How to Install a Barcode Scanner at the Cash Register

The information that the cash register reads the goods is the barcode scanned by the bar code scanner, and then the bar code scanner converts the detected optical signal into an electric signal using photoelectric elements, and then converts the electric signal into a digital signal through an analog-digital converter. Computer processing. Barcode scanners are commonly used in supermarkets, convenience stores, tea shops, bakeries, etc. How to properly install and use bar code scanners?

First of all, determine the installation distance of the scanner. The reading distance of each type of barcode scanner is different, so the determination of the reading distance during the installation process requires consulting the technical parameters of the relevant model. In order to avoid direct reflection of laser light by the barcode surface, barcode scanners generally do not adopt an installation method perpendicular to the surface of the barcode, and the installation angle of the scanner has the following requirements.

The single-line and multi-line readers maintain a 105-degree inclination of the outgoing light and the barcode surface when installed. For the oscillating mirror reader, the side of the scanner and the bisector of the oscillating angle are set at an angle of 105 degrees.

Then it's about using the scanner. When using the scanner, align the scanner's light source port to the barcode of the product. If the product information cannot be quickly and accurately scanned, you can shake the product or the scanner to ensure the correct reading of the product information. When it is heard, the product information has been scanned into the cash register. At this time, we can proceed to the next step. It also marks the correct installation and correct use of the scanner.
