Honeywell Xenon 1900 Barcode Scanner Diagnostic Report:... | terminalfaults.org

Technical Background:

Barcode scanners operate by emitting a light beam and analyzing the reflected light pattern. Reflective surfaces can cause excessive light reflection, saturating the scanner's sensor and preventing accurate barcode decoding. Environmental factors such as ambient light, power supply fluctuations affecting the scanner's internal voltage regulation, and electrostatic discharge (ESD) events can also contribute to scan failures. Signal attenuation along the data cable can degrade data transmission between the scanner and the host system.

Symptoms:

The Honeywell Xenon 1900 barcode scanner fails to reliably read barcodes, specifically those printed on reflective labels. The reported issue indicates a possible 'glare' interference.

Possible Causes:

Excessive ambient light interfering with the scanner's sensor.
Scanner sensor saturation due to highly reflective barcode labels.
Power supply voltage fluctuations causing inconsistent scanner operation.
Electrostatic discharge (ESD) events affecting the scanner's electronic components.
Data cable damage or loose connection resulting in signal degradation.
Accumulation of dust or debris on the scanner lens or barcode labels.

Solution:

1

Adjust ambient lighting in the scan area to minimize direct reflections on barcode labels. Consider repositioning light sources or using diffusers.
2

Clean the scanner lens with a clean, dry, lint-free cloth. Do NOT use abrasive cleaners or solvents.
3

Verify the scanner's power supply is providing the correct voltage and current. Use a known good power adapter if available.
4

Inspect the scanner's data cable for any signs of damage (fraying, kinks, or cuts). Replace the cable if necessary.
5

Ensure the data cable is securely connected to both the scanner and the host system. Reseat the connections.
6

Test the scanner with a different type of barcode label (non-reflective) to determine if the issue is specific to reflective labels.
7

If applicable, check the scanner's configuration settings for any options related to reflective barcode scanning or gain adjustment. Consult the Honeywell Xenon 1900 user manual.

Safety Warning:

Handle the Honeywell Xenon 1900 scanner with care to avoid dropping or damaging it. Static electricity can damage the scanner's internal components. Discharge static electricity before handling the scanner by touching a grounded metal object. To prevent electrical shock, unplug the scanner from the power source before cleaning or performing any maintenance. Safe Handling: Unplug the device from the power source before cleaning.

Prevention:

Regularly clean the scanner lens with a clean, dry, lint-free cloth.,Implement cable management practices to prevent cable strain and damage.,Use anti-static mats in the checkout area to minimize electrostatic discharge (ESD) events, especially during dry winter months.,Ensure proper grounding of all electronic equipment in the checkout area.,Periodically inspect the scanner's data cable for any signs of wear or damage.

Expert Tip:

Try adjusting the scanner's 'Picklist' setting. If enabled, the scanner may be struggling to differentiate between multiple barcodes. Disabling it might improve performance on single, reflective barcodes.

Frequently Asked Questions

•Is the scanner connected directly to the host system or through a USB hub?

Connecting through a USB hub can sometimes cause power or data transmission issues. Try connecting directly to the host.

•What type of barcodes are failing to scan (e.g., Code 128, QR Code)?

Knowing the barcode type can help determine if the issue is related to a specific symbology or scanner configuration setting.

•Has the scanner recently been relocated or exposed to any unusual environmental conditions (e.g., excessive heat or humidity)?

Environmental factors can sometimes affect scanner performance.
