Barcode scanners are now one of the must-have devices for many businesses. Once you can't read barcodes properly, it will affect normal work. So what is the reason for this situation? Let's take a closer look at some of the common reasons.
The primary reason for the bar code scanner not being able to properly read the bar code may be because the scan bar code is not turned on. For the bar code of some special scanning nets, it is in the state of being closed in the factory setting, and it is necessary to open the corresponding bar code type according to the instruction manual to read the bar code information normally.
Secondly, if the angle of sunlight causes the reflected light to appear, it is also difficult to read the bar code information. For the scanner, once the photoreceptor reaches the set saturation area, the bar code information cannot be read normally. Or because the scanning distance is too close, it is impossible to scan. After all, the scanning range has certain requirements.
In addition, if the barcode itself does not meet the relevant standards, such as the problem that the contrast of the strip is not high or the ratio of the width is narrow, it will affect the scanning of the barcode. And if there is a situation where the printing is unclear or is incomplete, it will also affect its normal scanning work.
These are the common factors that barcode scanners cannot scan properly. Under the influence of these factors, the results of the scan will be affected. It is necessary to avoid the existence of these factors as much as possible to improve scanning efficiency. In addition to this, I would like to remind everyone that the scanning angle must be well grasped, vertical scanning can not guarantee the scanning results.
