Troubleshoot a Honeywell Xenon 1900 scanner that has stopped decoding QR codes. Focus: decoding library errors, external maintenance, and ESD prevention.
Insufficient power can cause library loading failures.
Software conflicts can interfere with scanner operation.
Ensure the software is configured to accept QR code input.
The Xenon 1900 relies on embedded software libraries to interpret barcode symbologies. A checksum error during boot, firmware corruption, or insufficient power can lead to a failure to load these libraries. Excessive ESD events can corrupt volatile memory. Baud rate mismatch (if applicable to the connection type) can also cause communication failures during library loading.
Honeywell Xenon 1900 scanner fails to decode QR codes. Functionality for other barcode symbologies may be unaffected. The error message indicates a missing decoding library.
Exercise Safe Handling practices when disconnecting and reconnecting the scanner cable. Ensure the area is dry to prevent electrical hazards. Do not attempt to open the scanner casing, as this will void the warranty and may damage the device due to anti-tamper mechanisms. Static electricity can damage the scanner; ground yourself before handling.
Regularly clean the scanner window with a soft, dry cloth to remove dust and debris that may interfere with scanning performance.,Ensure the scanner cable is properly routed and supported to prevent strain or damage.,Implement ESD control measures, such as grounding mats and anti-static wrist straps, particularly in dry environments.,Schedule periodic firmware updates to ensure optimal performance and security.,Avoid exposing the scanner to extreme temperatures or humidity.
If the 'Factory Defaults' barcode fails to resolve the issue, try scanning a 'Configuration Lock' barcode (if enabled) followed by the 'Factory Defaults' barcode. Sometimes configuration locks prevent the scanner from fully resetting. Also, ensure that the QR code symbology is explicitly enabled in the scanner's configuration profile via EZConfig; it may be disabled despite appearing active.
