Print showing dark marks on the edge of the paper. I have cleaned the drum and toner using the slider. I have cleaned the comartment where the toner and drum are in the printer but I am still getting black marks on the side of the paper. The toner was installed about 3 weeks ago and the drum was installed about 6 weeks ago. They are both high use versions.

My printer is low on yellow and magenta and is printing a stripe of each color on the papers edge.

On the drums for each colour there is a purple/blue/green slider for cleaning the corona wire. If there is a stripe of colour anywhere on the page going from top to bottom check these sliders. They need to be where the arrow on the slider meets the arrow on the drum casing.

As for low toner on the Yellow and Magent - Replace the cartridges.

Print copy is very light. Is there an adjustment?

Usually light prints on a Brother just mean a bad toner cartridge, but try these first:
  • Most Brother drum units have a slider that you push back and forth. It's probably blue plastic. Sliding that wipes dust off a charging wire in the drum unit, where cleanliness is essential to getting a clean, dark print.
  • While you have the drum & toner out, look inside the machine for short, shiny steel wires on the inside walls. Those wires contact metal in the drum unit to transfer the high voltages required to get toner onto the paper. Clean those wires and contacts with a little wire brush or even a pencil eraser. Chances are, you've been pulling out your toner/drum assembly while this problem has been bothering you, and that has probably cleaned all the contacts enough.
  • Look at the slot in the top of the drum unit where you can look in and see the drum. The laser shines down through that slot to draw the image on the drum that will eventually be your print. Look up into the top of the chamber where the drum-toner sits, and you'll find a skinny glass window. Gently wipe that clean. Any dust or toner there will lighten your print. Be careful not to knock any of the tiny, black levers that stick up into the bottom of the area. Those are paper sensors, and they have to be delicate, so they can be moved by the paper passing over them.
I expect that none of these will help, and you'll have to get a new toner cartridge. If the old cartridge is still new, take it back to the store along with print samples. Maybe even bring the printer so they can test their toner themselves. They might just swap it for a fresh one; it's worth a try.

When making copies one edge of the paper has three dark spots. Look as if they could possibly be roller marks? Something need cleaned? Thanks


probably right, remove your toner drum and clean it with tissue paper or smooth cloth, this dots happen when your roller drum has some spot on it due to ink powder and also slide the tiny button on the fuser kit to clean it.

Wen i print, there's a dark streak down the left edge of the paper. Hw do i solve this problem?

Hello, this one is fairly simple to diagnose, Change the toner cartridge, does the problem go away? if yes the toner is the problem. If the problem remains it would most likely be the fuser, in which case it would likely need servicing and the fuser replaced.

I just replaced the drum and the toner, now there is a dark streak down the middle of every page that prints, What is the problem?

the ink where it come out maybe dirty as it usually does when changing
go to the print operation and run a clean up system and see if the colours come up ok
this method may use a bit of your ink but if in business needs this has to be done and proves ok
if problem persists , than take the toner out and with a bit of alcohol wipe and a dry wioe afterwards, clean the outlet

Print problems with brother MFC-8860DN

Replace the drum. The drum is failing.
When you replace the drum open the front door of the machine where thr drum and toner is.
Hit the clear/back button. Press 1
That resets the drum count after you replaced the unit.

Good luck!

Black Lines

Do the black lines only show up when useing the adf???? Or do they show up on both the adf and the copyboard glass??? If it is only when using the adf...... The fix is easy.... you have to clean the smaller piece of glass that is to the left of the copyboard glass with windex or rubbing alchola. If it is with both you may need a new drum and blade or a new ufr... Good Luck
