Analysis of the Working Principle and Typical Fault of Laser Printers
A laser printer is composed of laser scanning,information processing,the electronic drive system and the print control system,its core component is a laser beam,and its working principle is to produce reflected light through irradiating the laser beam on printing paper,then transmit the reflected light and the image information on the photosensitive drum to the electronic computer together,and finally analyze the printed document through the electronic computer to make a judgment and output a document.With the rapid development of science and tech-nology in China,more and more advanced equipment has entered people's daily life.In the process of using laser printers,it will inevitably encounter a variety of problems,and this paper analyzes the working principle,common faults and treatment methods of the laser printer,in order to provide reference for the majority of users.
