Scanning
The MC3300ax offers the following data capture options:
• SE4770 1D/2D
• SE4850-ER 1D/2D
Refer to the MC3300ax Mobile Computer Product Reference Guide for other scanning options.
Scanning with Internal Imager
Use the internal imager to capture barcode data.
NOTE: To read a barcode, a scan-enabled app is required. The device contains the DataWedge app that
allows the user to enable the imager, decode the barcode data, and display the barcode content.
To scan with the internal imager:
1. Ensure that an app is open on the device and a text field is in focus (text cursor in text field).
2. Point the exit window on the top of the device at a barcode.
3. Press and hold the scan button or trigger.
The red laser aiming pattern turns on to assist in aiming.
4. Ensure the barcode is within the area formed by the cross-hairs the aiming pattern. The aiming dot
increases visibility in bright lighting conditions.
Figure 5 Aiming Pattern: Standard and Extended Range
NOTE: When the device is in Pick List Mode, the device does not decode the barcode until the center of
the cross-hair touches the barcode.
Figure 6 Pick List Mode with Multiple Barcodes in Aiming Pattern: Standard and Extended Range
The Scan LEDs light green and a beep sounds, by default, to indicate the barcode was decoded
successfully.
5. Release the scan button or Trigger.
The barcode content data appears in the text field.
