Xenon 1900 Barcode Scanner: Underwater Use Diagnostic... | terminalfaults.org

Technical Background:

The Xenon 1900 is designed for optical barcode scanning in air. Submersion in water affects the refractive index between the scanner lens, the barcode, and the scanner's sensor. This refractive change causes signal attenuation and distortion of the reflected light, impacting decoding performance. Ambient light scattering in water further reduces the signal-to-noise ratio.

Symptoms:

Reported failure of the Honeywell Xenon 1900 barcode scanner to successfully read barcodes while submerged in water.

Possible Causes:

Refractive index mismatch between air and water disrupts the scanner's optical path.
Water absorbs and scatters light, reducing the intensity of the reflected barcode signal.
Barcode label degradation or distortion when wet impacts scanning accuracy.
Scanner's optical sensor is not designed for underwater light conditions.
Potential for internal short circuit if water ingress occurs, although the device is not rated for underwater use.

Solution:

1

Discontinue underwater use immediately. The Xenon 1900 is not designed for this purpose.
2

Safe Handling: Disconnect the scanner from the power source.
3

Inspect the scanner for any signs of water ingress (condensation, water droplets).
4

If water ingress is suspected, allow the scanner to air dry in a well-ventilated area for a minimum of 24 hours before re-connecting.
5

Clean the scanner lens with a dry, lint-free cloth to remove any water residue or mineral deposits.
6

Test the scanner's functionality in a normal, dry environment with standard barcodes.
7

If the scanner continues to malfunction after drying and cleaning, it requires replacement. Do NOT attempt internal repairs.

Safety Warning:

Using the Xenon 1900 underwater poses a risk of electrical short circuit if water enters the device. Never submerge electrical equipment not specifically designed for underwater use. Static electricity can damage the scanner's components; ground yourself before handling the device, especially in dry environments. Always perform Safe Handling (unplugging) before any cleaning or inspection.

Prevention:

Avoid using the scanner in wet environments or where it may be exposed to water. Store the scanner in a dry location when not in use. Regularly inspect the cable connection for any signs of strain or damage. Clean the lens regularly with a dry, lint-free cloth. Ensure the scanner is securely mounted to prevent accidental drops.

Expert Tip:

If barcodes must be scanned near liquids, consider using a waterproof barcode sleeve or pouch to protect the barcode label itself. This minimizes signal degradation and the need to submerge the scanner. A high-contrast label may also help in some cases.

Frequently Asked Questions

•What is the IP rating of the Xenon 1900?

The Xenon 1900 has an IP41 rating, meaning it is protected against solid objects larger than 1mm and dripping water. It is not waterproof or submersible.

•Can a different barcode scanner be used underwater?

Yes, barcode scanners with a specific IP67 or IP68 rating are designed for underwater use. Consult manufacturers for certified submersible devices.

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

Only use a dry, lint-free cloth to clean the lens. Do NOT use any liquid cleaners, as they may damage the lens coating or internal components.
