Electrophotographic laser copier printer scanner
Abstract
Electrophotographic technology allows for the simple incorporation of document scanning. This function is accomplished by monitoring the specular reflection of the toned image on the copier’s photoconductor drum. Documents can be scanned at a rate and resolution comparable to normal electrophotographic printers. Scanning in this way takes advantage of the panchromatic response of the photoconductor, avoids the color-blindness issue of lasers, and prevents exposure of the user to laser radiation. Our experiments show that the principle source of noise in the scanned signal is due to an interference effect in the photoconductor and a detailed description of this effect will be presented. © 1983 SPIE.
