Each Brother TN-3437 Toner is rigorously print tested to ensure that every customer receives the quality and performance they expect. Most Brother laser printers and all-in-ones have a separate drum unit and toner cartridge, which are replaced individually. This design helps reduce waste and is more economical than a single-piece cartridge design.
Brother's Chemically Produced Toner (CPT) is specially formulated to maximise print quality and performance. You can expect high quality prints every time you print using genuine Brother TN-3437 Toner cartridges.
