The Brother MFC J870DW driver helps Windows communicate with your all-in-one printer over a network, enabling print jobs to reach the device and making supported settings available on your PC. Choose a Brother driver package that matches your version of Windows 11, 10, 8, or 7, and check whether it includes scanning software or only printer support.

Key Features

• Network printing: Connects Windows to the Brother MFC J870DW through your local network, so you can print without a direct USB connection.
• Print settings access: Provides controls for supported options such as paper size, media type, print quality, and two-sided printing.
• Scanning support with compatible software: A package containing the appropriate scanner driver lets supported Windows applications communicate with the device’s scanning functions.
• Device status information: Compatible Brother utilities can help you check printer availability and identify conditions that may interrupt a job.

How to Install

1. Confirm your Windows version. Check whether your PC runs Windows 11, 10, 8, or 7, and verify its system type where applicable. Select a package explicitly listed for your operating system; availability and included features may vary.

1. Prepare the network connection. Turn on the Brother MFC J870DW and connect it to your router using a supported wired or wireless connection. Make sure your computer is on the same local network. Guest networks may prevent devices from finding each other.

1. Download and start the installer. Save the compatible driver package, open it, and approve the Windows permission prompt if requested. If the download is compressed, extract its contents before running setup.

1. Select network installation. Follow the installer’s instructions and choose the network connection option when offered. Select your printer from the discovered devices. If it is missing, check its network connection and use its IP address if the installer supports manual discovery.

1. Verify printing and scanning. Finish setup, restart the computer if prompted, and print a test page from Windows printer settings. If you installed scanner support, test a scan as well. Successful printing alone does not confirm that the scanning components are configured.

Common Issues and Fixes

• Install fails or stalls: Disconnect the MFC-J870DW USB cable, remove old Brother software, reboot, then run the installer as administrator. Reconnect USB only when prompted; for Wi‑Fi, use Brother’s wireless setup on a 2.4 GHz network.
• Device not detected: Confirm the printer is on and connected. For USB, try another port directly on the PC, not a hub. For Wi‑Fi, verify the IP address and add the MFC-J870DW as a TCP/IP printer; restart the print spooler.
• Version conflicts or scan/print errors: Remove previous MFC-J870DW entries in Devices and Printers, install the full Brother driver package matching your Windows version and architecture, then reboot. Avoid mixing Windows Store and Brother drivers.
