What to do if nothing happens when I press the scan trigger on my Symbol LS3478-FZ Barcode Reader?
- T
  Thomas FuentesAug 20, 2025
  If nothing happens when you press the scan trigger on your Symbol Barcode Reader, there might be several reasons: * The scanner may not have power, so check the battery. * Ensure the end cap to the battery chamber is secured. * If the scanner is disabled (for Simple Serial Interface (SSI), Synapse, or IBM-468x mode), enable the scanner via the host interface. Otherwise, you may need to contact support. * If using RS-232 Nixdorf B mode, make sure the CTS line is asserted.

Why is the data not transmitted to the host after decoding the bar code with my Symbol LS3478-FZ Barcode Reader?
- A

  If your Symbol Barcode Reader decodes the barcode but the data isn't transmitted to the host, consider the following: * The scanner may not be paired to the host-connected interface; pair the scanner to the cradle using the PAIR bar code on the cradle. * The cradle may not be programmed for the correct host interface; check scanner host parameters or edit options. * A loose interface cable could be the issue; ensure all cable connections are secure. * The cradle may have lost connection to the host; in this case, disconnect the power supply, disconnect the host cable, wait three seconds, reconnect the host cable, reconnect the power supply, and reestablish pairing.

Why is the scanned data incorrectly displayed on the host from my Symbol LS3478-FZ?

  If scanned data is incorrectly displayed on the host with your Symbol Barcode Reader, it could be due to: * Cradle host communication parameters not matching the host’s parameters; ensure the proper host is selected. * For RS-232, ensure the cradle’s communication parameters match the host’s settings. * For a Keyboard Wedge configuration, ensure the system is programmed for the correct keyboard type, and the CAPS LOCK key is off. * Incorrectly programmed editing options; ensure editing options (e.g., UPC-E to UPC-A conversion) are properly programmed.

What to do if the laser comes on, but my Symbol Barcode Reader does not decode the bar code?
- C
  Charles ReeseAug 27, 2025
  If the laser comes on but your Symbol Barcode Reader doesn't decode the barcode, consider these possibilities: * The scanner might not be programmed for the correct barcode type; ensure it is programmed to read the type of barcode being scanned. * The barcode symbol might be unreadable; check that the symbol is not defaced. Try scanning test barcodes of the same barcode type. * The barcode might be out of range from the scanner; try moving the scanner closer to or further from the barcode.

Why does my Symbol LS3478-FZ Barcode Reader emit four long low beeps after scanning a bar code?
- C
  Claudia HortonAug 28, 2025
  If your Symbol Barcode Reader emits four long low beeps after scanning a barcode, the issue could be: * The cradle has not completed USB initialization; wait several seconds and scan again. * An incorrect host interface cable is being used; ensure that the correct host interface cable is used. * Interface/power cables to the cradle are loose; ensure all cable connections are secure. * The scanner is not paired to a cradle; scan the PAIR bar code on the cradle that is connected to the host that is to receive data. * The scanner has disconnected; refer to the disconnect beep sequence information. * A transmission error was detected; ensure the cradle’s communication parameters match the host's setting.

What does it mean when my Symbol LS3478-FZ Barcode Reader emits a disconnect (short high-short low) beep sequence?
- K
  Kathryn WhiteAug 30, 2025
  If your Symbol Barcode Reader emits a disconnect (short high-short low) beep sequence, this could indicate: * The scanner has disconnected from the cradle because it is too far from the cradle; move closer to the cradle and listen for a reconnection beep (short low-short high). * The scanner has disconnected from the cradle because the cradle has lost power or been placed in USB suspend mode; check power connections to cradle, and if using a USB cable, check to make sure PC has not entered a power save mode.

Why does my Symbol Barcode Reader emit a short low-short high- short low- short high beep sequence while being programmed?
- J
  Joseph FreemanSep 1, 2025
  If your Symbol Barcode Reader emits a short low-short high- short low- short high beep sequence while it is being programmed, it could be due to: * Being out of ADF parameter storage space; erase all rules and reprogram with shorter rules. * Being out of Synapse parameter storage space; scan ’Set Synapse Defaults’ bar code, from the appropriate Synapse Interface Guide, for cables no longer in use and reprogram the scanner for the current host interface.

Why does my Symbol LS3478-FZ make five long low beeps after a bar code is decoded?
- A
  Ana HillSep 5, 2025
  If five long low beeps are heard after a barcode is decoded on your Symbol Barcode Reader, a conversion error or format error has been detected. Ensure the scanner’s conversion parameters are properly configured.

What does it mean if my Symbol LS3478-FZ emits a long low-long high beep sequence during programming?
- R
  Robert HowardSep 7, 2025
  If your Symbol Barcode Reader emits a long low-long high beep sequence during programming, it indicates an input error or that a 'Cancel' barcode was scanned. Ensure that the correct numeric barcodes, that are within range for the parameter being programmed, are being scanned.
