Troubleshooting
If the scanner is not working, investigate the following:
•
Is the unit on?
•
Check that the bar code symbology being scanned is enabled for the hand-held you are
using. Check any other parameters that affect the scanning procedure or the bar code.
•
Check the bar code to make sure it is not damaged. Try scanning a different bar code to
verify that the problem is not with the bar code.
•
Check that the bar code is within the proper range.
•
Does the hand-held display the warning without scanning? This suggests a hardware
problem in the hand-held.
•
Is the laser beam scanning across the bar code?
•
Once the scan beam has stopped, check the scanner window for dirt or fogging.

Operating One Dimensional (1D) Internal Laser Scanners
•
Turn the hand-held on. Wait until the unit has booted up completely.
•
Aim at the bar code and press the scan key or the trigger. A scan beam and a warning
indicator appear until a successful decode is achieved or six seconds have elapsed.

Operating Internal Two Dimensional (2D) Imagers
An imager scanner takes a snap shot of a single bar code or multiple bar codes (at one time).
It can find a bar code regardless of its orientation—that is, even a bar code printed at a 45
degree angle to the hand-held will be decoded successfully.
Important: If an aiming dot is available on the installed scanner, the dot will be enabled
for a configurable time period (including off), after which normal scanning
begins. Refer to “Dot Time (msec)” on page C-7 for details.
Double-clicking the trigger will override the aiming delay and initiate an
immediate scan. Note that the aiming dot is standard on long-range and
high visibility internal scanners.
