Question about Brother HL 5250DN Laser Printer
The black marks are most likely from a worn image drum. I would check the image drum (the unit that the toner fits into) for wear marks. If worn i would suggest to replace it. The Brother part is DR-250 and is available at most office supply stores.

Did you change the Toner cartridge? If that did not fix it :
Then the Fuser needs replacing. If you take the Fuser out from the rear, and rotate the drum in it, you will see the marks. You can try to clean it but experience shows that you will have to replace it.
If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.

This sounds like the photoconductor units for both black and blue need to e replaced. Open the front of the printer like you are changing toner cartridges. On the front door parts that opens to you there will e four pieces, 1 for each color. Look at the one with blue on it and the one with black and look on the ends of these, they are the photoconductor units. I bet both of the colors have worn sections compared tothe magenta and yellow ones. The replacement part number is C53030X and you will need 2 of these. They have a life span just like toner and have to be replaced too.
I hope this helps,

Testimonial: "Spot on... solved the problem"
The black marks normally comes from a worn fusing unit. in most printer nowadays, you buy a maintenance kit that comprises of roller, pickup rollers, fusing unit and drum. after changing those items mentioned above, you should correct the 3 black marks on your printouts.
