A scanner is a device that uses optoelectronic technology and digital processing technology to convert graphic or image information into digital signals through scanning. Scanners are typically used for external instrument devices on computers, capturing images and converting them into digital input devices that the computer can display, edit, store, and output. Scanners can be used as scanning objects for photos, text pages, drawings, art drawings, photographic negatives, film films, and even 3D objects such as textiles, signage panels, printed circuit board samples. They can extract and convert original lines, graphics, text, photos, and flat objects into devices that can be edited and added to files. The scanner belongs to the input system of computer-aided design (CAD), which forms a pre printing computer processing system through computer software and computer output equipment (laser printers, laser plotters) interfaces. It is suitable for office automation (OA) and is widely used in signage panels, printed boards, printing industries, and so on
