The Canon i SENSYS MF645Cx driver connects this colour multifunction printer to your Windows computer, allowing applications to send print jobs with the correct settings. Installing a compatible Canon driver helps you access the printer’s capabilities rather than relying on basic Windows printing options. Choose a download that explicitly supports your version of Windows 11, 10, 8, or 7.

Key Features

• Printer-specific settings: Adjust paper size, orientation, colour output, and print quality through the Canon driver interface.
• Two-sided printing controls: Select automatic duplex printing for supported paper types to reduce paper use when printing longer documents.
• USB and network connectivity: Configure printing over a direct USB connection or a supported network connection, depending on your office setup.
• Scanning support with the appropriate software: Compatible Canon scanner drivers and utilities allow the MF645Cx to send scanned documents to your PC. These may require a separate download from the print driver.

How to Install

1. Check your Windows version. Open your computer’s system information and confirm both the Windows edition and whether it uses a 32-bit or 64-bit system. Match these details to the driver’s listed compatibility; not every package supports every Windows version.

1. Download the required Canon package. Select the printer driver for the Canon i SENSYS MF645Cx. If you also need scanning, check whether the download includes scanner support or whether a separate driver and utility are required.

1. Prepare the connection. Turn on the printer. For network installation, make sure the printer and computer are on the same accessible network. For USB installation, follow the installer’s instructions about when to connect the cable.

1. Run the installer. Extract the downloaded archive if necessary, then launch the setup program. Approve any Windows permission prompt, select your connection method, and choose the MF645Cx when it appears in the device list.

1. Verify the setup. Restart your computer if prompted, then print a test page from Windows printer settings. If you installed scanning software, try a sample scan as well. Check the selected printer, connection, and paper settings if the first test does not complete correctly.

Common Issues and Fixes

• Installation fails or stalls: Disconnect the printer, uninstall older Canon i-SENSYS/MF drivers and scanner software, run the installer as administrator, and restart the Print Spooler service.
• Device not detected: For USB, avoid hubs and use a direct port. For network, confirm the MF645Cx IP is on the same subnet, ping it, then create a standard TCP/IP port manually instead of relying on WSD.
• Driver/version conflicts: Remove old UFR II or Generic Plus queues and leftover ports in Print Management, reboot, then install the latest Canon MF645Cx driver before testing print and scan.
