Black dots on print outs
SOURCE: Printing with 6 black dots on right side
If the spacing between dots are the same, then you have a dirty or bad roller. If you never had this problem prior to installing the new toner cartridge, then I would suspect you have a bad one. Try a different toner.
SOURCE: printer leaves black spots on paper
The black spots mean you either need a new imaging
drum, transfer kit or fuser. You'll have to print some stuff and try to
catch where the black marks are appearing. Try this method (it's called
a Half-self test)
Load 2 -3 sheets of letter paper in tray one (manual feed) and remove paper from the rest of the trays.
From the information menu, request a demo page
The
MOMENT the tail end of the paper disappears into the printer, open the
right door. Open the front doors and release the levers for the imaging
drum and the transfer drum. Carefully remove both pieces and examine
your paper.
You should find the paper partway on the
transfer belt but not in the fuser. If you see black marks here, start
with the imaging drum. Open the shutter that covers the sea green shiny
roller and look for marks on the drum (you'll see build up on the
edges, that's normal, you should not see any scratches, pockmarks or
toner on the center of the drum). If it looks clear, take a look at the
transfer drum for marks or cuts on it's surface. (note: the transfer
drum can be cleaned off with a dry lint free cloth, do not touch the
shiny sea green roller of the image drum)
If everything looks
good there, then likely the black marks are coming from the fuser. Let
the printer sit, turned off for about half an hour to allow the fuser
to cool. You can then remove the fuser and look at the rollers to see
if there is any build up or damage there.
If you are not
seeing any obvious issues with any of these parts, then start with the
imaging drum. If you know that any of these parts have never been
changed, then change them as they do have a limit to how many pages and
how much time they can be used for.

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.

Are you using a factory new ink cartridge?
Please consider the following:
If you are using a refilled or third party cartridge that may well be your problem. Most manufacturers build logic into their products to prevent the use of “Other Equipment Manufactured” cartridges as well as re-filled cartridges.
They do this to prevent problems from contaminated inks causing problems with print quality or damaging the physical printhead.
If you are using factory new cartridges, then please call the manufacturers Technical Support for assistance with the warranty on the cartridges

Are the spots the same on every page?
Start a print from tray 1/manual feed and just as the trailing edge of paper is entering the machine; quickly open it to stop print and take out the cartridge and look at the drum and the paper underneath. If the issue is there at that point then it would point to the cartridge. If not then it is in the fuser area.
If it is the drum area:
Clean the loose toner up with a dry lint free cloth.
If it is the fuser, it may have a bad spot and would need to be replaced.
