Toner Life End message on DCP-7040
If your cartridge has a lever on the left side near the rear, it needs to be reset, and there's a lever inside on the left that can stick and cause that error. You need to wiggle and pull that lever until it moves freely again.
My printer dcp 7040 keeps telling me DRUM ERROR
Sounds like you will need to replace the drum. You can order a drum kit from Grand and Toy or from the Brother website. There are also many other websites you can order a drum kit from. Once the Drum unit is replaced your printer will start working again.
For a cheaper solution you can always reset the drum kit making the printer believe that the drum kit was replaced. For this you might need the manual.
Hope this helps
