Summary

Description
English: Applicable topics: electrophotographic printing, w:xerography, w:laser printer, w:photocopier This is an example of how an image is "written" onto the photoreceptive drum in a laser printer. In real life, the electrons are far smaller than the beam and lose their charge in clusters, but have been enlarged here to one electron per pixel for clarity of operation.

Created by Dale Mahalko, using Microsoft Word -- mostly to demonstrate what can be done, since Word was never intended for this purpose, and because I don't have a formal drawing program available. Page zoom set to 150% in Word, then screenshotted and saved as a PNG using Windows XP Paint.

(JPG re-uploaded as a PNG to make wikipedians happy.)
