The Canon imageFORMULA DR M140 is a document scanner, and its driver allows Windows to communicate with the device for scanning tasks. Installing the appropriate Canon driver helps compatible scanning applications recognize the scanner and access settings for capturing documents.

Key Features

• Application connectivity: Connects the DR M140 to compatible document-capture software so you can start scans and manage available scanner settings from your computer.
• Adjustable scan settings: Provides access to options such as resolution, color mode, and document size, helping you balance readability with storage needs.
• Two-sided document capture: Enables compatible software to use the scanner’s duplex capabilities, making it easier to digitize documents printed on both sides.
• Windows integration: Supports communication between the scanner and your operating system when the correct driver package is installed. Check the package details for Windows 11, 10, 8, or 7 compatibility before downloading.

How to Install

1. Check your Windows version. Open your computer’s system information to confirm the Windows edition and whether it uses a 32-bit or 64-bit architecture. Select a Canon imageFORMULA DR M140 driver package that explicitly supports that configuration.

1. Prepare the scanner and computer. Close any scanning applications. Keep the scanner’s USB cable disconnected until the installer or Canon’s setup instructions tell you to connect it.

1. Download and open the driver package. Save the installer to an accessible folder. If the download is compressed, extract its contents before running the setup program. Approve the Windows permission prompt if it appears.

1. Follow the installation prompts. Complete the setup process, then connect the scanner directly to a USB port and turn it on when instructed. Restart Windows if the installer requests it.

1. Run a test scan. Open a compatible scanning application, select the DR M140 as the scanning source, and scan a sample page. If the scanner is not listed, check its power and USB connection, then confirm that the installed driver matches your Windows version.

The driver handles device communication, but a separate scanning application may be needed to capture and save documents. Review the download’s contents to see whether scanning software is included or must be installed separately.

Common Issues and Fixes

• Install fails or rolls back: Run the Canon DR-M140 installer as administrator, leave the USB cable disconnected until prompted, and remove any previous Canon scanner driver via Programs and Features and Devices and Printers. Reboot before retrying.
• Device not detected: Connect the DR-M140 directly to a rear USB 2.0 port, not a hub, and confirm it powers on. Check Device Manager for unknown devices and ensure the WIA (Windows Image Acquisition) service is running; then reinstall the driver.
• Version/TWAIN conflicts: Uninstall older DR-M140 drivers and Canon CaptureOnTouch before installing the current 64-bit package. Close other scanning apps, then select the correct Canon DR-M140 TWAIN source in your document-scanning software.
