Chapter 3: Getting To Know Your 8525/8530
Scan LED Indicators
3.7.2 Scan LED Indicators
The 8525/8530 scanner LED (the upper-right LED) indicates whether or not your
scan is successful. Keep in mind that scan indicators only function when using a
non-decoded 1D laser scanner connected to the tether port. All other external
scanners have integrated LED indicators that are not controlled by the 8525/8530.
The LED behaves as follows:
• Scan In Progress: scan LED displays solid red colour.
• Successful Scan: scan LED displays solid green colour and turns off when
the scan is ended.
• Unsuccessful scan: scan LED flashes red.
A bar code icon appears on the screen during a scan. While the scanner beam is
active, the onscreen message states – SCANNING. If the scan is successful, the bar
code data is displayed on the screen until the scan trigger is released.
3.7.3 Troubleshooting
If the scanner is not working, investigate the following:
• Is the 8525/8530 on?
• Check that the bar code symbology being scanned is enabled for the
8525/8530 you are using. Check any other parameters that affect the scan-
ning 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 vehicle-mount display the warning without scanning? This sug-
gests a hardware problem in the 8525/8530.
• Is the laser beam scanning across the bar code?
• Once the scan beam has stopped, check the scanner window for
dirt or fogging.
