ABSTRACT:
A method and apparatus for sensing multiple process parameters with a single sensor in a printing machine. The sensor senses the photoreceptor belt seam to insure that the latent image is not formed on the belt seam; the toner density is used to control the toner dispenser, photoreceptor charging, developer bias, image exposure and image processing systems; registration marks which are used to control registration of multiple images; presence of copysheets in a paper transport which is used to indicate timing and paper jams or faults; and copysheet type which is used to control the fusing process time. In order to measure all of these parameters, the sensor is uniquely located in printing parameter sensing relationship to the photoreceptor and along the paper path of the printing machine.
