Genuine OEM Brother MFC-8660DN Toners

The MFC-8660DN takes TN-550 black toner. For high-yield capacity, the toner code is TN-580. The printer's DR520 drum is listed separately because it handles imaging rather than storing toner.

At Toner Buzz, the genuine Brother selection includes both toner cartridges and the DR520 drum. Match the printer's message to the part first, then choose toner capacity only when TN-550 or TN-580 is needed.
