The Canon imageRUNNER ADVANCE C256i III driver allows Windows to communicate with this multifunction printer over your office network. Installing a compatible driver helps applications send print jobs correctly and gives you access to the device’s supported printing options.

Key Features

• Network printing support: Connects your Windows computer to the printer through an existing network, allowing users to send documents without a direct USB connection.
• Print layout and output controls: Provides settings for paper size, orientation, copy count, and supported two-sided printing options.
• Color and quality settings: Lets you adjust available color and print-quality preferences to suit everyday documents, presentations, and other office materials.
• Device configuration options: Helps Windows recognize supported paper sources and installed accessories when the driver is configured to match the printer.

How to Install

1. Check your Windows version. Select a Canon imageRUNNER ADVANCE C256i III driver package that explicitly supports your system: Windows 11, 10, 8, or 7. Also confirm whether the package matches your Windows architecture, as availability can vary by driver release.

1. Prepare the network connection. Turn on the printer and ensure your computer can reach it over the network. If you need to add it manually, find the printer’s IP address using its control panel or network configuration information.

1. Download and extract the driver. Save the compatible package to your computer. If it is compressed, extract its contents before starting the installation.

1. Run the installer. Open the setup program and approve the Windows permission prompt if requested. Choose the network connection option, then select the detected printer or enter its IP address. If no installer is included, use Windows’ Add Printer option and browse to the extracted driver files when prompted.

1. Confirm settings and test printing. After installation, open the printer’s properties, check the available paper sources and output options, and print a test page. If the printer cannot be found, verify its IP address and network accessibility before reinstalling.

A print driver does not necessarily include scanning utilities or other multifunction software. If you also need scanning, check for a separate Canon package compatible with your device and Windows version.

Common Issues and Fixes

• Installer fails or rolls back: Disconnect VPN, run Canon setup as administrator, and remove any existing C256i III queue/driver in Print Management before retrying. Use the UFR II driver matching your Windows version.
• Device not detected on network: Give the copier a static IP or DHCP reservation, verify port 9100/SNMP reachability, then add a Standard TCP/IP port manually with the correct IP instead of relying on WSD discovery.
• Version conflicts or duplicate queues: Uninstall old Canon iR ADVANCE and generic Microsoft drivers, clear the print spooler, reboot, and install only one C256i III driver package. Avoid mixing UFR II and PCL drivers on the same port.
