Abstract
ELECTROSTATIC OFFICE COPIERS MAY BE CONVERTED TO DIGITAL DATA PRINTERS BY ADDING A MODULATED HENE LASER AND RASTER SCANNING WHILE RETAINING THE CHARGING STATION, TONING STATION AND PHTOCEPTOR DRUM.THE MAJORITY OF PRESENT OFFICE ARE SE-BASED PHOTOCEPTORS, BUT THE SPEED IS LIMITED DUE TO THE NARROW-BAND RESPONSE AND SOFT SURFACE. FURTHERMORE, SE ALLOYS WHICH EXTEND ITS SPECTURAL RANGE ARE TOXIC. PLASMA-DEPOSITED AMPHOROUS-SILICON (A-SI), ON THE OTHER HAND, APPEARS TO BE AN IDEAL PHOTOCONDUCTOR FOR THE PHOTORECEPTOR DRUM SINCE ITS SPECTRAL BAND IS WIDER, ITS SENSITIVITY IS HIGHER AT THE 633NM LASER LINE, ITS SURFACE IS HARDER, AND IT IS BIOLOGICALLY BENIGN. DIGITAL DATA PRINTERS OR INTELLIGENT-COPIER-PRINTERS MUST OPERATE SAFELY AT HIGH SPEEDS IN ORDER TO INTERFACE THE DATA STREAM OUTPUT FOR COMPUTER AND ELECTRONIC OFFICE. THUS THE DEVELOPMENT OF A LONG-LIFE, SENSITIVE AND SAFE PHOTORECEPTORWOULD BE OF NATIONAL TECHNOLOGICAL AND ECONOMIC SIGNIFICANCE.
