Lasertulostuksen

Lasertulostus, also known as laser printing, is a digital printing process that uses a laser to produce high-quality text and images. The process involves several key steps: image formation, laser exposure, toner application, and paper transfer. In the image formation step, the printer's controller generates an image of the page to be printed. This image is then sent to the laser, which exposes the image onto a photosensitive drum. The drum is coated with a photoconductive material that becomes conductive when exposed to the laser light. In the toner application step, a toner (a fine powder made of plastic and pigment) is applied to the drum. The toner adheres to the areas of the drum that were exposed to the laser light. Finally, in the paper transfer step, the paper is rolled over the drum, picking up the toner and transferring it to the paper. The paper is then heated to fuse the toner to the paper, creating a permanent image. Laser printing is known for its high print quality, fast printing speeds, and low running costs, making it a popular choice for both home and office use.
