Scan
The Imager uses digital camera technology to take a picture of a barcode and
software decoding algorithms are executed to extract the barcode data from the
image.
Scan Triggering Modes
Manual Triggering (Triggered models only)
1. Launch a scanning software application on the mobile computer or WT4090.
2. Press the Scan Trigger and position the aiming cross hair laser to cover the
barcode. The Imager takes a digital picture (image) of the barcode and stores it
in memory for decoding.
3. One green flash and a high beep sounds to indicate that the barcode was
properly decoded.
NOTE In some configurations proper decoding of a barcode is indicated by
software application running on mobile computer or WT4090.
Auto-triggering (Triggered models only)
The Imager is provided with auto-triggering capability.
In auto-triggering mode, both motion and proximity sensors are used to trigger the
Imager when the user intends to scan a barcode.
With auto-triggering activated, the Imager automatically scans when motion stops
and a barcode is placed within the depth of field of the Imager. The Imager scans
the barcode and turns off to conserve power.
To scan barcode in auto-triggering mode:
1. Bring the Imager within 9 inches ± 1 inch (22.86 cm ± 2.54 cm) of a barcode
label.
2. Hold the Imager steady, aiming at the barcode label.
3. The Imager takes a picture (image) of the barcode and stores it in memory for
decoding.
4. One green flash of the Scan LED and a high beep indicates that a barcode was
properly decoded.
NOTE In some configurations, proper decoding of a barcode is indicated by a
software application running on mobile computer or WT4090.
