Event Reporting
LXE mobile devices with integrated scanners aren’t designed to process events triggered by the
integrated scan engine. Events are processed by the operating system resident on the mobile device.

Factors That May Impact Scanner Performance
The range of a scanner is dependent upon many outside influences including size of the barcode,
quality of the barcode printing, material the barcode is printed on, condition of the scan lens
(scratches) and angle of the scanner endcap relative to the barcode label. Any of these factors may
result in having to re-scan the label from a different distance or angle.

result in having to re-scan the label from a different distance or angle.
Barcode Quality
Check the barcode for marks or physical damage e.g. ripped label, missing section, correct size for
the scanner being used, etc.
the scanner being used, etc.
In general, the bigger the barcode the further the distance from which it can be read. If the barcode is
smaller than the specified size for the scanner being used, the distance, in almost all cases, will shrink.

Large barcodes can be scanned at the maximum distance. Hold the scanner closer to small barcodes
(or with bars that are very close together).
(or with bars that are very close together).
Note: Do not position the scanner exactly perpendicular to the barcode being scanned. In this
position, light can bounce back into the scanner’s exit window, and possibly prevent a
successful decode.
successful decode.
Barcode Symbology
Barcodes such as UPC codes and Code 128 are more complex than Code 39 and Interleaved 2 of 5.
When attempting to get the maximum read distance possible, particularly with reflective labels, use
Code 39. The use of Code 128 or other more complex symbologies will almost always result in a
reduction in maximum read distance. LXE will not support scanner maximum distances when
symbologies other than Code 39 are used.

Lens Damage
A scratched scanner aperture can impact read rates and distances. Scanner apertures should be
inspected frequently, particularly if scanning quality or distances get worse over time.
