Yes — the MFC 8660DN uses a replaceable imaging drum: BRT DR520 (BRT DR-520).
Because the MFC 8660DN uses a two-part system — a toner cartridge plus a separate BRT DR520 drum unit — a "Toner" alert means checking both. Remove the drum-and-toner assembly, separate the two parts, and reseat each one. Toner low or unreadable? Replace BRT TN580. Drum life exhausted? Fit a new BRT DR520 and reset the drum counter.
These quick tips apply to all laser printers. While your exact model may look slightly different, the steps are identical.
