How do I clear the message "Drum!"?

Description of Solution 200000040005

The message "Drum !" will typically appear on the LCD if the primary corona wires on the drum units need to be cleaned or if the toner cartridge and drum unit assembly is not installed correctly.


1.    Fully open the top cover by lifting up on the handle.



2.    Looking at the toner cartridge and drum assemblies, make sure the black handle of the drums are visible for all the assemblies.  If any of the assemblies are gray, not black, this means the toner cartridge was installed without the drum.  See image below.



-      If all the handles are black, go to STEP 3.


-      If any of the handles are gray, you are missing the drum unit(s).  The toner cartridges have to be installed into the drum units prior to installing the toners into the machine.  You need to purchase a new DR221CL for the color(s) missing a drum.


-      If you find your local retailer does not carry the specific supplies and accessories you are looking to buy, you can purchase them by calling our toll-free Accessory Line on 1-877-552-MALL (6255) or shop online at our website –


3.    Carefully remove all the drum unit and toner cartridge assemblies identified on the LCD.  Be sure to place the assembly (ies) on a clean, flat surface with a piece of disposable paper underneath in case of spilled or scattered toner.



4.    Clean the primary corona wire(s) inside the drum unit(s) by gently sliding the green tab from right to left and left to right several times.  Be sure to return the green tab to the home position on the left side before you put the drum/toner assembly back into the printer. If you do not return the green tab to the home position, it could result in a vertical stripe on printed pages.



5.    Reinstall the drum unit and toner cartridge assembly(ies) into the machine by sliding it into the correct slots.  Be sure to match the toner cartridge color to the same color label on the machine.



6.    Close the top cover of the machine. You will hear a loud click when the top cover is closed firmly.


7.    Confirm if the error message continues to appear. 


8.    If the message continues to appear, confirm if you are using genuine Brother drums and toners.

If the message "Drum!" persists, replace the Drum unit (DR221CL).
