ABSTRACT:
The temperature of a hot roll xerographic fuser is controlled by a control system which compares a command set point temperature to the fuser's actual temperature and energizes a fuser heater accordingly. A cold start of the fuser is distinguished from a warm start, and the command set point temperature is magnitude-programmed accordingly.
