Abstract
An apparatus for applying release oil to a fuser roller pair in a xerographic copier comprises an elongated trough containing a supply of oil in the base thereof, and wick for drawing up the oil from the trough and applying it to a metering roller. The metering roller applies the oil to a donor roller which, in turn, transfers the oil to the heated roller of the fuser roller pair. An upper guide device is provided on the exit side of the fuser by ribs formed integrally on the underside of the trough. The trough and guide ribs may thus have a compact configuration that is suited to inexpensive manufacture, e.g. by molding, as a one piece item. A lower guide member is fixed to the fuser assembly. Also, stripper fingers are mounted integrally on the trough adjacent the upper guides, the fingers being provided with slots through which the ribs extends.
