Scanner, is the use of photoelectric technology and digital processing technology to scan the pattern or image information into a digital signal device.
Scanners are commonly used outside computer instrumentation by capturing images and converting them into digital input devices that the computer can display, edit, store, and output. Scanner photographs, text pages, drawings, art pictures, photographic negatives, film films, and even textiles, sign panels, printed board samples and other three-dimensional objects can be used as a scanning object, extract and convert the original lines, graphics, text, photos, plane objects into a device that can be edited and added to the file. Scanner belongs to the computer aided design (CAD) in the input system, through the computer software and computer, output equipment (laser printer, laser plotter) interface, the composition of screen pre-press computer processing system, and is suitable for office automation (OA), widely used in the sign panel, printed board, printing industry, etc.

Testing standard

The scanner CE certification test standard:

Scanners exported to the EU, or sold in the EU market, must do the EU mandatory CE certification. Scanner CE certification standard: EN60950.
En60950-1: Information technology product security: General requirements

EN60950-21: Information technology equipment. Security. Part 21: Remote power supply

EN60950-22: Information technology equipment - safety - Part 22: Equipment installed outdoors

EN60950-23: information technology equipment - safety - Part 23: large data storage equipment

Scanner CE test certification EN60950 test items:
