Abstract
A drum maintenance system for use in an imaging device includes an applicator configured to apply a release agent to a surface of an intermediate transfer drum of an imaging device at a first flow rate, and a reservoir spaced from the applicator including a supply of the release agent for the applicator. A first fluid path fluidly couples the reservoir to the applicator for delivering release agent to the applicator; and a second fluid path fluidly couples the applicator to the reservoir for recirculating release agent back to the reservoir. A delivery pump is configured to pump release agent from the reservoir to the applicator via the first fluid path at a second flow rate; and a recirculation pump is configured to pump release agent from the applicator to the reservoir at a third flow rate. The second flow rate is greater than the first flow rate, and the third flow rate is greater than the second flow rate.
