An external heater for a fuser assembly for a reproduction apparatus. The fuser assembly includes a fuser member for fusing a marking particle image to a receiver member. The external heater has a heat transfer surface adapted to be selectively engaged with the fuser member, and a device for heating said heat transfer surface. A mechanism is provided for engaging a variable portion of the heat transfer surface with the fuser member to selectively change the amount of heat transferred from the heating device to the fuser member through the heat transfer surface. |
