What does it mean when Symbol Barcode Reader emits high/high/high/low beeps?
High/high/high/low beeps from your Symbol Barcode Reader indicate an RS-232 receive error, which is normal during host reset. Otherwise, set the scanner's RS-232 parity to match the host setting.
What does it mean when my Symbol Barcode Reader emits low/high/low beeps?
Low/high/low beeps from your Symbol Barcode Reader can indicate an ADF transmit error or an invalid ADF rule is detected.
Why does my Symbol LS4278 emit five long low beeps after decoding?
Five long low beeps after a bar code is decoded indicate a conversion or format error. This means the scanner’s conversion parameters are not properly configured, or an ADF rule was set up with characters that can't be sent for the host selected, or a bar code was scanned with characters that can't be sent for that host. Ensure the scanner’s conversion parameters are properly configured. Change the ADF rule, or change to a host that can support the ADF rule. Change the bar code, or change to a host that can support the bar code.
What to do if symbol is decoded but not transmitted to the host using Symbol Barcode Reader?
If the decoded symbol isn't being transmitted to the host, consider these potential solutions: * Verify that the cradle is programmed for the correct host interface. * Pair the scanner to the cradle using the PAIR bar code on the cradle. * Ensure all cable connections are secure. * If the cradle has lost connection to the host, disconnect the power supply, then the host cable, wait three seconds, reconnect the host cable, reconnect the power supply, and reestablish pairing.
What does it mean when Symbol Barcode Reader emits high/low beeps?
High/low beeps from your Symbol Barcode Reader typically indicate the scanner is buffering Code 39 data or a keyboard parameter is selected, which is normal. Alternatively, if there is a Bluetooth disconnection event, move the scanner back into range of the remote device. In Master (SPP/HID) mode, re-pair the scanner and cradle by scanning the PAIR bar code on the cradle and check cradle power. In Slave (SPP/HID) mode, reestablish the connection between the scanner and remote device from the remote device side.
What does it mean when my Symbol Barcode Reader emits long low/long high beeps?
Long low/long high beeps from your Symbol Barcode Reader indicate an input error, meaning an incorrect bar code or Cancel bar code was scanned; scan the correct numeric bar codes within range for the parameter programmed. This beep sequence can also indicate a page timeout, meaning the remote device is out of range or not powered; move the scanner back into range of the remote device, try to reconnect, and check the remote device configuration.
Why doesn't the laser appear when I pull the trigger on my Symbol LS4278 Barcode Reader?
If the laser does not appear when the trigger is pulled on your Symbol Barcode Reader, check the system power and reconnect the power supply if needed. Ensure the correct host interface cable is used. Also, check for loose cable connections and re-connect them.
Why does Symbol LS4278 emit four long low beeps?
Four long low beeps from your Symbol Barcode Reader indicate a transmission error was detected in a scanned symbol, and the data is ignored. This often occurs if the unit is not properly configured, so check the option settings. It can also mean the scanner is out of range, not paired to the cradle, or not connected to a remote Bluetooth device; move the scanner back into range or scan the PAIR bar code on the cradle. This beep sequence can also mean the cradle did not receive transmitted data; check the host system for receipt of transmitted data, and if it was not received, re-scan the bar code.
What to do if nothing happens when trigger is pulled on Symbol Barcode Reader?
If nothing happens when you pull the trigger on your Symbol Barcode Reader, check the system power and reconnect the power supply if required. Inspect the interface/power cables for loose connections and re-connect them. If using Synapse or IBM-468x mode, enable the scanner via the host interface. Also, ensure that the end cap to the battery chamber is secured.
How to fix Symbol LS4278 Barcode Reader when it emits laser but doesn't decode?
If your Symbol Barcode Reader emits the laser but does not decode the bar code, ensure the scanner is programmed for the correct bar code type. If the bar code symbol is unreadable, scan test symbols to check if the bar code is defaced. Adjust the distance between the scanner and the bar code, and ensure the scan line crosses every bar and space of the symbol by adjusting the symbol's position.
