Honeywell Xenon 1900: Scan Window Cleaning Protocol -... | terminalfaults.org

Technical Background:

The Xenon 1900 scanner utilizes an optical sensor to decode barcodes. Contaminants on the scan window interfere with light transmission and reflection, reducing the signal-to-noise ratio and impacting decoding accuracy. Accumulated dust and residue attenuate the laser diode light, and can create erroneous sensor data. ESD can also affect the scanner's performance.

Symptoms:

Degraded scan performance observed, potentially due to smudges, dust, or residue on the scan window. Impacted barcode readability, increased scan time, or scan failures are anticipated symptoms.

Possible Causes:

Accumulation of dust and particulate matter on the scan window.
Fingerprints or smudges from handling.
Residue from cleaning agents not designed for optical surfaces.
Scratches or abrasions on the scan window surface.
Environmental contaminants (e.g., airborne grease, cleaning solutions).
Electrostatic discharge (ESD) attracting dust particles.

Solution:

1

Safe Handling: Disconnect the Honeywell Xenon 1900 scanner from its power source and the host device.
2

Initial inspection: Visually inspect the scan window for visible contaminants.
3

Compressed Air: Use a can of compressed air to gently blow away loose dust and debris from the scan window. Hold the can upright and maintain a safe distance to avoid condensation.
4

Lens Cleaning Solution: Apply a small amount of lens cleaning solution (designed for optical surfaces) to a clean, lint-free microfiber cloth. Isopropyl alcohol (99%) can be used if no lens cleaning solution is available, but use sparingly.
5

Gentle Cleaning: Gently wipe the scan window in a circular motion with the dampened microfiber cloth. Avoid applying excessive pressure.
6

Drying: Use a separate, clean, dry, lint-free microfiber cloth to dry the scan window.
7

Re-inspection: Re-inspect the scan window for any remaining residue. Repeat steps 4-6 if necessary. Reconnect scanner to the host and test.

Safety Warning:

Safe Handling: Disconnect the scanner from power before cleaning. Avoid spraying cleaning solutions directly onto the scanner. Use only lens cleaning solutions or isopropyl alcohol. Ensure the scan window is completely dry before reconnecting the scanner. Static discharge (ESD) is possible in dry environments. Ground yourself before handling the scanner. DO NOT open the scanner casing. This voids the warranty and may trigger anti-tamper mechanisms.

Prevention:

Regularly clean the scan window (daily in high-traffic environments, weekly otherwise). Implement a policy to prevent touching the scan window with bare hands. Educate staff on proper cleaning procedures. Consider a scanner stand or holster to reduce handling.

Expert Tip:

For stubborn smudges, breathe lightly onto the scan window to create condensation before wiping with the microfiber cloth. This can help loosen the residue. Verify the cable connection is secure to prevent intermittent scan failures before assuming the window is dirty.

Frequently Asked Questions

•What type of cleaning solution is recommended for the Xenon 1900 scan window?

Use lens cleaning solution specifically designed for optical surfaces. Isopropyl alcohol (99%) can be used sparingly if lens cleaning solution is unavailable.

•How often should the Xenon 1900 scan window be cleaned?

Clean daily in high-traffic environments, or weekly otherwise.

•What should I do if the scan window has scratches?

Minor scratches may not significantly impact performance. However, deep scratches can degrade performance. Consider replacing the scanner if performance is unacceptable. Opening the scanner is not recommended.
