Check the drum unit. Rotate the optical cylinder slowly, looking for a scratch or clot of toner on the drum. You may need to clean it with compressed air or VERY gently with alcohol and a cotton ball. If the drum cylinder is clear of defects, check the fuser at the back of the machine for the same. A drum can be cleaned or replaced, a trashed fuser is not repairable. It may also be cheaper to replace the machine than to replace the drum of course.

It sounds like your fuser sleeve of your printer need replacement, or just to be cleaned. You can use Isopropile alcohol 99% to clean it.

If that does not remove the mark on the pages, then try to replace the fuser roller.

SOURCE: I have small black dots

hi

First try printing a few pages to try and clean the drum unit. If the problem is not solved after printing a few pages, the drum unit may have glue from a label stuck on the drum surface.

SOURCE: Brother HL-2035 laser printer, black

Dots, Lines and smudges on the printouts are due to dirty/ deteriorating cartridge and cleaning the green drum of the cartridge may help temporarily. Take out the cartridge and gently clean the roller/ green drum with a dry, soft, lint-free cloth wiping off the toner dots marks/ lines.
Also, make sure that the visible inside of the printer is clean and ther is no spilled toner inside, which sometimes results in dots.
Let me know if any further clarification/ assistance is required.


GoodLuck!
Dont forget to appreciate the solution if I could have been of any help!

I have small black dots down the left hand margin of each printed page approx 10cm apart. MFC8870DW


10cm means it's caused by a large roller. The only roller large enough for that would be in the drum. Replace your drum and it should clear up, the model number of the drum is DR520.

It's probably the toner cartridge again. See if you can spot defects at the cyan drum unit that matches the marks on your printout.

Faded on left hand side


If it only happens with the black then you need to change out the black toner cartridge. The good news is isn't doesn't happen with color so it more than likely not the printer but the toner.
