identifies DR520 as the part requiring service.
