Hi.

EL, which wants to represent E6 is not a drum error code. EL (E6) means NVRAM error on main PCB.

If the error does not go away disconnecting power, then the main PCB (controller board) must be replaced.

Several forums cannot understand EL is E6 and point in the wrong direction. The full list of error codes is reported in service manual at pages 22-23. Service manual has been uploaded below:

I get a message to replace toner, i replaced and still get the messag


You may want to try the following steps:
  • Step 1 - First turn on your printer: Brother MFC 9840CDW.
  • Step 2 - Push the button on the front of the printer to open the cartridge cover or the front panel of the printer where you can access the toner cartridges. However, do not remove the toner cartridges (Brother TN-115).
  • Step 3 - Push the Clear/Back button and hold still to bring up a reset menu. There are 8 different toner functions ( two Black, two Cyan , two Magenta, and two Yellow).
  • Step 4 - For each of the eight functions in turn, push the O.K. button and then push it again to indicate 'Reset'. After a few seconds, it will say 'Accepted' and will then display a message that the cover is open.
  • Step 5 - Repeat the steps 3 and 4 for each of the other eight toner functions as needed.
  • Step 6 - Once your finished, close the front cover of your printer so the status bar will be reset to normal with no error message.
  • Also, you may want to clean the corona wires for each toner. Clean the corona wire inside the drum unit by gently sliding the green tab from left to right and right to left several times.

Drum error wont go away


This should be an easy one. Your Brother doesn't know it has a new drum until you tell it like this:
  1. Open the front, where the drum is.
  2. Touch the CLEAR button.
  3. The display will ask if you replaced the drum. I believe you touch 1 for "yes."
  4. Close the front door.

My brother MFC9840cdw has an error message that says, "drum error, slide the green tab on each of the colored drum units. Refer to the users guide". I have tried sliding the green sliders several times. I...


The guy that replied solved the problem. He rocks and I can't believe that brother does have a large posting on this issue. Sham on them:
ben2913 did the job "This is NOT the solution to this error code. The code is telling you that the Corona wire must be cleaned. Remove all 4 color drums. Look down into the tray that you removed them from and you will see 4 green tabs. Open the plastic cover that protects the corona wire and move the green tab back and forth several times. After you have done this with all 4, reinstall the drums, close the machine front and everything will work fine again."

You need to reset the drum counter.I'm not sure that working with your model but try it.
Try opening the front door cover and keep open. Then pressing clear, it should say replace drum, press 1 for yes, it should then say accepted, close cover and turn off.
