LASER PRINTER (Cont…)
The Process:A computer sends printed matter to the printer as vector information.
The vector information is converted into dots.
A Laser Unit, located at the back of the printer, shoots the laser beam while printing. The laser fires when there is a dot and remains off when there is blank space.The vector information is converted into dots.
The onboard electronics control the movement the laser and the beam is passed through the lens filter to the Photoreceptor drum.
A complete positive charge is given to the drum, by the corona wire, when it starts rotating. The corona wire is a wire that carries electrical current and which runs through it. When the drum rotates, the miniscule laser beam hits across the surface in order to discharge certain places.
The laser moves in a horizontal pattern creating the dot patterns on the photoreceptor drum. Once the entire line of dots is completed the drum rotates to receive the next line.
