Image scanner

It is a device that reads an item (image, text) and creates a digital copy of it.

Operating principle

Scanning with an analog-to-digital converter creates a digital description of the image. The final result of the scanner is a file that can be opened on a computer, phone, or tablet).

Stages of scanner operation

• Place a sheet of paper on the side you want to scan on the scanner's work surface
• Select the settings (resolution, color, file format, etc.)
• Scanning is initiated by a button on the scanner or by a command from a device connected to the scanner
• When the scanning signal is received, the mechanisms that move the lamp across the entire area are activated
• The lamp shines on the data carrier, reflecting the information on the mirror system. This system allows the data to enter the analog-to-digital converter
• The received information is sent to a computer
