Question about Brother MFC-7820N Printer
When I scan or make a copy the printout always shows a line from top to bottom 7 cm from the left of the page. When I print the problem doesn't exist. Problem exists 4 weeks. I changed the drum and the cartridge, I cleaned the glas surface but problem remains.
Clean the glass AGAIN. I had this issue for weeks. Drove me NUTTTTS! Because I to cleaned the glass. But guess what... not well enough. On your glass there is a tiny .. maybe the tiniest of tiny.....speck somewhere. that causes this line. Trust me I did everything you did and I just knew it was the drum or something. But it wasn't. Sure fire test. Have someone fax you something directly to the machine. (you need something that doesn't pass over the glass) If it prints out fine .. no line... there is a speck on your glass!!! And anything copied, faxed or scanned from your unit will have that line. Ofcourse you have already done half the test yourself if you print something from your computer and dont see the line. Because a print would not pass over the glass either.

First you need to determine if it's doing from both the top and the glass.
1-assuming you are using the feeder to fax,copy or scan (the part that automatically picks up the paper) it comes out with a streak. Make a copy putting the paper on the glass and look at the copy. Does it have the streak?
2-lift the top and look to the left there should be a small 1inch glass, this is where it makes the copies from the feeder, is there a dot or white out or is the glass dirty? that's your streak, the paper is moving to make the copy,so the dot now looks like a line as opposed to making a copy on the glass it just sits there so a dot will stay a dot.
2- Clean with water or alcohol.
