Back cover open close the back cover


If you turn the printer off and then back on with a paper jam in it you will get this error message instead of a paper jam message. To clear the paper jam from the back of the printer read the instructions from here: http://welcome.solutions.brother.com/BSC/public/us/us/en/faq/faq/000000/000600/000096/faq000696_001.html?reg=us&c=us&lang=en&prod=mfc7420_all&Cat=11

Brother MFC 7820N Toner life end with new toner


I found the following post on another site. It appears to work. If you want to reset your Brother MFC 7820N machine so you no longer have the error message: Toner End of Life, do the following:

1. Open the front cover of the 7820N, that is, the cover that allows you to pull out the toner and drum, but don't pull out the drum/toner.
2. Push the button: Options (located on the left of the control pad).
3. Type: *00 on the keypad.

The Brother MFC 7820N should be reset and the Toner End of Life message should disappear. WARNING: This may void your warranty and ultimately damage your machine if you are reusing or refilling your cartridges, but you should already know that. Hope this helps.

MFC 7820n 'close back door error'


Hello Daysinn,

The "back cover open" message is usually caused by a paper jam inside the printer.
Follow these steps to rectify the problem.

1. Unplug the power to the printer.
2. Open the back and front cover.
3. Remove the drum and toner, this may be difficult because it may be stuck; don't be afraid to pull hard, you wont break anything.
4. Check for any foreign objects, most likely a peice of paper.
5. Reinstall the drum and toner.
6. Make sure to close the front and back covers.
7. Turn the power back on.

If the message stays after all this, there may be a sensor not working.

Thanks,

Pat

I cannot get the BACK COVER OPEN message to GO AWAY. I tried to open the back black cover and check to see if there were any paper jam and i also opened the front cover and ejcted the ink toner and no...


There is a little cover there that has a sensor flag on it. It is most likely in a jammed position. If you are able to carefully take the cover out, you can bend it slightly, readjust the sensor flag, and reinstall it.

Thanks

MFC-7820N error message: back cover open; close back cover. The back cover is closed but error message will not go away and I can not print. Thank you.


There is a little black lever in the middle that needs to be re inserted properly. (like a little black stick in the middle.  Needs to slide to the left or right.   See more of this one the site.   It solved it for me.
