how does a laser printer work
Next, a precise laser beam scans back and forth over the printerâs photoconductive drum as the printer draws in a clean sheet of paper. A special rotating mirror does the hard work of sending the beam to where it needs to be. The key is that wherever the laserâs beam hits the drum, it selectively removes the static charge on the drum on that exact spot. Some printers use light emitting diodes instead of a laser to imprint the image on the drum. To get this latent image onto the page, the drum next selectively picks up toner where the drum remains charged. This creates a reverse image of what was on the drum. This image is then transferred to the paper.
