Appendixd Barcodes; Introduction; Troubleshooting; Printing Barcodes In This Guide - LXE MX3-CE Reference Manual

Introduction

This guide contains all the scanner programming barcodes supported by LXE for the MX3-CE
mobile device with an SE923 scanner engine. The SE923 was replaced by the SE955 in July
2006. The SE923 scanner engine is obsolete. The MX3-CE mobile device is obsolete as of June
2005.

Factors That May Impact Laser 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.

Barcode Quality

Check the barcode for marks or physical damage e.g. ripped label, missing section, correct size for
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).

Appendix D Barcodes
Barcodes on the printed page are too compact to be scanned,
especially with a long range scanner.
There is a difference between laser printer types and how they handle some Adobe
Acrobat print functions – specifically, the "shink to fit" option on the Print Options
screen.
Before clicking Print, make sure the "Shrink oversized pages to paper size"
checkbox is unchecked. If the barcode is still too small to be read by the scanner
engine, run the printed page through the laser printer again using the laser printer's
Zoom feature until the barcode is large enough to scan satisfactorily.
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.
