Abstract
A method and apparatus for fusing toner to a laser printed page. The apparatus includes a photosensitive drum, a laser optic system for tracing an image on the photosensitive drum, a toner supply electrically charged opposite the image traced on the photosensitive drum, and an ultraviolet light source for imparting energy to the toner to fuse the toner to the page. The apparatus facilitates faster print speeds and lower energy consumption than conventional laser printers that require heating elements to fuse the toner to the page.
