Detailed explanation-1: -An electrostatic charge is applied to the paper to attract toner particles. A. After a laser has created an image of the page, the developing roller uses a magnet and electrostatic charges to attract toner to itself and then transfers the toner to the areas on the drum that have been exposed to the laser.
Detailed explanation-2: -The fuser assembly presses and melts the toner into the paper. The transfer corona transfers the toner from the drum to the paper.
Detailed explanation-3: -The principle used in a laser printer is static electricity. Initially, the photoreceptor drum is charged positively by corona wire by applying an electrical current on it. Then the printer shines a tiny laser beam across the surface according to the data sent by the computer, one horizontal line at a time.
