(57) ABSTRACT

A maintenance system and method for maintaining an imaging member of an imaging device includes a pre-cleaning device to clean the imaging member; an applicator to apply release agent to the imaging member; a metering device to meter release agent on the imaging member; a reservoir to remotely store release agent; and a pump to supply the applicator with release agent from the reservoir. The saturation level of the applicator is monitored and maintained within a predetermined range. The applicator, pre-cleaning device and metering device may be independently actuated to engage the imaging member. Release agent collected by the pre-cleaning device and/or metering device may be recycled. Debris collected by the pre-cleaning device and/or metering device may be stored and/or removed.
