If its spots this could have been from the cartridge or the fusser unit...
Do a half print test...send a print page to your printer listen to the printer print as soon as you think the printer has printed some little bit switch off the printer...take the cartridge and view the printed portion can you see the spots..if not.....than its your fusser unit thats marking the paper....remove the half printed paper slowly.....not to tear it......remover the fusser unit(hot unit)........at the back of the printer....towards the top....on the unit it self you will see a Teflon paper ....move the gear on the far end of the fusser unit itself and view if there is any spots....try cleaning this spots slowly as not to damage the Teflon or mark the Teflon.....

I have a Lexmark C522 Color Laser printer, all cartridges are showing as ok, no error messages but printed pages have specks of magenta toner on them


It sounds as though you have a leaking toner cartridge. If you aren't using Lexmark brand toner, that is VERY likely.. nobody seems to be able to make a good compatible cartridge. Test by replacing it.

Consistent dots down print


Try to print clean page ,
Print a cleaning page During the printing process, paper, toner, and dust particles can accumulate inside the printer and can cause print quality issues such as toner specks or spatter, smears, streaks, lines or repeating marks. Follow these steps to clean the printer's paper path.
  1. Load copier-grade paper (not bond, heavy, or rough paper).
  2. On the printer's control panel, touch the Menu button.
  3. Touch Configure Device .
  4. Touch Print Quality .
  5. Touch Process Cleaning Page .
A Cleaning message appears on the printer control panel display while the cleaning is taking place. The cleaning process takes a few minutes to complete. Do not turn the printer off until the cleaning process has finished. A page will be printed when the task is complete. Discard the page. You might need to repeat the cleaning process to thoroughly clean the printer. Print a few more pages to see if the problem is resolved.

Brother HL 5140 has black specks on the page


There's probably something wrong with the drum unit. I would check the manual on how to change the drum unit. Good luck!

I am getting white specks on all four colors on my phaser 8500 and some black smudges. I just did a smudge clean and it helped, but it didn't clear it.


Hello.

Try a laser printer roller cleaner (paper sheets), like PathKleen or Perfect Data. You may need to run sheets through several times before the cleaning is complete. Do not use a sheet more than once.

Hope this helps.

Specks of blue on my printing.


Replace the cyan drum unit. If the specks are always in the same line there is small ding in the drum. If the specks are random then the cleaning blade inside the drum unit is bad. When ever the defect is just one color it usually is that color drum unit.

Small lines or specks on the right side of every page


Did you try cleaning the lense? You'll have to pull all the toners and open the little door below and wipe with a clean lint free cloth in ONE direction.

A faded line prints across the page


The imaging bar has speck of dust on it.
Turn printer OFF.
Open the printer. Pull out the transfer roller. Should have a big green handle. Do not touch the roller.
Look inside for a shiny rectangular block about 5inches x 0.5 inch.
This is the imaging bar. Using a lint free cloth with no chemical and no water, gently wipe this bar to remove any specks of dust/paper specks.
Put roller back.
Close the printer.
Turn printer ON.
Problem fixed.
