ABSTRACT:
A release agent management (RAM) system including a metering roll supported for contact with release agent material contained in a sump. A donor roll is provided for applying oil deposited thereon by the metering roll.
A metering blade structure for metering silicone oil onto the metering roll has two modes of operation. In one mode, a wiping action of a metering blade meters a relatively large quantity of silicone oil to the roll surface for accommodating the fusing of color toner images. In another mode of operation, a doctoring action is effected for metering a relatively small amount of silicone oil to the roll surface for accommodating the fusing of black toner images.
