What causes fault code ASRS-007 (AS/RS Barcode Read Failure)?

Barcode label damaged, wrinkled, or missing. Scanner lens dirty — reduced read distance or reliability. Label orientation wrong — barcode not facing scanner. Scanner out of focus — focal distance changed due to mounting vibration. Ambient light interference — direct sunlight or reflection

How do I fix fault code ASRS-007?

Inspect barcode label — replace if damaged, missing, or wrinkled. Clean scanner lens with soft cloth. Verify label is positioned to face scanner at correct angle. Check scanner mounting — tighten if loose, verify focal distance. Test with known-good barcode in same position. If ambient light issue, install a light shield or switch to laser scanner

Hold a test barcode (printed fresh, known good) in front of the scanner. If it reads the test but not the pallet label, it's the label quality, not the scanner.
