Photoreceptor belt seam detection and process control.

摘要

An apparatus and method for detecting the seam (98) in a photoreceptor belt (17) is provided. A sensor is positioned on one side of the belt in opposed relationship to a light source (12A) which can be a lamp dedicated solely to that purpose or light from an imager such as an LED array or a Raster Output Scanner. Illumination from the light source (12A) or the end of the array is detected by a sensor (40) when the seam (98) passes therebetween creating a characteristic output signal which is recognized by system software and used to control imager operation to ensure that latent images are not formed across the seam (98).
