The Canon CanoScan N670U is a flatbed scanner, and its driver allows Windows to communicate with the device so compatible applications can capture documents and photos. Before downloading, check the package’s supported operating systems: this is a legacy model, so compatibility with Windows 11, 10, 8, or 7 should not be assumed.

Key Features

• Scanner communication: A compatible driver enables your computer to recognize the CanoScan N670U over USB and send scanning commands.
• Scan settings: Depending on the driver and application, you can adjust resolution, color mode, and scan area to suit text documents or photographs.
• Application integration: A supported TWAIN driver lets compatible scanning and image-editing software access the scanner.
• Preview controls: Compatible software can provide a preview before the final scan, helping you crop unwanted edges and check document placement.

How to Install

1. Check your Windows version and architecture. Open your system information to confirm whether you use Windows 11, 10, 8, or 7 and whether the installation is 32-bit or 64-bit. A driver for an older 32-bit system will not necessarily work on a newer 64-bit PC.

1. Verify the download details. Choose a package that explicitly lists the Canon CanoScan N670U and your operating system. Although it may appear in a printer category, this device requires a scanner driver, not a printer driver. If your Windows version is not listed, do not assume the package supports it.

1. Prepare for setup. Close scanning applications and extract the downloaded archive if needed. Follow the package’s instructions about whether to disconnect the scanner before installation.

1. Install the compatible driver. Run the setup program and follow its prompts, connecting the USB cable when instructed. If the package requires manual installation, use Device Manager and select the extracted driver folder. Restart Windows if requested.

1. Test a scan. Open a compatible scanning application, select the CanoScan N670U, and preview a document. If the scanner is unavailable, check its USB connection and driver status in Device Manager.

If no compatible driver is available for your Windows installation, compatibility mode alone may not resolve the issue. Check Canon’s support information or a reputable third-party scanning application’s device support list before trying an alternative.

Common Issues and Fixes

• Install fails or setup stops: The N670U uses legacy Canon ScanGear/TWAIN drivers. Run the installer as administrator in Windows compatibility mode, and avoid using Device Manager’s “Update driver” for this scanner. On 64-bit Windows, confirm the package includes 64-bit TWAIN support.
• Scanner not detected: Connect the N670U directly to a rear USB port, not a hub. Try a known-good USB cable, check Device Manager for “Unknown Device,” then uninstall the scanner and rescan hardware before reinstalling.
• Driver/version conflicts: Remove old Canon ScanGear, Toolbox, and other scanner TWAIN/WIA entries first. Install only one N670U driver package, then select “Canon N670U” as the TWAIN source in your scanning app.
