Barcode scanner can not sweep out the barcode root cause and the solution


Barcode Scanner can not sweep out the barcode, in this case to understand clearly, whether can scan the barcode but can not upload, or the scanner have light out, but do not have data output.

If it is that the scanner can scan the barcode but cannot upload it to the computer. That is, the computer is not connected to the scanner. If the wired scanner needs to check the port and line.If it is a wireless scanner, reset the matching receiver. If not, return to the factory and check to see if it is a receiver problem.

If you do not scan the barcode, you need to check whether you have dropped the scanning gun, the Angle of the lens is wrong.Whether the dust on the dustproof lens of the scanning gun is too much, wipe it to see whether it is ok, if not, can only return to the factory for maintenance.

There are several possible reasons:

1. There is no function to open the bar code reading.

2. The bar code does not conform to the specification, such as the lack of necessary blank area, the comparison between bar and blank is too low, and the width and width ratio of bar and blank is not suitable.

3, direct sunlight, photosensitive devices into the saturation zone.

4. The barcode surface is covered with transparent material, with too high anti-luminosity. Although the eye can see the barcode, the collector cannot read it.

5, hardware failure, and scan gun manufacturers contact for maintenance.

In the process of use may also encounter such a situation, after reading a bar code, the scanning gun crashed, because of the protection of the scanning gun, if the barcode data transmission error, will automatically enter the protection state, so as to prevent data loss.If the untransmitted data is read, the scanning gun can be reused.If this happens, check the wires and protocols carefully.After confirmation, turn off the scanning gun and open it again for normal use.
