Risoluzione dei problemi
Problemi comuni e soluzioni:
- Lo scanner non si connette:
- Assicurarsi che lo scanner sia completamente carico.
- Verify the correct connection mode (wired, 2.4G dongle, or Bluetooth) is selected and properly set up.
- For Bluetooth, ensure your host device's Bluetooth is on and the scanner is discoverable.
- Provare a riavviare sia lo scanner sia il dispositivo host.
- Lo scanner non legge i codici a barre:
- Assicurarsi che il codice a barre non sia danneggiato o macchiato.
- Check that the scanning beam is properly aligned with the barcode.
- Verify the barcode type is supported by the scanner (1D, 2D, QR, etc.).
- Regolare la distanza tra lo scanner e il codice a barre.
- Clean the scan window if it is dirty.
- Data not transmitting correctly:
- Confirm the scanner is successfully paired/connected to the host device.
- Check the input field on your host device (e.g., a text editor, spreadsheet) is active and ready to receive input.
- Ensure no other applications are interfering with keyboard input.
- Breve durata della batteria:
- Assicurarsi che lo scanner sia completamente carico prima dell'uso.
- Reduce continuous scanning if not needed.
- Battery performance may degrade over time; consider battery replacement if issues persist after prolonged use.
Manutenzione
- Pulizia: Use a soft, dry cloth to clean the exterior of the scanner. For the scan window, use a lint-free cloth and a mild glass cleaner if necessary. Avoid abrasive materials or harsh chemicals.
- Magazzinaggio: Conservare lo scanner in un luogo fresco e asciutto, lontano dalla luce solare diretta e da temperature estreme.
- Cura della batteria: Per una durata ottimale della batteria, evitare di scaricarla completamente frequentemente. Se si prevede di non utilizzarla per lunghi periodi, caricare la batteria fino a circa il 50% e ricaricarla ogni pochi mesi.
