The solution of bar code scanner unable to scan

The solution of bar code scanner unable to scan

One factor: the wire barcode scanner has light but can't scan.


1) The scanning gun of PS / 2 is connected to the mouse port.
2) The PS / 2 scan gun is correctly connected to the keyboard port, the scan gun is not connected to the PS / 2 keyboard, and the scan gun is not adjusted to the PS / 2 keyboard mode.
3) The scan gun of PS / 2 is connected to the conversion line from USB to PS / 2, but the chip of the conversion line is not good, so it is often unable to scan or encode incorrectly.
4) The scanning time mark is not in the scanning area. During the scanning process, the computer occasionally pops up a window and changes the position of the cursor.
5) Do not turn off the input method while scanning, which may cause scan failure or error code.
6) Scan code system does not open, all code switches can be opened
7) When scanning barcode, the distance is too far or too close, and the angle is too large.
8) Serial number and baud rate are not set in the serial gun.
9) Incomplete or severely damaged scanning barcode
10) Direct sunlight or too strong light, scanning gun cannot scan
11) There is a problem with the interface transmission. The interface may be broken, and the scanning gun line may be broken.
Scan barcode too far or too close, angle too large
13) Serial number and baud rate are not set in serial gun.
14) Scanning cannot be a very fine barcode. Generally, the scanning accuracy of cable scanning gun is more than 5ml. If your barcode is less than 5ml, please select 3ml cable scanning gun.


On the other hand:


1) The cable of the scan gun is not connected.
2) The lead of the wired scanning gun is not connected to the computer.
3) The power supply of the computer is insufficient, which makes the scanning gun unable to work
4) Whether the USB port and PS / port of the computer are normal
5) The cable of the scanning gun is broken
6) The bare head or main board of the wired scanning gun is broken
