The display panel on your Brother MFC-9940CN alerts you when the printer drum is near the end of its lifespan of approximately 17,000 pages. If you see "Drum End Soon" on your display panel, the printer drum is failing and you should replace it right away. Order drum kit DR-110CL from an office supply retailer and change the drum in just minutes at home.

Skill level:


  1. 1

    Turn off the power to the printer. Push the release button at the top of the front cover and fold the cover down. Let the printer rest for 30 minutes to cool to prevent injury from the drum.

  2. 2

    Grab the green handle on the front of the drum. Lift up slightly and pull the drum straight out. Push the grey locking lever on the left side of the drum unit straight up. Pull the drum out of the printer. Place the old drum on a large sheet of paper or other protected, flat surface.

  3. 3

    Remove the new drum unit from the packaging. Pull the protective tape off a new toner cartridge. Install the cartridge into the slots on the drum unit, pushing it into place until it clicks.

  4. 4

    Align the drum unit with the tracks on the inside of the printer body. Hold the grey locking lever up; slide the drum into the printer. Lower the grey lever. Slide the drum unit all the way into place until it locks. Close the front cover of the printer.

  5. 5

    Turn the power on to the printer. Push the "Menu" key, then press "8," followed by "4." Push the up or down arrow until "Drum" appears on the display. Press "OK." Push "1" to confirm that you want to reset the drum counter. Press the "Stop/Exit" button to force the drum counter reset.
