Original Brother toner is formulated to meet high quality resolution, grey scale and block colour, in line with Brother’s high design specification. 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. Toner particle size, shape and colour pigmentation all have a direct impact on the sharpness of the printed image. Brother's toner is formulated to exacting standards to ensure you receive high quality print resolution and reliability Why not do your bit for the environment and return your used toner and drum units to our award winning recycling factory in Wales.
