Genuine Brother TN350 Black Toner Cartridge For DCP-7020, HL-2030 & lots more, that yields 2500 copies. This is a common cartridge that will fit many brother machines even older ones. One of the pictures lists model numbers that it fits. This is the correct cartridge for more machines than what’s on the box so if your calls for a TN – 350 cartridge, this is the correct one . I’m listing as open box but only one flap is open.
