Abstract: A system and method are provided for enclosing a plurality of cleaning unit components in a moist cleaning unit environment, the plurality of cleaning unit components cooperating to employ a cleaner roller in an image forming device to facilitate effective cleaning of a reimageable surface in an image forming device using a proposed variable data digital lithographic image forming architecture. A range of solvents may be applied to a hard smooth high surface energy surface of the cleaner roll and a cleaning unit component internally positioned within the cleaning enclosure to clean the surface of the cleaner roll. Mechanical components are properly placed prior to the cleaner roll-reimageable surface nip to ensure that residual liquid on a surface of the cleaner roll is removed.

Abstract: A system and method are provided for providing an improved inker unit surface cleaning and conditioning system, including in a single anilox chamber blade system, for improving image quality, including eliminating ghosting, in a proposed variable data digital lithographic image forming architecture. Techniques are provided to remove acquired oil from an inking member. A particularly-configured containment encloses a cleaner (disturber) roller to emulsify the acquired oil on the inking roller. The cleaner roller is preferably configured with a pliable surface including a silicon roller surface over a porous base. The silicon roller (1) absorbs dampening solution oil; and (2) agitates ink that may be still held in certain cells/cavities of the inking member or roller. In embodiments, a vacuum pressure is applied to the inside of the hollow cleaner roller to better remove the residual ink and dampening solution from the inking roller.
