Look for a corona wire, close to the drum

  1. Clean the primary corona wire inside the drum unit by gently sliding the tab from right to left several times.
  2. Return the tab and snap it into the home position.

    On sending a fax the receiver copy has a black

    You must clean the glass strip that the origional passes over to be scanned. You may have White-Out or an Ink smuge on it. Another way to determine if it is your FAX is to put in an original and make a copy. If the line is on your copy than it is your scanner **** (glass).

    Black line down the center of the page on faxes

    I am assuming that you have clened the glass the problem therefore would be in the optics most likely a hair on a mirror. You can try opening up the case and cleaning them with a cotton ball and some alcohol, but unless you are handy you may not get it back together.

    Open the front of the fax machine. Then pull down the the tray that has the down arrow imprinted on it. Locate the glass strip towards the back, just behind the center roller. Use a cloth and rubbing alcohol to clean the glass and that should remove the black line.

    Black line about 1 1/2 inches wide down side of faxes or copies

    if your RECEIVED faxes look good, then leroyal is dead on. you will need a new CIS which stands for contact image sensor. if you have an authorized brother service center nearby, they may be able to do it for 100 to 150.00, depending on their pricing of course. if rec'd faxes are bad also, pull drum out and make sure the blue tab on top of drum is all the way to the right side, although that usually only leaves about a 1/2" black band.

    Line almost straight down center when receiving fax

    if you try a internal print such as a report does it go away? if so its more lucky the person sending you the fax.

    if you print a report and its on there i would check the ribbon and look for marks, also it could be a transfer problem causing these marks.

    Hope this gives you a starts

    Stripe on receiving fax Brother MFC 7820N

    I had the same problem, and I just fixed it.  It was a tiny little black dot which was stuck to the glass where the document feeder passes the paper to.  First you need to figure out where the line is on paper with respect to the paper, and just carefully run your finger on the glass to see if there is something on the glass.  I removed it, cleaned the glass, and anything which I run through the document feeder is now fine.  Hope this helps.
