I have toner dust inside the compartment where the cartridges are installed. The cartridges don't seal tight and toner dust is "poofing" out. I clean when I change the cartridges but it is becoming more evident that it is leaking out because of dust inside my front cover near to the drum. Is this going to shorten the life of the drum? I know I am losing money because the dust is not only being used for printing. I only use Dell toner and purchase the high yield cartridges.
