Dead Zone
When scanning a 1-D bar code, there is only a small specular dead
zone to avoid (+2_ from the direct laser beam). The specular dead
zone is larger when scanning PDF417 (+9_ from the direct laser
beam). At the same time, the scanner is not effective if its beam hits
the bar code’s surface at an angle greater than 30_ from normal to
that surface.

You can also scan successfully by tilting the scanner forward from
parallel about 20_ to 50_ toward the scanning surface.
