A multi-function reproduction apparatus selectively operable to either copy, write, or read. For reading, the image to be read is processed xerographically to provide a developed image on the apparatus photoconductive member which is raster scanned with a high intensity beam. Light reflected from the photoconductive member is captured in an elongated rod-like collector disposed proximate the photoconductive member and transmitted axially along the collector rod to a light detector at one end where the light is converted to an electrical image signal or pixel by the detector. The intensity of the beam is regulated to assure a uniform light intensity at the detector irrespective of the distance through which the light travels within the collector rod.
