  • Publication number: 20140270880
    Abstract: Methods and devices provide an electrostatically chargeable surface within a printing apparatus and cause a movable lubricant applicator to contact the electrostatically chargeable surface. The movable lubricant applicator is movable to be in contact with the electrostatically chargeable surface, or out of contact with the electrostatically chargeable surface. Such methods control the movable lubricant applicator to be in intermittent contact with the electrostatically chargeable surface during printing operations of the printing apparatus.
