Detailed explanation-1: -Laser printers have replaced such printers in most commercial settings. Laser printers employ a focused beam of light to etch patterns of positively charged particles on the surface of a cylindrical drum made of negatively charged organic, photosensitive material. As the drum rotates, negatively charged…

Detailed explanation-2: -Is a laser printer an output device? Yes, a laser printer is an output device. A laser printer is a peripheral that connects to a computer and can print out a document or picture that is known as a hard copy.

Detailed explanation-3: -The revolving drum gets a positive charge. The system’s electronics convert the image into a laser beam. The laser beam bounces off a mirror onto the drum, drawing the image on the drum by burning a negative charge in the shape of the image. Then the drum picks up the positively charged toner from the toner cartridge.

Detailed explanation-4: -A laser printer consists of these major components: drum cartridge, rotating mirror, toner cartridge and roller. The drum cartridge rotates as the paper is fed through.

Detailed explanation-5: -In order to achieve this, laser printers usually use a corona wire which carries a high voltage. Once the drum is adequately charged, the laser beam is guided onto the surface of the drum via mirrors which precisely scans the images onto the surface of the drum.
