The Brother MFC L3770CDW driver lets Windows communicate with your color multifunction printer, enabling print jobs and access to supported device settings. For a network setup, choose a Brother driver package that matches your Windows version and includes any additional scanning tools you need.

Key Features

• Network printing support: Connect to the printer over your local Ethernet or Wi-Fi network so connected computers can send documents without a direct USB connection.
• Print configuration: Access supported options such as automatic two-sided printing, paper size, tray selection, and color or monochrome output.
• Scanning integration: A compatible scanner driver or full software package can enable scanning to your computer; a print-only driver may not include this functionality.
• Windows compatibility: Select the appropriate download for Windows 11, 10, 8, or 7, checking the package’s supported editions and system architecture before installation.

How to Install

1. Check your Windows version.

Open your computer’s system information and confirm the Windows edition and whether it uses a 32-bit or 64-bit system. Select a package that explicitly supports your configuration.

1. Prepare the network connection.

Turn on the Brother MFC L3770CDW and connect it to your router using Ethernet or configure its wireless connection from the printer’s control panel. Make sure your PC can reach the same local network.

1. Download the appropriate driver.

Choose the printer driver for basic printing, or a full driver and software package if available for your operating system and you also need scanning tools. Verify the model name before downloading.

1. Run the installer.

Open the downloaded file, approve the Windows permission prompt if requested, and follow the setup instructions. Select the network connection option and choose your printer from the detected devices. If it is not listed, use its IP address when the installer offers that option.

1. Verify operation.

Complete setup and restart Windows if prompted. Print a test page, then check duplex and color settings in Printing Preferences. If you installed scanning components, try a scan to confirm that both functions work over the network.

Common Issues and Fixes

• Install fails or stalls: Disconnect USB, remove any partial Brother MFC-L3770CDW entries from Printers & scanners, reboot, then run the full driver package as administrator. Temporarily disable antivirus if it blocks the installer.
• Printer not detected (USB or network): For USB, use a direct rear-port connection and a known data cable. For network, confirm the printer and PC are on the same subnet, print a network configuration report, and add the printer by IP instead of hostname.
• Version/port conflicts: Remove older Brother drivers and stale TCP/IP or WSD ports before installing. Use the MFC-L3770CDW full package; don’t mix the Microsoft IPP class driver with Brother scan drivers. Update firmware if print/scan jobs fail after an upgrade.
