A laser (typically, an aluminium gallium arsenide (AlGaAs) semiconductor laser) projects a graphic of the page to be printed onto an electrically billed, selenium-coated, rotating, cylindrical drum[10] (or, more commonly on subsequent versions, a drum named an organic photoconductor manufactured from N-vinylcarbazole, an organic and natural monomer). Photoconductivity enables the billed electrons to fall from…
