ABSTRACT:
Fuser apparatus for fixing toner images to copy substrates by passing the substrates between two pressure engaged fuser members one of which is heated. A control for effecting movement of the members at two different speeds is provided such that the members are moved at the higher speed when a small number of copies are made and at the higher speed and then at the lower speed when a large number of copies are being made. The control includes a temperature sensor for sensing the temperature of the heated member which is used to generate a signal when the temperature of the member falls to a predetermined value, the signal being employed for changing the speed of the members from the higher speed to the lower speed.
