With Brother laser products the toner and drum work independently – this is cheaper to run than those where the two units are combined. If one runs out, you don't have to replace both items simultaneously, substantially reducing waste, saving precious resources and your cash.But don't be tempted to cut corners by using cheap consumables, as this can mean poor results, and in extreme cases could invalidate the manufacturer's warranty. The manufacturer's original consumables will always be the best choice, as they have been designed to deliver the best performance from our machines.Why not do your bit for the environment and return your used toner and drum units to our award winning recycling factory in Wales.
