Bar code scanning guns when using light normally on don't go out how to return a responsibility? Common problem solving methods

With the development of mobile Internet, the application in the retail business super to bar code scanning guns, it can help the supermarket sales of goods, in and out of the effective management of efficiency. Now, many users just contact barcode scanning gun, to know it is still far from enough, a lot of people don't know how to use after bought, couldn't scan the barcode and other issues accordingly. Let's vision to introduce you to bar code scanner scans the LED light is not on common problems.

the use of bar code scanning guns
1, the scanning gun is not used when the light keep normally on don't go out.
root cause analysis: accidentally set the light is normally on state.
the solution: restore factory Settings, close the normally on it.
2, scanner scans the LED lamp is not bright, and there is no any response?
cause analysis: it could be the power of the scanning gun didn't get through, or cable interface is not tight, lead to poor contact.
solution: first check whether the power of the scanning gun connection, if have connection, you need to check whether the interface of the data line is loose, it is best to connect the data line and scanning gun in again, to ensure the normal use electricity.
3, scanner connection is complete, the LED has been flashing, and there is no voice, nor a scan?
root cause analysis: internal problems may be scanning gun, are generally IC poor contact.
solution: this happens please find dealers, manufacturers for repair.
4, scanning gun start normal, and there will be a laser, but don't read the code?
root cause analysis: the cause of this problem will have a lot of kinds, the first may be the bar code system has been closed; The second may be barcode has been damaged; A third possibility is bar code quality problems, that is to say, barcode printing is not in conformity with the standards; Fourth, dustproof lens is clean; 5 kinds of hardware may be scanning guns or motherboard failure.
solution: first of all, you can open the corresponding bar code system, and then check whether the bar code is damaged.
5, serial port scanning guns have connection is good, but reading code when no data?
cause analysis: maybe it's not set serial port mode scanning gun,
solution: reference manual, sets the scanning gun to serial interface mode.
6, scanner scans the bar code, hum normal but there is no data transfer?
root cause analysis: may be scanning gun scan setting is not correct, no data transmission caused by scanning gun, another reason could be that the transmission wire malfunctioned, that no data transmission.
solution: can restore factory Settings, refer to instruction manual reset scanning gun, ensure that the corresponding set of the data line is correct.
7, why some bar code scanning guns sweep that some barcode scanning out?
cause analysis: the first is probably the barcode code system do not conform to the requirements of the scanning gun, the second is probably didn't activate the barcode scanning gun, the third may be barcode have been broken. The fourth could be a hardware failure.
solution: restore factory Settings, refer to the instructions to activate the barcode code system, or replace the barcode.
the application of bar code scanning guns, not only need technical support users patiently to study how to realize these failures, so as to solve these faults, make bar code scanning equipment can better serve ourselves.
