3.7.3 Troubleshooting
If the scanner is not working, investigate the following:
• Is the 7530 on?
• Check that the bar code symbology being scanned is enabled for the 7530
you are using. Check any other parameters that affect the scanning proce-
dure 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 7530.
• Is the laser beam scanning across the bar code?
• Once the scan beam has stopped, check the scanner window for
dirt or fogging.
3.7.4 Operating One Dimensional (1D) Internal Laser Scanners
• Turn the 7530 on. Wait until the unit has booted up completely.
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 120 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.
• 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.
