The scanner features four convenient one-touch buttons for quick operations:
- Spausdinimo mygtukas: Scans and sends the image directly to your printer.

The Auto-Scan function allows the scanner to automatically initiate a scan when the lid is closed, enhancing efficiency for continuous scanning tasks.

Trikčių šalinimas
This section addresses common issues you might encounter with your VIISAN 3120 scanner.
- White Lines on Scans: This is typically caused by dust or debris on the scanner glass or the calibration strip. Refer to the "Cleaning the Scanner Glass" section for instructions. If the issue persists after cleaning, please contact customer support.
- Unclear or Blurred Scans: Ensure the document is placed flat on the scanner glass. As the scanner uses a CIS sensor, it is not suitable for scanning three-dimensional objects.
- Scanner Not Detected / Software Issues:
- Verify that the USB cable is securely connected to both the scanner and the computer.
- Ensure the power adapter is properly connected and the scanner is powered on.
- Confirm that the correct drivers and ViiScan software are installed. Reinstalling the software may resolve persistent issues.
- For macOS users, ensure you are using the ICA driver and that your macOS version is 10.15 or later.
- Lėtas nuskaitymo greitis: Scanning at higher DPI settings (e.g., 1200 dpi) will naturally take longer. Reduce the resolution if speed is a priority.
