Honeywell Xenon 1900: Scan Angle Adjustment... | terminalfaults.org

Technical Background:

The Xenon 1900 adjusts its scan angle electronically via internal lens adjustments controlled by firmware. Software commands sent from the host system (e.g., cash register) or configuration barcodes control these adjustments. Possible causes include: corrupted configuration settings, communication errors between the host and the scanner, or physical obstruction of the scan window. Ambient light interference can also impact scan performance.

Symptoms:

Reported inability to adjust the scan angle of the Honeywell Xenon 1900 barcode scanner. This manifests as difficulty in scanning barcodes from certain positions or distances.

Possible Causes:

Incorrect scanner configuration settings preventing scan angle adjustment.
Damaged or loose USB or serial cable causing communication failure.
Electrostatic discharge (ESD) affecting the scanner's internal electronics.
Lens obstruction (smudges, debris) affecting scan pattern projection.
Firmware corruption causing malfunction of internal adjustment mechanisms.
Host system not sending the correct commands to initiate scan angle adjustment.

Solution:

1

Verify the scanner is properly connected to the host system with a functioning cable. Test with a known-good cable.
2

Clean the scanner window with a microfiber cloth and approved lens cleaner. Avoid abrasive materials.
3

Scan the factory default configuration barcode to reset the scanner to its original settings. This will clear any custom configurations that might be causing the issue. (Refer to the Honeywell Xenon 1900 User Guide for this barcode).
4

Check the host system's software or configuration utility to ensure that scan angle adjustments are enabled and correctly configured.
5

If using a serial connection, verify the baud rate, parity, and other communication settings are correctly configured on both the scanner and the host system.
6

Power cycle the scanner by disconnecting and reconnecting the cable. This can resolve temporary communication glitches.
7

Check Honeywell's website for the latest firmware for the Xenon 1900. If a newer version is available, update the scanner's firmware according to the manufacturer's instructions.

Safety Warning:

Safe Handling: When disconnecting the scanner, ensure the host system is powered down or in a safe state. Avoid pulling the cable directly; disconnect by grasping the connector. Be aware of ESD risks, especially in dry environments. Avoid spraying liquids directly onto the scanner; apply cleaner to a cloth first.

Prevention:

Regularly clean the scanner window to prevent obstructions. Implement cable strain relief to avoid damage to the connector. In dry environments, use anti-static mats to minimize the risk of ESD. Periodically verify the scanner's configuration settings to ensure they are correct.

Expert Tip:

Some Xenon 1900 models may have a 'presentation mode' that interferes with manual scan angle adjustments. Try toggling presentation mode on or off (consult the user manual for the specific barcode or setting). Also, a poor USB connection can cause erratic behaviour, use a high-quality USB cable and avoid long cable runs without a powered hub.

Frequently Asked Questions

•What is the part number for the recommended replacement cable?

Refer to the Honeywell Xenon 1900 User Guide for compatible cable part numbers. Ensure the cable is shielded to minimize interference.

•Where can I download the latest firmware for the Xenon 1900?

Firmware updates are available on the Honeywell website under the 'Downloads' section for the Xenon 1900 model. Requires a Honeywell account.

•What type of cleaning solution is recommended for the scanner window?

Use a non-abrasive lens cleaner specifically designed for optical surfaces. Isopropyl alcohol (90% or higher) can also be used sparingly. Always apply the cleaner to a cloth, not directly to the scanner window.
