Abstract
This invention provides an image-forming machine with a user detection system. The image-forming machine has image-forming equipment and at least one sensor. The image-forming equipment may include a photoconductor, one or more chargers, an exposure machine, a toning station, a fusing station, related equipment, and accessories. The image-forming machine may also include a sensor interface and a communication link. The sensor is monitored to detect when a user is near the image-forming machine. An output signal from the sensor indicates a user presence near the image-forming machine. A warm-up procedure is started in response to the output signal of the sensor.
