DS3678 Digital Scanner
The cordless DS3678 combines superior 1D and 2D omnidirectional barcode scanning performance and
advanced ergonomics in a lightweight design. See the DS36X8 Product Reference Guide for more
information.

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.
Scanning with Internal Imager
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.
