Abstract
A RAM system including a metering roll and a pair of metering blades, is positioned in contact with a metering roll at a location intermediate, a nip formed through pressure contact of the metering roll with a donor roll, and a supply of release agent material such that as the metering roll is rotated in the imaging process direction release agent material is metered onto the metering roll and contaminants are prevented from getting deposited on the fuser roll. A second metering blade contacts the metering roll at a location that is intermediate the aforementioned nip and the supply of release agent such that when the metering roll is rotated in the direction opposite to the process direction excess release agent material and/or contaminants are prevented from being deposited on the fuser roll.
