Certainly, the delivery was impeccable, but the replacement must be done too quickly. This is twice less than the number of pages announced. First, the Brother machine announces that the toner is low. Do not panic. We have our time. Finally comes the time to change mandatory. I have less than 5000 copies or impressions and I am in my 4th cartridge. It must be Brother who mocks some of the world announcing the printing possibilities twice higher than reality.
