ABSTRACT:
Apparatus for applying release oil to a fuser roller pair (10a, 10b) ina xerographic copier comprises an elongate trough (41) containing a supply of oil (42) in the base (44) thereof, and a wick (45) for drawing up the oil from the trough and applying it to a metering roller (47). The metering roller applies the oil to a doner roller (48) which in turn transfers the oil to the heated roller (10a) of the fuser roller pair. The amount of oil on the metering roller (47) is checked by a blade (49) and surplus oil removed by the blade is allowed to fall back towards the trough. In order to promote enhanced distribution of oil along the length of the trough a series of ramps (51a, 51b, 51c) is sawtooth configuration is provided in or adjacent a side wall of the trough beneath the blade (49) to receive the oil removed from the metering roller before it is returned to the base (44) of the trough. The base of the trough may slope in the opposite direction to the ramps to establish continuous circulation for the oil.
