Re: spots on paper
Look on the image drum (bottom of toner cartridge) are there spots on that?? if so clean carefully so as not to damage it or replace the cartridge. If this is not the case open the cartridge door during a print, but before the paper fully enters the fuser and check if the spots are already there, if not the fuser is causing the problems.

You didn't say that you swapped out the toner. Let's come back to that point later.
Put paper in the manual feed tray. Print something. As soon as the paper feeds halfway into the printer, open the top cover. Pull out the toner, look down at the paper. Is it mostly black? If the answer is yes....replace the toner. Vacuum out the inside of the printer and print again. I think you have a bad toner cartridge
I think you should contact the manufacturer or vendor who sold you the cartridge. The standard warranty is 90 days. I believe that it will prove to be a bad toner/ drum (which are the same thing for this printer.)
Besides that you can do a "half-test". Stop the print job half way by opening a cover during the print process, before it is transfer to the paper and fused. Look at the drum or transfer belt and see whether the defect exists early in the print process.
There may also be a contact problem with the black toner. Check for bent metal on the toner, or chassis that should mate and conduct charge to the toner.

How do I clean white or black spots on printed documents?
Description:First make 10 to 15 copies of a blank, white sheet of paper.
If you still see the spots on printed documents after making multiple copies, clean the drum unit as follows:
Remove the drum unit and toner cartridge assembly, and then remove the toner cartridge from the drum unit.
the print sample in front of the drum unit so you will know the exact
position on the drum that is causing the poor print.
Turn the black gear on the drum as you check the surface of the OPC drum.
The OPC drum is photosensitive so do not touch it with your fingers.
you find the substance on the drum surface that matches the print
sample, gently dab the surface of the OPC drum with a cotton swab that
is lightly dampened with isopropyl alcohol.
Do not use a scrubbing or wiping motion because this might damage the drum.
Do not try to clean the surface of the OPC drum with a sharp
object, such as a ball-point pen, because this might cause permanent
damage to the drum unit.
If the print quality still has not improved you need to install a new drum.
hello, you might want to do a half test, i will explain, when the printer starts printing, open the front cover after paper has started to pick up and has gone halfway into machine, pull toner cartridge out, and check print, if the black spots are there, then the problem is toner, if not then it would be fuser.
A. The drum is not
charger corona wire is probably broken or not making good electrical
charger corona wire may be part of the toner cartridge. Try
and reinstalling the toner cartridge. If that doesn’t work, try
another toner cartridge.
It sounds like the toner drum may be having some issues, it can be replaced but it is not easy / inexpensive. It may be more cost effective to replace the unit. Otherwise it will need a replacement part for sure.
You either have a bad spot on the drum or a bad spot on the fuser rollers. Replace the cartridge first. If spot continues, take cartridge out and get inside with a flashlight. You'll probably find a piece of paper stuck to a roller.
