Abstract
A waiting time display system specifically for use in a copying machine includes a temperature sensor for monitoring the specific temperature of heat fixing rollers. Electronic processing is responsive to the varying signal outputs of the sensor and correspond to the rise of the temperature detected. A display panel is driven so that a plurality of lights are sequentially activated and deactivated to indicate time and temperature. An audio signal can also be provided to indicate the machine can be activated for copying. An operator can now gauge the amount of time until the copy machine is capable of being operative.
