Canon LBP6780 3580 UFR II Driver

The Canon LBP6780 3580 UFR II driver enables Windows to communicate with your Canon printer and process documents using Canon’s UFR II printing system. Installing a compatible driver helps you access printer settings and avoid problems caused by a missing or incorrectly matched driver.

Key Features

• UFR II print processing: Provides the software interface needed to send print jobs from Windows applications to the printer using Canon’s UFR II technology.
• Document setup controls: Gives you access to settings such as paper size, orientation, copy count, and page layout, with additional options depending on the printer configuration.
• Print output preferences: Lets you adjust available quality and finishing settings to suit everyday documents and more detailed print jobs.
• Windows integration: Makes the printer available through standard Windows print dialogs. Choose a package that explicitly supports your version of Windows 11, 10, 8, or 7 and your system architecture.

How to Install

1. Check your Windows version. Open your system information to confirm the Windows edition and whether it uses a 32-bit or 64-bit architecture. Windows 11 requires a 64-bit driver package.
2. Select the matching download. Verify that the driver lists support for the Canon LBP6780 3580 UFR II and your operating system. Extract the downloaded files if they are provided in a compressed archive.
3. Prepare the printer connection. Turn on the printer. For a network installation, make sure the computer can reach it on the network. For USB installation, follow the installer’s instructions about when to connect the cable.
4. Run the installer. Open the setup program and allow administrator access if prompted. Follow the on-screen instructions, choose the appropriate connection method, and select the correct printer when it appears.
5. Confirm successful setup. Open the Windows printer settings and print a test page. Review the paper size and any installed printer options before starting regular print jobs.

If setup cannot detect the printer, check the USB connection or network address before trying again. When replacing an existing driver, remove an outdated printer entry only after confirming that it is no longer needed.

Common Issues and Fixes

• Installation fails or stops midway: Remove any existing Canon LBP/UFR II printer queues and drivers via Print Management, reboot, then run the LBP6780/3580 UFR II installer as administrator. Match the Windows architecture (32/64-bit) and pause antivirus if setup is blocked.
• Device not detected: Confirm the printer is on and connected directly to a rear USB port, not a hub. For network use, verify the IP address is on the same subnet, then create a Standard TCP/IP port manually and select the Canon UFR II driver.
• Driver version conflicts: Old UFR II or generic Canon drivers can create duplicate queues or “driver unavailable” errors. Uninstall all Canon LBP driver packages, reboot, install the latest UFR II package, and remove leftover duplicate printer entries.
