SOURCE: Paper has black marks only on the edge

There are several issues that will cause a problem like that.
1, As X box mentioned is a problem with the drum. That is part of what is called the print cartridge or imaging unit. There is most likely a shutter or opening in the cartridge which you can shine a flash light at and see if the defect is visible. If so you will have to replace that cartridge. I would suspect that is the most likely issue.
2. There may be something in the paper path. A small piece of paper riped off in it, something else, a piece of tape, label, etc may have made it into the machine, that will make contact with the paper and smear the image.
3. Lastly, your fuser roller may be bad causing the reprint.
How to determine where the issue is, shut the machine off while it is printing and jam the paper in the image area. See if the defect is on the paper before the fuser. Eliminates the fuser ....

SOURCE: The Lexmark c530dn prints fine. Smudging down both sides.

Hello,

Your problem is caused by 2 worn photoconductor units. If you open the front door like you are changing toner, the photoconductor units will be mounted to the door that swings down. You will see should see four units one for each color, red, blue, yellow and black. If you look at the red and black units the ends will look different than the blue and yellow. The photo units have teflon coating that wears off and causes your proble. The replacement part number is C53030x and you will need 2 of them. Just replace the red and black ones and your printer will be back to normal. If you can't locate them locally, let me know and we can ship them to you.

Smudge line on side of page


Smudges are most likely from the toner cartridge. If you can take your finger and run over the print and it smudges, then it is the fuser.

4 - black ink smudges (1/32" wide x 1/16" high) in right margin


Very nice trouble shooting. The image defect you describe point to the OPC or drum unit this is essentially the toner cart. In your case black. Measureing the distance between repetitive defects is a sure way of diagnosing problems such as yours. Again nice work.

Google repetitive defect ruler for your model to help in the future.

Hope this helps

Samsung scx5315f printing black smudge along edge of page


The fact that it's printing anything suggests that it is not a Toner problem. Remove the toner, and have a look at the run inside the printer, checking for any excess toner which is in there. Also, check the Drum and Imaging Unit for damage, wear and tear etc. There will also be a static strip near the imager, with a little tab which you can sweep across the unit to clean it.

MY brother HL-5140 quits printing,and also has a black vertical line down the page before it quits. After a while, say 30 to 45 minutes, it will start printing again. But there are black smudges on the...


Sounds like a fusing error ... If your able to wipe the toner off the page its a fuser unit problem (replace fuser unit) If toner is sticking to paper but the print quality is poor , replace the drum unit  (PCU)  good luck

BLACK SMUDGING


Hmm... This sounds like it is a toner problem. If your roller is getting too much toner then it just globs it onto the paper even though the drum is not asking for it. Are you using a new toner cartridge or a re-filled one? Is it from Brother or a 3rd party? I suggest you remove the toner cartridge and check inside the printer. Clean any spilled toner. Check the toner cartridge for leaks .. give it a good shake and see if it is leaking. If you have another toner cartridge, you can replace it to test. You may need to pint a few pages to see a change. Another test could be to print a few (2-5) "BLANK" pages. The printer should not be depositing any toner. If no smudge or the smudge stays the same, then the toner cartridge is the likely problem. If the smudge is there, but gets smaller, then clean your printer.

Good luck!

Black smudge streaks on rightside of printed/copied material


Can only be two things the drum or the fuser. More than likely drum they last about 4 toners i think.

Learn the art of getting a page to stop halfway threw printing, you want to stop the page after the drum has put a image on the paper but before paper has gone threw the fuser (hotbit).

Once you have mastered the position correctly by stopping the printing by opening the door and removing drum/toner cartridge, to reveal the paper that is printed but can be rubbed off, we will know if marks are coming from the drum (you will see them) or from the fuser, if print is fine.
