Data Capture
The device supports data capture using:
• integrated camera
• SE4750 Expansion Back
• RS507 and RS507X Hands-free Imager
• RS6000 Ring Scanner
• DS3608 and DS3678 scanners
• DS2278 scanner.
Imaging
The imager uses imaging technology to take a picture of a bar code, stores the resulting image in its memory,
and executes state-of-the-art software decoding algorithms to extract the bar code data from the image.
The device with a 2D imager has the following features:
• Omnidirectional reading of a variety of bar code symbologies, including the most popular linear, postal,
PDF417, and 2D matrix code types.
• Advanced intuitive laser aiming cross-hair and dot aiming for easy point-and-shoot operation.
Scanning Considerations
Typically, scanning is a simple matter of aim, scan, and decode, with a few quick trial efforts to master it.
However, consider the following to optimize scanning performance:
• Range: Scanners decode best over a particular working range — minimum and maximum distances from
the barcode. This range varies according to barcode density and scanning device optics. Scan within range
for quick and constant decodes; scanning too close or too far away prevents decodes. Move the scanner
closer and further away to find the right working range for the barcodes being scanned.
• Angle: Scanning angle is important for quick decodes. When the illumination/flash reflects directly back into
the imager, the specular reflection can blind/saturate the imager. To avoid this, scan the barcode so that the
beam does not bounce directly back. Do not scan at too sharp an angle; the scanner needs to collect
scattered reflections from the scan to make a successful decode. Practice quickly shows what tolerances to
work within.
• Hold the device farther away for larger symbols.
• Move the device closer for symbols with bars that are close together.
NOTE: Scanning procedures depend on the app and device configuration. An app may use different scanning
procedures from the one listed above.
