The Toners are all Original and it happens when you are printting on color & black & white. Even when you printting the cleaning page it appears.

Sounds like the high voltage is not working nicely.Clean the contact points on the toners and the once in machine.Hope this will solve your problem.

Lets not leave this to chance. You have a very fine diagnostics built into the printer. Attached are instructions for disabling cartridge check. Use this procedure to disable and then swap the cyan and black toners and to some print quality tests. If the background turns to blue then you may be having high voltage issues. If it is still grey or goes away with the swap, then odds are the black toner cartridge has an issue. My money is on the black toner.
