MX850 series Driver

The Canon MX850 series driver connects your PIXMA MX850 multifunction printer to Windows so compatible software can access its printing and scanning functions. If you are setting up the device, reconnecting it after a Windows reinstall, or troubleshooting a detection problem, installing the correct driver is an important first step. Although sometimes listed under camera devices, the MX850 is a multifunction printer, so choose a printer or scanner package rather than a camera driver.

Key Features

• Printing support: Lets Windows send print jobs to the MX850 and access available settings such as paper size, print quality, and layout.
• Scanning access: A compatible scanner driver allows supported applications to communicate with the device’s scanner.
• Device configuration: Provides access to settings and maintenance options included with the selected Canon driver package.
• Legacy Windows compatibility: Driver options cover Windows 10, 8.1, 7, Vista, and XP, depending on the package and system architecture.

How to Install MX850 series Driver

1. Check your Windows version. Confirm your operating system and whether it is 32-bit or 64-bit. For Windows 10/11 users, note that Windows 11 is not listed among the supported systems here; do not assume a Windows 10 package will work.
2. Choose the matching package. Before starting your MX850 series driver download for Windows, check the model, OS compatibility, and whether you need printing support, scanning support, or both. Select the latest version available for your specific system.
3. Download safely. Use a trusted source, preferably Canon’s official support resources. A free download should not require purchasing a separate driver-update utility.
4. Run the installer. Open the downloaded file, approve any Windows permission prompt, and follow the instructions. Connect the device when requested.
5. Test the setup. Restart Windows if prompted, then print a test page and check scanning if you installed scanner support.

Keep your driver updated by checking for a compatible release when troubleshooting or changing Windows versions. Before you install an update, review its supported systems and instructions; a newer package is only useful if it matches your MX850 and your Windows configuration.

Common Issues and Fixes

• Install fails or stalls at “connecting printer.” Disconnect the USB cable until the Canon installer prompts for it, run setup as administrator, and remove old Canon MX850/PIXMA entries in Devices and Printers first. Avoid USB hubs.
• Printer not detected (USB or Wi-Fi). Use a direct USB port and different cable; for wireless, confirm the MX850 and PC are on the same 2.4 GHz network and re-detect with Canon IJ Network Tool. Install the scanner driver if printing works but scanning does not.
• Version conflicts after a Windows upgrade. Windows may install a generic PIXMA driver, breaking scan/fax. Uninstall the existing MX850 driver and Canon IJ Network Tool, reboot, then install the latest full MX850 series package and set it as default.
