Troubleshoot USB Barcode Scanners

  • Clear the USB accessory port of debris and dust.

  • Plug the barcode scanner into a different port on the USB accessory hub.

Note: If you are having trouble pulling up your onscreen keyboard, double click the power button on the scanner.

  1. Print the Quick Start Guide.

  2. Under SET DEFAULTS, scan the barcode labeled RETURN TO FACTORY DEFAULTS while your barcode scanner is connected to your device.
