ABSTRACT:
An oil distribution system for a heat and pressure fuser includes a metering assembly which gravity feeds oil along an inclined channel to a plurality of reservoirs. The metering assembly has a length which approximates the length of the fuser roll surface to be oiled. Oil is introduced into the inclined channel and fills each of the reservoirs. The reservoirs are fully enclosed save for an oil dispensing orifice located at the bottom of the reservoir. This orifice is small enough to control the rate of oil dispersed onto a primary wick located beneath the reservoir. The reservoirs are spaced in such a way that uniform dispensation of oil is provided. The primary wick receives the oil and feeds it to a fuser roll. A secondary wick helps to control the uniformity of the oil on the fuser roll.
