Scanning with the Internal Imager

To read a barcode, a scan-enabled application is required. The device contains the DataWedge application, which allows you to enable the imager, decode the barcode data, and display the barcode content.
  1. The SE55 displays a green dash-dot-dash aimer. The SE4770 imager displays a red crosshair aimer.
  2. Ensure that an application is open on the device and a text field is in focus (text cursor in text field).
  3. Point the exit window on the top of the device at a barcode or QR code.
  4. Press and hold the scan button.
    The device projects the aiming pattern.

  5. Imager decoding usually occurs instantaneously. When the device is in Picklist mode, the imager does not decode the barcode until the red crosshair or green dash-dot-dash touches the barcode.
  6. Ensure that the barcode is within the area formed in the aiming pattern.

    The Data Capture LED lights green, and the device beeps, by default, to indicate that the barcode or QR code was decoded successfully.
    The device repeats the steps required to take a digital picture (image) of a poor or difficult barcode as long as the scan button remains pressed.
  7. Release the scan button.
    The device displays the barcode or QR code data in the text field.
