3.4 POSITIONING
The DS5100 scanner is able to decode moving barcode labels at a variety of angles,
however significant angular distortion may degrade reading performance.
When mounting the DS5100 take into consideration these three ideal label position angles:
Skew 15° to 30°, Tilt 0° and Pitch 0°.
Follow the suggestions for the best orientation:
The Skew angle is represented by the value S in Figure 29. Position the reader to assure at
least 15° for the Skew angle. This avoids the direct reflection of the laser light emitted by the
DS5100.
Figure 29 – DS5100 Skew Angle
The Tilt angle is represented by the value T in Figure 30. Position the reader in order to
minimize the Tilt angle.

By using the ACR4 (Advanced Code Reconstruction) software parameter, the tilt angle is
less critical and can be decoded even if the scan line doesn’t cross the entire code.
