SOURCE: Brother MFC 7820N error message

If you open the back cover (depress the release button on the top right) If you lift it up look for two black anchors that grab the base when you close the lid. I have one that has a broken tab on the left side, which happens to be the same side as the cover closed switch. If the top is not closed all the way the rollers do not line up and the cover switch is not depressed to let normal operation. Also, if the switch arm is busted (case colored plastic push pin protruding from the cover) it will not make contact with the switch when closed. Try closing the cover and push down on left side of the fax. Does the error go away? If not, the actuator arm or the switch are bad.

SOURCE: Bad Scan Quality Using Brother MFC-7820N Document Feeder

Look to the left side of the flatbed glass for a thin strip of glass by itself. When you scan from the glass, the document stays put and the sensor moves across the document. When you scan from the feeder, the sensor stays in that glass strip and the document moves across the sensor. See what I mean? I would check the small feeder glass for dirt or scratches from staples or other flotsam. Also not a bad idea to blow out the feeder path with some compressed air to ensure the documents is handled smoothly. Hope this helps!

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.

How do you remoce the drum to clear a paper jam on


Lift the top, remove the toner and open the access panel in the back, remove the printer tray. You should be able to see the full path the printer takes from start to finish. Rarely do you need to take anything else apart. If these areas are clear as the printer will attempt to clear jams when you start it up.

The 7820N prints double-sided manually using the drivers. From Windows, select File / Print. On the pop-up window, click on Preferences, select the Advanced tab, click on the A/B pages icon, and select Manual Duplex. "OK" your way out. When you print, you'll first confirm to print one side of all pages. Then follow the instructions that appear.
