| Issue | Solution | |-------|----------| | Illumination LED stays on constantly | Use the configuration barcode from the manual to set LED timeout to 3 seconds instead of Always On. | | Scan rate exceeds 300 scans/minute for hours | Reduce scan frequency or add cooldown periods. The scanner is rated for intermittent use, not continuous 24/7. | | Driver CPU usage high (Task Manager > Details) | Uninstall and reinstall the driver. A stuck interrupt request (IRQ) can cause 15-20% CPU usage, generating heat via USB polling. | | Firmware mismatch | Download the latest firmware from 4Barcode and flash the scanner via the "Firmware Upgrade Tool" (included with the driver package). |
