The Brother MFC J3720 Printer driver enables Windows to communicate with your printer and send print jobs with the correct settings. For network use, it helps your computer access the device over a shared local connection and provides printer-specific options that a basic Windows driver may not offer.

Key Features

• Network printing support: Use the Brother MFC J3720 Printer from a Windows computer connected to the same local network, once the printer’s network connection is configured.
• Printer-specific settings: Adjust available options such as paper size, media type, print quality, and page layout to suit everyday documents or larger print jobs.
• Windows compatibility: Choose the appropriate driver package for Windows 11, 10, 8, or 7, checking the download’s listed compatibility and system architecture before installation.
• Multifunction software options: Depending on the package, additional Brother utilities may provide scanning features and device management. A print-only driver does not necessarily include these tools.

How to Install

1. Check your Windows version. Open your computer’s system information to confirm the Windows edition and whether it uses a 32-bit or 64-bit system. Select a Brother MFC J3720 Printer driver package that explicitly supports your configuration.

1. Prepare the printer and network. Turn on the printer, load paper, and check that it is connected to your local network. Your computer must be able to reach that network; a guest connection or network isolation can prevent detection.

1. Download and open the installer. Save the compatible driver package, extract it if necessary, and run the setup program. Approve the Windows permission prompt if requested.

1. Select the connection method. Choose the network installation option and follow the prompts to locate your Brother printer. If automatic detection fails, use the printer’s IP address when the installer offers manual selection.

1. Complete setup and test printing. Finish the installation, restart Windows if prompted, and print a test page from the printer’s properties. If you also need scanning, confirm that the selected package includes the required scanner software and test that function separately.

Common Issues and Fixes

• Install fails or stalls: Uninstall any existing Brother MFC-J3720 driver, reboot, then run the full Brother driver package as administrator. Temporarily disable antivirus during installation and reconnect the printer only when prompted.
• Printer not detected: For USB, try another port/cable and avoid hubs. For wireless, confirm the MFC-J3720 and PC are on the same network, check the printer’s IP address, and re-run Brother’s wireless setup if needed.
• Driver/version conflicts: Remove old or Windows generic Brother entries in Programs and Features and Device Manager, restart the print spooler, then install the latest MFC-J3720 full driver package and reboot before printing or scanning.
