OIL HANDLING AROUND A METERING ROLL

摘要

Release Agent Management (RAM) system for a heat and pressure fuser. The open pool of oil associated with prior art RAM systems is replaced with an oil saturated wick the lower end of which is immersed in oil. The oil is held in a container with a sealed lid that has a slot through which the wick passes allowing the wick to transport oil from the container to a metering roll outside of the container. A depression in the container lid that cradles the wick under the metering roll allows oil to collect in the portion of the wick laying on the container lid. The shape of the depression prevents oil from flowing back into the container through the slot and from flowing to some lower part of the container lid. The wick is compressed approximately 50% between the metering roll and container lid. A removable seal is provided which is attached to the lid such that the RAM can be shipped without oil spillage.
