Abstract

In an electrophotographic printing machine, a roll fuser fre-quently employs release material. The release material is applied to the heated fuser roller, As shown in the figure, fuser roll 44 is in operative communication with dispenser 48. Dispenser 48 includes a housing 66 defining a chamber 68 for storing the release material therein. Fuser roll 44 has a portion thereof rotating in chamber 68 of housing 66. End seals 72 prevent fluid side leakage. A layer of release material is coated on roll 44 as a portion thereof passes through chamber 68. Baffle plates 70 are provided to control solidification of the release material. Plates 70 extended in chamber 68 of housing 66 in a direction substantially normal to the longitudinal axis of roll 44. Plates 70 compartment-alize chamber 68 to prevent splashing and sloshing of the release material when it is in the liquid state. In particu-lar, plates 70 control splashing and sloshing of the release material during the withdrawal and insertion of the fusing apparatus into the printing machine. Baffle plates 70 are made from a metallic material so that the surface thereof is
