Unsuccessful Scan
When the scan is unsuccessful, the Scan LED remains red until the 10 second timeout occurs or
the Scan key/trigger is released. The currently running application may produce distinctive
audible tones. Check the following:
•
Check the barcode for marks or physical damage e.g. ripped label, missing section, etc.
•
Try scanning test symbols of the same code type at different distances and angles.
•
Is the imager aperture unscratched and unsoiled?
Aiming the Barcode Imager
Aim the imager away from you, direct it at the barcode and press the trigger or button (as
applicable) to scan. The Scan LED (scan indicators are located above the display) turns red to
indicate the imager is on.
Adjust the aim so that the green aiming beam is centered on the barcode.
The red light emitted from the imager must cover every bar and space on the barcode.
When scanning a 2D Matrix barcode, the scan beam must cover the entire barcode.

Make sure the barcode is within the scanning range.
The range of a imager is dependent upon many outside influences including size of the barcode,
quality of the barcode printing, material the barcode is printed on, and angle of the imager beam
relative to the barcode label. Any of these factors may result in having to re-scan the label from a
different distance or angle.
