39 T ROUBLESHOOTING The following guide is for reference purpos es only. Contact a Metrologic representative at 1-800-ID-MET RO or 1-800-436- 3876 to preserve the limited warranty terms . Symptom Possible Cause(s) Solution All Interfaces No LED, beep or motor spin.
40 T ROUBLESHOOTING Symptom Possible Cause(s) Solution All Interfaces The print quality of the bar code is suspect. Check the character length lock. Scanner beeps at some bar codes and NOT form others of the same bar code symbology. The aspect ratio of the bar code is out of tolerance.
41 T ROUBLESHOOTING Symptom Possible Cause(s) Solution RS232 Only The host is receiving data but the data does not look correct. The scanner and host may not be configured for the same interface. Check that the scanner and the host are configured for the same interface.
