Either something is lodge in between your printer's roller(which would require service tech to repair)or most likely the drum on your printer is damaged. Just replace the toner cartridge and that should fix it.

Run a 1/2 test. Put paper in the manual feed tray(tray 1). print something. And watch the paper. As the paper gets about 1/2 way into the printer, open the top cover, remove the toner. Look down at the paper. If you don't see smudged text, the fuser is probably bad. If you see the smudging, replace the toner.
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.
Try performing a test by printing a test page from Tray 1 and open the top cover as soon as the paper is 60% inside. The paper would jam below the toner cartridge before it reaches the fuser. Remove the toner cartridge carefully and verify if the smudges occur. This would eliminate the fuser. If the print quality is fine, then you need to swap the fuser.
- Try to reallign the cartridge, run a print test, after that if the issue still persist - uninstall and reinstall software - run test and re-allign again the cardtridge using software. run print test again.
