    Black spots on the sheet on iR 1730 .

    Good evening to everybody !
    I'm here again with another problem !

    Black spots when copying or printing with iR 1730 !

    I changed the fixing unit, I setted a new value for the temperature (from 7 to 6), I decreased the amount of the toner, but nothing !
    The defect remains !


    Suggestions ?
