The Canon DR-C240 Scanner driver connects your document scanner to Windows and allows compatible applications to access its scanning functions. Installing the correct Canon driver helps your computer recognize the device and gives you control over settings for everyday document capture.

Key Features

• Scanning application access: Enables compatible software to communicate with the Canon DR-C240 through supported scanning interfaces, such as TWAIN or ISIS, depending on the driver package.
• Adjustable capture settings: Provides access to options such as resolution, color mode, and paper size so you can tailor scans to text documents, forms, or mixed paperwork.
• Two-sided document scanning: Supports the scanner’s duplex capabilities in compatible applications, helping you capture both sides of a page without manually turning it over.
• Windows integration: Establishes the connection needed to use the scanner on a supported Windows system. Choose a package specifically listed for your version of Windows 11, 10, 8, or 7 and its system architecture.

How to Install

1. Check your Windows version. Open your system information and confirm which Windows edition you use, along with whether it is 32-bit or 64-bit. Driver availability can vary between operating systems.

1. Select the matching Canon package. Download a driver that explicitly lists the DR-C240 and your Windows version. Review any included installation notes, especially if you are replacing an older driver.

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

1. Run the installer. Extract the downloaded files if necessary, launch the setup program, and follow the prompts. Approve administrator access when requested, then connect and power on the scanner at the appropriate stage.

1. Verify scanning works. Restart Windows if prompted, open a compatible scanning application, and select the Canon DR-C240 as the source. Scan a test page and check the paper size, orientation, and image quality.

If the scanner does not appear in your application, confirm that it is powered on and connected securely. Try a direct USB connection rather than a hub, and make sure the application is using the correct scanner source.

Common Issues and Fixes

• Install fails or rolls back: Run the Canon DR-C240 installer as administrator, close scanner apps, and temporarily disable antivirus. Confirm the driver matches your Windows version and 32/64-bit architecture, then reboot and retry.
• Scanner not detected: Connect the DR-C240 directly to a USB port, not a hub. Check Device Manager for unknown/imaging devices, try another USB cable/port, power-cycle the scanner, and ensure the Windows Image Acquisition (WIA) service is running.
• Version conflicts or old driver persists: Uninstall existing Canon scanner drivers/utilities in Programs and Features, disconnect the scanner, reboot, then install the latest DR-C240 driver. Remove leftover imaging devices in Device Manager before reconnecting.
