Genuine OEM Brother HL-5350DNLT Toners
For the HL-5350DNLT, TN-620 is the standard-yield black toner and TN-650 is the high-yield option. DR620 is the drum, so it is changed for a different reason than either toner cartridge.
Toner Buzz carries both genuine Brother toner capacities and the DR620 drum for this printer. Pick TN-620 or TN-650 based on how often you print, and use DR620 only when the drum is due.
