Abstract
A fuser has a protuberance extruding lengthwise from the surface of a heater opposite the interior surface of an endless belt and is positioned in transverse relationship to the interior surface of the endless belt. A pressure roller defines a nip with the endless belt wherein the nip has an entrance side and an exit side and wherein the position of the protuberance adjacent to the nip creates pressure upon the endless belt. The print media sheet is driven through the nip in reaction to the pressure applied by the pressure roller to the belt. The position of the protuberance and the pressure created upon the endless belt directs the lubricant from the endless belt surface to the nip.
