POSITIONING

The scanner must be positioned so that the laser beam is aligned to completely
intersect the codes passing in front of it. This positioning must also be within its
reading distance (see par. 3.4).
The DS1100 scanner is able to decode barcode labels at a variety of angles,
however significant angular distortion may degrade reading performance. When
mounting the DS1100 take into consideration these three ideal label position angles:
Pitch 0°, Skew 15° to 30° and Tilt 0°.
Follow the suggestions for the best orientation:
The Pitch angle is represented by the value P in Figure 14. Position the reader in
order to minimize the Pitch angle.

The Skew angle is represented by the value S in Figure 15. Position the reader to
assure about 15° for the Skew angle. This avoids the direct reflection of the laser
light emitted by the DS1100.
For the raster version, this angle refers to the most inclined or external raster line, so
that all other raster lines assure more than 15° Skew.
For the skew angle value with DS1100 90° versions, refer to par. 2.2.2.
