Mount and Position the Reader
- Position the reader several inches from the symbol. You may need
to reposition the reader a few times to find the ideal distance.
- Tip the reader relative to the symbol to avoid the glare of direct
(specular) reflection.
- Symbols can be rotated (tilted) at any angle; however, for best
results symbols should be aligned with the field of view. In the case
of linear symbols, aligning the bars in the direction of their movement
(ladder orientation) will minimize the chances of blurring and will
result in more consistent decodes.
- Important:
Avoid excessive skew or pitch. Maximum skew is ±30°;
maximum pitch is ±30°.
The illustration below shows approximate skew axis, pitch axis, and
tilt axis.
