Claim:
A drum maintenance system for use in an imaging device, the system comprising: a reservoir including a supply of release agent; an applicator configured to receive release agent from the reservoir and to apply the release agent to an intermediate imaging surface of an imaging device moving in a process direction; a first metering blade positioned in wiper mode at a first position adjacent the intermediate imaging surface and configured to meter the release agent on the intermediate imaging surface applied by the applicator; a second metering blade positioned in wiper mode at a second position adjacent the intermediate imaging surface; and a second metering blade positioning system operably coupled to the second metering blade and configured to move the second metering blade into engagement with the intermediate imaging surface to further meter release agent applied to the intermediate imaging surface by the applicator in response to printing a first side of a duplex print job and out of engagement with the intermediate imaging surface when printing simplex print jobs and when printing a second side of a duplex print job.
