Fault 1: The scanner can't scan the barcode Solution: In this case, you must first understand whether you can scan the barcode but not upload it, or the laser but not scan the barcode. You can scan the barcode but do not upload it to the computer, that is, the computer and the scanner are not connected well, if it is wired, you should check the port and wire, if it is wireless, you must reset the pairing receiver. It is also possible that there are several possible reasons for this:

1. There is no function to open and read this barcode;

2, the bar code does not conform to the specification, such as the lack of necessary blank area, the contrast between the bar and the empty is too low, and the width and width ratio of the bar and the empty are not suitable;

3. Direct sunlight, the photosensitive device enters the saturation zone;

4. The surface of the barcode is covered with transparent material, and the reflectivity is too high, although the eye can see the barcode, but the collector reads the conditions strictly, and can not read;

5. If the hardware fails, contact your dealer for repair.

Fault 2: LED is not lit, no buzzer, no laser Solution: It may be that the power supply of the scanner is not on, the scanner is not powered on, or the data cable interface has been loosened, and the contact is poor. Check the cable of the scanner to make sure that the power supply of the computer is working properly, and the data cable is reconnected to the scanner again.

Fault 3: After connecting the serial port line, there is no data transmission for code readingSolution: It may be that the serial port mode is not set or the communication protocol is wrong. To set the scanning serial mode to serial mode, reset it to the correct communication protocol.

Fault 4: Crash after scanning a barcode or the computer display cannot recognize the USB device when using the USB cableSolution: It may be that the data cannot be transmitted due to the poor cable and the USB device is defective. You need to find a dealer to purchase a replacement cable.

Fault 5: The scanning is normal, and the keyboard cannot be usedSolution: It may be that the internal IC of the scanner is bad and burned. It needs to be returned to the manufacturer for repair.

Fault 6: Laser always-on solution: It may be that the manual is scanned and the barcode is set to always-on mode. It needs to be restored to factory settings and returned to the manufacturer for repair.

Fault 7: There is no prompt sound after power-on, and there is no light when pressing the buttonSolution: It may be that the power supply of the scanner is not on, the scanner is not powered on, or the data cable interface has been loosened, and the contact is poor. You need to check the scanner cable to make sure that the computer is powered properly and that the data cable is reconnected to the scanner.
