Yes — the MFC 8120 uses a replaceable imaging drum: BRT DR510 (BRT DR-510).
On the MFC 8120, a "Toner" message can come from either the toner cartridge or the separate drum unit. First reseat the toner cartridge and power-cycle the printer for 30 seconds. If the warning is drum-related, reset the drum counter from the printer menu; when the drum is genuinely worn, install a new BRT DR510. For toner issues, a fresh BRT TN570 resolves it.
These quick tips apply to all laser printers. While your exact model may look slightly different, the steps are identical.
