Genuine OEM Brother MFC-8680DN Toners
The MFC-8680DN takes TN-620 black toner. TN-650 is Brother's high-yield option. DR620 is a separate drum unit, so the toner codes answer a capacity choice while the DR code answers a maintenance need.
Genuine Brother TN-620 and TN-650 toner are joined by the DR620 drum at Toner Buzz. Use the printer's message to separate toner from drum service, then choose the toner capacity that fits your workload when a cartridge is needed.
