Position the Imager

Step 3 — Position the Imager

• Position the imager at a focal distance of one inch or more from a test symbol.

• Tip the imager relative to the symbol if necessary 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 skew axis, pitch axis, and tilt axis.
