Honeywell Xenon 1900 Barcode Scanner: Transparent... | terminalfaults.org

Technical Background:

Barcode scanners use a laser or LED to illuminate the barcode, and a sensor to detect the reflected light. Transparent materials allow light to pass through, reducing the amount of reflected light and decreasing the contrast between the bars and spaces. This can result in insufficient signal strength for the sensor to decode the barcode correctly. Ambient lighting interference can further exacerbate the problem. Additionally, the scanner's firmware may not be optimized for decoding low-contrast barcodes, or the scanner's configuration may not be set correctly for handling these types of materials.

Symptoms:

The Honeywell Xenon 1900 barcode scanner fails to consistently or accurately read barcodes printed on transparent or semi-transparent materials. The device may successfully scan opaque barcodes, but struggles with those on clear surfaces.

Possible Causes:

Insufficient contrast between the barcode and the transparent material.
Ambient light interference causing glare or washing out the barcode.
Incorrect scanner configuration settings for transparent barcodes.
Laser or LED diode degradation, resulting in reduced light output.
Sensor sensitivity issues or calibration drift within the scanner.
Damaged or dirty scanner window affecting light transmission.

Solution:

1

Ensure the scanner window is clean and free from smudges or scratches. Use a clean, dry, lint-free cloth to wipe the window.
2

Adjust the ambient lighting in the scanning area to minimize glare and reflections. Experiment with different lighting angles and intensities.
3

Verify the scanner configuration settings. Consult the Honeywell Xenon 1900 user manual to ensure that the scanner is configured to read barcodes on transparent materials. Check settings related to symbology, contrast, and gain.
4

Increase the scanner's gain or sensitivity settings within the scanner's configuration utility. Refer to the Honeywell Xenon 1900 programming guide.
5

Test the scanner with a variety of transparent barcodes to determine if the problem is specific to certain materials or barcode types.
6

Reseat the scanner's cable connections at both the scanner and host device to ensure a secure connection.
7

If possible, test the scanner with a known-good cable to rule out cable issues.

Safety Warning:

Safe Handling: Always unplug the scanner from the host device before performing any cleaning or maintenance procedures. Avoid using excessive force when handling the scanner or cables. Static discharge (ESD) is a potential hazard, especially in dry environments. Ground yourself by touching a grounded metal object before handling the scanner.

Prevention:

Regularly clean the scanner window with a clean, dry, lint-free cloth.,Implement cable strain relief measures to prevent damage to the scanner cable.,Avoid exposing the scanner to extreme temperatures or humidity.,Periodically check the scanner's configuration settings to ensure they are optimized for the scanning environment.,Provide adequate ambient lighting in the scanning area.,Train staff on proper scanner handling and maintenance procedures.

Expert Tip:

Some Honeywell scanners have a 'Presentation Mode' which can interfere with transparent barcodes. Try toggling this mode OFF using the configuration utility or a programming barcode found in the user manual. A slight angle adjustment during the scan can also sometimes improve the read rate on reflective surfaces.

Frequently Asked Questions

•What are the optimal configuration settings for scanning transparent barcodes with the Xenon 1900?

Refer to the Honeywell Xenon 1900 user manual or programming guide for specific configuration options. Look for settings related to symbology, contrast, gain, and decoding algorithms.

•How can I reduce ambient light interference in the scanning area?

Adjust the lighting angle and intensity. Consider using shades or blinds to block direct sunlight. Ensure that the barcode is not reflecting light directly into the scanner's sensor.

•What type of cleaning solution is safe to use on the scanner window?

Generally, a clean, dry, lint-free cloth is sufficient. If necessary, use a slightly damp cloth with distilled water. Avoid using harsh chemicals or abrasive cleaners.
