Abstract
Wear of the belt (1) of a belt fuser is minimized by use of a high viscosity lubricant of perfluoropolytrimethylene oxide grease between the inside of the belt and the heater element 6. To avoid damage of the belt at turn on, the belt is heated to a predetermined temperature before force is applied to move the belt.
