Printing okay on left side but gets darker and blurrier towards right side of lines

I just changed the black drum in my printer. Now it prints okay on the left side of the page but the letters start getting darker and start to bleed toward the right side.

Please help.

    I have the identical problem. I changed the black drum a few days ago, and now the printing is darker (and blurrier) on the right half of the page. It looks like it is printing in bold, or perhaps in another font, on half of the page.

Remove the toner cartridge and drum assembly together. Gently rock the assembly from end to end, as when installing a new toner cartridge. Then put the assembly back in place. This procedure worked for me. I'm guessing that I must have laid the toner and/or drum on its side, or perhaps upside down, when I was replacing the drum, and this was responsible for the problem.

My Brother MFC-7420 Printer always prints black lines and splotches down the left side of my paper. This happens whether I'm scanning or printing from my PC. When I looked at my drum, it appears a


If you are seeing vertical streaks/black lines your primary corona wire is dirty and or the fax scanner may be dirty.
1)To clean the corona wire you take the drum unit and toner cartridge and place it on disposable paper to avoid spilling.
2) Clean the primary corona wire inside the drum unit by sliding the blue tab from right to left several times.
3) Return the blue tab and snap it into the home position.
4) Reinstall the drum unit and toner cartridge.
5) Close the front cover.
Caution: if you do not return the blue tab to the home position it may repeat the black lines.

Copies have black roller marks on the right side of each page, getting darker each time. I can print a single sheet, wait, it print again, wait~roller lines aren't as bad, but still present


I could be wrong, but I think it's in the toner cartridge. The drum - the roller that the image is formed on - has a soft, plastic blade rubbing against it to clean off excess toner after each print. If a clump of toner gets stuck under the blade, a line is printed down the page where that part of the drum isn't cleaned as well. Between prints, the drum keeps turning, and may be able to clean itself better than in a single revolution. It's a theory, anyway.
Pull out your toner cartridge and look at the drum to see if there's a black line around it at one end. You can't get to the cleaning blade without risking ruining the drum and the cartridge; the cure is just to get a new cartridge. If yours is fairly new, take it back to the store that sold it to you, along with a print sample. They might exchange it.
If the drum doesn't have a line around it, you can test it by deliberately jamming the machine. It's scary, but if you've unjammed jams before, you can do it again. Start a print job, then kill the power when you think the page is right in the middle of the printer. Open the printer and remove the toner cartridge. Look for that black line on the page before it reaches the drum, between the drum and the fuser, and past the fuser. (The fuser is the pair of hot rollers that pinch the page tightly and melt the powdered image into the paper. Any part of the image that hasn't made it into the fuser is still powder and will rub off.)
If the line doesn't show up until after the hot rollers, then I was wrong about the toner cartridge, and you're looking at a fuser problem.

The right side of the printable portion of each doc prints light


You just need to remove the toner and reach in with a dry rag and wipe the little inch wide window that is above where the toner goes. This window gets covered with toner dust and makes prints lighter...It runs all the way from right to left above the toner and drum.

Hi there,

I believe there are 3 possible causes for this issue; toner drum, fuser or transfer roller - more than likely I would dismantle the printer and check for lines on the fuser. But just in case remove the toner and carefully release the flap to reveal the toner drum - if that is scored and the lines correspond to those on the print-out thats the cause.

Black Line on Rt side of every printed sheet!


Hi,
I don't know if this will help but I was getting smears on the right side of the paper where there was no printing. I came acrossed this and it worked for me. Open up the front cover and lift the top cover and remove the drum cartridge. Then with cartridge out remove the left and right screw on the side of the cartridge. This will give the drum belt room without hitting the cartridge case. The cartridges plastic was not formed well.
