Open the front cover and remove the drum and toner.

There should be a paperjam in the machine. It reads back cover open because the piece of paper is covering the sensor for the back cover.

To reset the drum message:
Open the front door
Press and hold down the white button for about 4 seconds. Once all 4 LEDs are lit, release the button.
Close the front cover. Make sure that the Drum LED is now off.

Hi there
With some Brother printers you can try this.

Access the internal maintenance mode by pressing the Menu/Set button, then press * 2 8 6 4 within 2 seconds. This should put you in the maintenance mode menu. Enter 80, and then scroll down with the arrow down (round) key. You'll find an entry listed as purge count. If number is over 6000, enter 2 7 8 3.

This will reset the purge count value. Then the printer will restart, hopefully without the annoying cannot clean message.


Some times this happens because of using cheap compatible ink cartridges if this is the case change the ink cartridges.

Please come back and just gave a vote, it will gave me some satisfaction to know am helping some one so I will keep on helping.

Back Door is open. Printer will not work. Keep


The black flap inside the rear door has a sensor flag mounted on it. The flag goes thru a hole on the side. If the spring is missing or broken or the flag is missing or broken, the error will persist.

Back door wont close


First Isolate whether it is the Side Door or their is a door on the rear make sure that isn't open.
What I would do is Physically open and re-close all doors again the tabs and sensor get sticky after awhile. If not you could have a BAD sensor door switch.

Remove the Toner Drum unit and look for a little blue tab. Slide it back and forth a couple of times to clean a corona wire and see if that helps.

Back cover open message


I had the same error message. I also tried every compartment... Here's ultimately what my problem/solution was...

I turned the printer around and fully opened the back cover. I found that one of my kids had somehow fed a small piece of paper/cardboard into the printer. When I opened the back cover all the way I could see that obstruction (which I hadn't seen before). Pulled it out, and the error message went away. Works fine now.
