Best to take a photo of image quality problems and post them for more accurate suggestions. Black marks can be caused by many things.

One helpful way to figuring out what is causing image quality problems is to make 1 copy at a time. Stop the copy job (open the door in mid copy to jam the machine) in a couple of locations in the copy process. By doing this you can tell at what point the marks appear on the page.

You may have a problem with a drum, developer unit, transfer belt asb, transfer cleaning unit, 2nd BTR, fusing unit.

Also, the more info you can supply the better such as: This problem is on every sheet, This problem comes and goes, This problem started after..., Only shows up when I use..., I did so and so and now I have this problem...

You need to do paper registration setup series on each tray.

clean CIS senzor and do setup. than change 746-939 and 746-940 to 50 this move the marks to the edge of the paper.
