3.5 POSITIONING
The DS2400N scanner is able to decode moving barcode labels at a variety of
angles, however significant angular distortion may degrade reading performance.
When mounting the DS2400N take into consideration these three ideal label position
angles:
Pitch 0°, Skew 10° to 30° and Tilt 0° .
Follow the suggestions for the best orientation:
The
Pitch angle is represented by the value P in Figure 32. Position the reader in
order to minimize the Pitch angle.

The
Skew angle is represented by the value S in Figure 33. Position the reader to
assure at least 10° for the Skew angle. This avoids the direct reflection of the laser
light emitted by the DS2400N.
For the raster version, this angle refers to the most inclined or external raster line, so
that all other raster lines assure
more than 10° Skew.
