The MFC-8370DN takes TN-620 black toner. TN-650 is the high-yield option for heavier printing, and DR-620 is a separate drum rather than another toner cartridge.
Toner Buzz carries genuine Brother TN-620 and TN-650 toner alongside the DR-620 drum. Choose toner by capacity when the cartridge is low, or use DR-620 when the printer specifically calls for a new drum.
