Diagnostic report on Datalogic Gryphon laser scanner interference from X-ray machines. Includes causes, solutions, prevention, and safety protocols.
Minimum of 3 meters, increasing if interference persists.
Look for visible cuts, fraying, or exposed wires. Check if the cable is a shielded type (usually thicker with a metallic braid inside).
No, only use a soft, dry, lint-free cloth. Avoid any liquids.
Laser scanners operate using focused light beams reflected from barcodes. X-ray machines emit electromagnetic radiation. While barcode scanners are not designed to operate in X-ray fields, high-intensity radiation could potentially affect the scanner's internal photodiode sensitivity or induce transient electromagnetic interference (EMI) within the scanner's circuitry, thereby disrupting signal processing. Specific vulnerabilities will depend on the scanner's shielding and circuit design. Baud rate is irrelevant to this issue. Primary concern is EMI induced by the X-ray emissions.
Laser scanner exhibiting intermittent or complete failure to decode barcodes. Occurrence correlates with proximity to active X-ray equipment. Observed as laser beam distortion or complete absence. Possible data transmission errors post-scan attempts.
The Datalogic Gryphon contains a laser. Avoid direct eye exposure to the laser beam. Safe Handling: Disconnect the scanner from the power source before performing any cleaning or maintenance. Do not use excessive force when connecting or disconnecting cables to avoid damage. Do not submerge the scanner in water or cleaning fluids. Avoid using the scanner in areas with excessive moisture or dust.
Try using a ferrite choke on the scanner cable near the connection point to the host system to further reduce EMI. Specifically, attach the ferrite choke as close to the host terminal as possible.
