How do I change the drum in my HL-5240

SOURCE: Brother HL 5240 printer: Drum light flashing

you need to replace drum cartridge, when you buy one back ,look new one then you'll find out where is the drum.

SOURCE: The drum light came on

I continued looking and found where someone else had the same problem. I opened the front cover, held down the go key for 10 seconds and closed the door. This reset something because it works now.

Thanks

Chances are if your drum requires cleaning, it could be faulty or at the end of its life. However if you must clean it DO NOT use any cleaning agents , chemicals or water. Use only the softest lint free cloth you can find and give it a gentle wipe over

Out with the old and in with the new, you remove the toner and drum together, remove the toner from the old drum by pressing the blue lever on the side, install the toner in the new drum, and re install in the printer. With the front door open press the go button til all lights flash and then close the door, the new drum is reset.
