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.

How do I fix my Samsung Multi-function laser printer which has started to print smudged pages.

try to stop the sheet just before it enters the fuser and see if the marks are on the paper already. if not then it has to be the fuser if they are them you have another issue.

The dark rectangle appears because you have the closed captions on and set to TEXT. Closed captions set to CC1 puts the words on the screen and TEXT puts a black box on the screen. Go into the menu, navigate to the page with closed captions and set your captions to OFF.

HP4-smudged copies of printed text are appearing lower on the page...Any ideas on the fix

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.

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

Poor quality smudge and ink blotting marks in the centre of any printed document

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.

Black ink smudges for color print mode only, not for grayscale

- 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.
