Question about Brother MFC-7820N Printer
Just fixed the same problem. My solution was as follows: When you open the back cover there is another plastic flap/cover inside that drops. Across this 2nd cover there is a plastic rod running parallel with a plastic finger that sticks up perpendicular to the rod which I believe guides the paper into the roller.
On my machine this rod came out of line, placing it about a quarter inch to the left which affected the sensor and the guide. If you look closely, you will notice a small groove on the rod that needs to be in a specfic slot on the 2nd cover. Good luck

Open the front cover and remove the drum and toner(cartridge) 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.

My machine is not picking up paper , every time i have to take the paper out and fix it so it prints one page and again give me message that no paper fed.

There is a clip at the right side if you open the rear cover.. check if that came off as that is where the sensor is.. make sure when you pull out the paper, you didn't drag out the sensor actuator... else you will need to find way to put it back..
