What to do if the Symbol Barcode Reader trigger is not working?
If nothing happens when you pull the trigger of your Symbol Barcode Reader, it could be due to a lack of power or loose cable connections. First, check the system power and ensure the power supply is connected if your configuration requires one. Then, check all cable connections to make sure they are secure.
Why does the laser on my Symbol LS 4208 turn on, but it won't decode the symbol?
If the laser on your Symbol Barcode Reader is on but failing to decode, there are several potential causes. The scanner may not be programmed for the correct bar code type, the bar code symbol may be unreadable because it is defaced, or the distance between the scanner and the bar code might be incorrect. First, check the symbol to ensure it is not defaced and try scanning test symbols of the same bar code type. Then move the scanner closer to or further from the bar code.
How to fix incorrectly displayed scanned data from Symbol LS 4208 on the host?
If scanned data is incorrectly displayed on the host, the Symbol Barcode Reader might not be properly programmed to work with the host. Ensure the proper host is selected and check the scanner's host type parameters or editing options. If using RS-232, ensure the scanner’s communication parameters match the host’s settings. For a keyboard wedge configuration, make sure the system is programmed for the correct keyboard type and that the CAPS LOCK key is off. Also, verify that editing options, like UPC-E to UPC-A conversion, are correctly programmed.
What to do if Symbol LS 4208 decodes a symbol but does not transmit it to the host?
If your Symbol Barcode Reader decodes a symbol but doesn't transmit it to the host, it might not be programmed for the correct host type. You should scan the appropriate host type bar code to resolve this issue.
What to do if my Symbol LS 4208 Barcode Reader emits laser but doesn't decode?
If your Symbol Barcode Reader emits the laser but fails to decode, there are several possible reasons. First, the scanner might not be programmed to read the specific type of bar code you are scanning; in this case, program the scanner to read that type of bar code. Second, the bar code symbol itself might be unreadable, so try scanning test symbols of the same bar code type. Third, the distance between the scanner and the bar code may be incorrect; adjust the distance by moving the scanner closer to or further from the bar code. Finally, the scan line might not be crossing every bar and space of the symbol; adjust the symbol's position until the scan line is within the acceptable aiming pattern.
