Reading Techniques

The engine projects a bright red scan beam that corresponds to the engine's
scanning field of view. The scan beam should be centered horizontally over
the bar code and must highlight all the vertical bars of the bar code. It will not
read if the scan beam is in any other direction.
Good Read
The scan beam is smaller when the engine is closer to the code and larger
when it is farther from the code. Symbologies with smaller bars or elements
(mil size) should be read closer to the unit. Symbologies with larger bars or
ele-ments (mil size) should be read farther from the unit. To read a symbol (on
a page or on an object), hold the engine at an appropriate distance from the
tar-get and center the scan beam on the symbol. If the code being scanned is
highly reflective (e.g., laminated), it may be necessary to tilt the code up 15° to
18° to prevent unwanted reflection.
Note: At 254mm a double beam of up to 3mm is to be expected. A double
beam will not affect scanning performance and is not a product defect.
