Mfc 7820n prints weird black line down side of page

Our printer has begun printing a weird stripe down the right edge of all papers during all functions. It almost looks like tabs from a file folder, but then also has a little point in it also. I think it must be printing some component inside the printer. Is there a way to calibrate it or somethin?

How do I use manual feed on the brother mfc 7820N printer/fax/copier?


The manual feed slot located in the front of the machine above the paper tray.
  1. Slide the gray paper guides to fit the size of the paper
  2. Using both hands put the paper (side to be printed, face up) in the manual feed slot until you feel the front edge of the paper touch the paper feed roller. Let go of the paper when you feel the Brother machine feed the paper in a short distance.
  3. You must then go to the application that you want to print to the paper and use that application's paper settings to set the paper size, orientation, font, style, etc
  4. Good luck trying...

Vertical black line in scan document not in copies through document feeder


Lift the lid and to the left of the main glass is a smaller glass; that is what scans during the feeding process. Make sure that it is completely clean; even a speck of dust can cause a line to appear. I took a lens wipe and cleaned mine and my line was gone.

Print Problem - vertical lines


If the problem only occurs when using the document feeder, the problem is not usually caused by the drum. When using the document feeder, try to notice where the scanner (the light assembly under your scan glass)stops just before the paper is being fed. Some multifunction machines have a small piece of glass that is separate from the large scan glass and the scanner assembly stays parked underneith it as the original is being fed over it. Most likely there is something on the glass where the scanner parks as originals are being fed thru the feeder. When putting your original on the large scan glass to copy, the mark on the glass will only show as a spot, but will show as a vertical line thru the whole copy when using the feeder.

Brother MFC-7820N Laser Printer


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.
