Distance from Label
Large barcodes can be scanned at the maximum distance. Hold the scanner closer to small
barcodes (or with bars that are very close together).
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.
NOTE
Successful Scan
When the scan is successful, the scanner's good scan indicator illuminates, the scan on
indicator is off, and the currently running application may produce a distinctive audible tone.
Unsuccessful Scan
When the scan is unsuccessful, the scan on indicator remains illuminated and the currently
running application may produce distinctive audible tones. Check the following:
•
Is the scanner programmed for the barcode being read?
•
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.
Cleaning the Scanner Aperture
Keep fingers and rough or sharp objects away from the scan aperture.
Wipe the scanner window periodically with a damp, soft cloth. Remove lint or foreign material
with clean, filtered canned air.
Do not scrub optical surfaces, clean only those areas which are soiled.
Do not pour, spray, or spill any liquid on the scanner. The Barcode Scanner contains the
circuitry, scanning motor and laser. Handle with appropriate care.
