Note: A scan distance too close will read a larger than the known X dimension.
Too far will read smaller than the known dimension. The X dimension is

Setting the Proper Scan Angle

The SV Series requires a fixed scanning angle for two basic reasons:
1. To maintain proper scanner signal levels in order to effectively decode
symbols.
2. To accurately calculate reflectance parameters.
Acceptable scanning angles range from 10 to 35 degrees from vertical (relative
to the bar code being scanned) depending on the material being scanned,
mounting considerations, etc.
