Explain how a laser printer works. Terms to use in your explanation include drum, toner powder, and toner cartridge.
What will be an ideal response?
To print a document, the laser printer first uses a laser beam to charge the appropriate locations on a drum to form the page’s image, and then toner powder (powdered ink) is released from a toner cartridge and sticks to the drum. The toner is then transferred to a piece of paper when the paper is rolled over the drum, and a heating unit fuses the toner powder to the paper to permanently form the image.
