Problem 1. When the scanner scan the barcode, the buzzer sounds normally, but no data transmission
Reason: The reasons for this problem may be the scanner’s scanning settings are incorrect, resulted no data transmission on scanner, another reason may be the failure of wire cable transmission, which leads to no data transmission.
Solution: You can refer to the manual reset the scanner to ensure that the corresponding data line settings are correct.
Problem 2. The scanner serial cable is connected, but no data transmission when reading
Reason: The reasons for this problem may have two, one is probably not set scanner’s serial mode, and the second may be a communication protocol error.
Solution: According to the instructions, the scanner is setted to serial mode, and ensure proper communication protocol.
Problem 3. When the scanner scans, LED does not light, and there is no buzzer sound, no laser.
Reason: Such a situation may be the scanner power is not turned on, or data line interface is not seated tightly, due to poor contact.
Solution: First, check the scanner’s power supply connected, if you ensure the connection, you need to check the data line interface is loose, it is preferable to data lines reconnect scanning gun to ensure normal power use.
Problem 4. The scanner can be a normal use, but no buzzer sound.
Reason: This situation is basically the reason scanner muted.
Solution: Only open the scanner’s buzzer
Problem 5. The scanner starts normally, and there will be a laser, but do not read the code
Reason: The reasons for this problem there are many, the first possibility is a barcode system has been shut down, the second possibility is that the barcode has been corrupted, and the third one may be a barcode print quality problems exist, that the barcode itself quality problems, the fourth one may be the scanner hardware or mainboard failure.
Solution: You can open the corresponding barcode system first, and then check to see if the barcode is damaged, we can also check the printer model.
Problem 6. After the scanner connection is completed, LED flashes, and no sound, can not scan
Reason:This situation is essentially an internal problem with the scanner, are generally poor contact IC.
Solution: In this case you can find auto repair from the distributor.
