Sometimes, when we are using a barcode scanner, we found that it can read barcodes, what are the reasons?

1. It may be because the scanning barcode is not open. For some special barcodes of scanning network, they are turned off in the factory settings, and it is necessary to turn on the corresponding barcode type according to the instruction manual to read barcode information.

2. If the angle of sunlight cause the reflected light, it is difficult to read the barcode information. For the scanner, once the photoreceptor reaches the set saturation area, the barcode information cannot be read. Or because the scanning distance is inappropriate, it can't scan.  After all, the scanning range has certain requirements.

3. If the barcode itself does not meet the relevant standards, for example, the contrast of the bar space is not high or the ratio of width and width has problems, it will affect the scanning of the barcode. And if the printing is unclear or incomplete, it will also affect its normal scanning work.

These are the common reasons for barcode scanners not scanning properly. Under the influence of these factors will affect the scanning results. To avoid the existence of these factors as much as possible can improve the scanning efficiency. In addition, the angle of scanning must be grasped, and vertical scanning cannot guarantee the scanning results.
