With Brother laser products the toner & drum work independently
- this is cheaper to run than those where the two units are combined. If one runs out, you dont have to replace both items simultaneously, substantially reducing waste, saving precious resources & your cash. But dont be tempted to cut corners by using cheap consumables, as this can mean poor results, & in extreme cases could invalidate the manufacturers warranty. The manufacturers original consumables will always be the best choice, as they have been designed to deliver the best performance from Brothers machines. Only by using original Brother consumables can you enjoy the ongoing improvements & technical changes that occur regularly throughout the life of your product.
