How the cash register reads the information of the commodity depends on the barcode scanner equipped with it. The barcode scanner uses the photoelectric component to convert the detected optical signal into an electrical signal, and then converts the electrical signal into a digital signal through an analog to digital converter and transmits it to the computer. Processing. So how do you properly install and use a barcode scanner?
First, determine the installation distance of the scanner. The reading distance of each type of bar code scanner is different, so the reading distance in the installation process needs to check the technical parameters of the relevant model. In order to avoid the direct reflection of the laser on the surface of the barcode, the barcode scanner generally does not adopt a mounting method perpendicular to the surface of the barcode, and the installation angle of the scanner has the following requirements.
Single-wire and multi-line readers are installed with an angle of 105 degrees from the exiting light and bar code surface. For the swing mirror type reader, the bisector of the side and the swing angle of the scanner is taken at an angle of 105 degrees.
Second, it is about the use of scanners. When using the scanner, align the light source port of the scanner with the bar code of the product. If the information of the product cannot be quickly and accurately scanned, the product or the scanner can be shaken properly to ensure the correct reading of the product information. At the same time, the product information has been scanned into the computer, and we can proceed to the next step, which also marks the correct installation and proper use of the scanner.
