The Difference between a Scanner and a Copier

15.03.2021 0 iCODIS Official

The scanner is a device that uses photoelectric technology and digital processing technology to convert graphics or image information into digital signals in a scanning manner.

Scanners are usually used as external computer equipment, by capturing images and converting them into digital input devices that the computer can display, edit, store, and output. Photos, text pages, drawings, art drawings, photographic negatives, films, and even textiles, sign panels, printed board samples, and other three-dimensional objects can be used as scanning objects. The scanner extracts and combines the original lines, graphics, text, photos. The plane object is converted into a device that can be edited and added to the file. The input system belonging to the computer-aided design (CAD) in the scanner forms the pre-screen computer processing system through the interface of computer software and computer, output equipment (laser printer, laser plotter). It is suitable for office automation (OA) and is widely used in sign panels, printed boards, and printing industries.

The copier refers to an electrostatic copier, which is a device that uses electrostatic technology to copy documents. The copier is an analog mode and can only copy documents truthfully.

Digital copiers will make it possible to store, transmit, and edit and typesetting images (image synthesis, information addition or deletion, partial enlargement or reduction, and error correction). It can be connected to computers, word processors, and other microprocessors through interfaces, and becomes an important part of the regional network. Multi-functionalization, colorization, low cost and miniaturization, and high speed are still important development directions.

Obviously, the scanner is to digitally convert paper materials, etc., while the copier only copies the text. So the functions implemented by the two are completely different.
