Why does my host display scanned data incorrectly from Symbol Barcode Reader?
- D
  Dana BrooksAug 30, 2025
  If the host displays scanned data incorrectly from your Symbol Barcode Reader, ensure the proper host is selected by scanning the appropriate host type programming bar code. For RS-232 connections, verify that the scanner’s communication parameters match the host’s settings by checking the scanner’s host type parameters or editing options. For USB HID keyboard or Keyboard Wedge configurations, ensure the system is programmed for the correct keyboard type and language, and turn off the CAPS LOCK key. Also, ensure editing options (e.g., ADF, UPC-E to UPC-A Conversion) are properly programmed.

Why does my Symbol Barcode Reader LED indicate a battery temperature fault?
- C
  cshortAug 28, 2025
  The LED indicates a battery temperature fault because the battery is above or below normal operating temperature. Do not use the scanner and move it to a location within normal operating temperature. The scanner can remain in the cradle while the battery warms or cools to normal operating temperature.

How to fix a Symbol Barcode Reader when the laser comes on, but symbol does not decode?
- C
  Christopher RiggsAug 27, 2025
  If the laser comes on but the symbol doesn't decode, consider the following: * Ensure the scanner is programmed to read the type of bar code you are scanning. * Check the symbol to ensure it is not defaced. Try scanning test symbols of the same bar code type. * Adjust the distance between the scanner and the bar code by moving the scanner closer or further away.

What to do if nothing happens when the trigger is pulled on my Symbol LS4278?
- K
  Kathryn NelsonAug 27, 2025
  If nothing happens when you pull the trigger, it could be due to a few reasons: 1. The battery may be discharged, so charge the scanner in the cradle. Also, check that the battery door is closed and the end cap to the battery chamber is secured. 2. The scanner might be disabled. Some host interfaces (e.g., Synapse, IBM-468x) can disable the scanner. If this applies, enable the scanner via the host interface.

Why is scanned data incorrectly displayed on the host using Symbol LS4278 Barcode Reader?
- H
  Hannah WebbAug 26, 2025
  If scanned data is incorrectly displayed, ensure the correct host is selected and check the scanner’s host type parameters or editing options. For RS-232, ensure the scanner’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. Also, verify that editing options such as UPC-E to UPC-A conversion are properly programmed.

What to do if Symbol Barcode Reader decodes but doesn't transmit data?
- R
  Robert SanchezAug 25, 2025
  If your Symbol Barcode Reader decodes the bar code but fails to transmit the data to the host, verify that the scanner is programmed for the correct host type by scanning the appropriate programming bar code. Also, ensure all cable connections are secure. Check that the cradle is programmed for the correct host interface by reviewing the scanner host parameters or editing options. If using a cradle, ensure the scanner is paired by scanning the PAIR bar code on the cradle. If the cradle has lost connection to the host, disconnect the power supply and host cable, wait three seconds, then reconnect the host cable and power supply, and reestablish pairing.
