Q. How does the laser printer works?
Answer:-
When a text or else image is entered into the CPU it produces a series of varying voltages. This manages a LED (light emitting diode) in the printer. This releases flashes of laser when it falls on a charged photo conducting drum. The area correspond the text or else image will either be neutralized or else oppositely charged. A toner which has the similar charge as the background is sprayed onto it. It merely sticks to the text or image and is repelled by the background. A fresh paper is at present pressed onto the toner as well as is slightly heated so that it sticks firmly on the paper.
