The Brother MFC 990CW network driver helps Windows communicate with your multifunction printer over a local network. Installing the appropriate Brother software allows your computer to send print jobs and, when the matching scanner components are included, access scanning functions. Before downloading for Windows 11, 10, 8, or 7, check that the package explicitly supports your Windows version and system architecture.

Key Features

• Network printing support: Connects Windows applications to the Brother MFC 990CW through your existing wired or wireless network.
• Print preference controls: Provides access to supported settings such as paper size, media type, print quality, and color output.
• Scanning integration: Compatible scanner software can enable document and photo scanning from the network-connected device. Availability depends on the selected package and operating system.
• Device communication: Helps Windows identify the printer and route jobs to the correct network device. Status information may also be available through accompanying Brother utilities.

How to Install

1. Check your Windows configuration. Confirm whether you use Windows 11, 10, 8, or 7 and whether your system is 32-bit or 64-bit. Choose a package that lists your configuration; do not assume an older driver supports a newer Windows release.

1. Prepare the network connection. Turn on the Brother MFC 990CW and connect it to your router using its supported wired or wireless setup. Make sure your computer can reach the printer on the same local network.

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

1. Select the network installation option. Follow the on-screen instructions and choose the printer from the detected devices. If it is not found, verify its network connection and use its IP address if the installer offers manual discovery.

1. Confirm operation. Complete setup, restart Windows if prompted, and print a test page. If you installed scanner components, test a scan as well. For detection problems, check the printer’s network settings and any firewall permissions rather than disabling security software entirely.

Common Issues and Fixes

• Install fails or stalls: Run the Brother full driver package as administrator, temporarily disable antivirus/firewall during setup, and remove any previous MFC-990CW software first. Do not use a generic Windows driver if scanning/fax is needed.
• Device not detected: Power on the MFC-990CW and reconnect USB directly to the PC, not a hub. For wireless, confirm the printer is on the same 2.4 GHz network and use the Brother setup wizard or WPS; print a network configuration report to check its IP address.
• Version/driver conflicts: Uninstall old Brother MFC-990CW entries in Programs and Features and Device Manager, delete the printer in Devices and Printers, restart, then reinstall the correct 32/64-bit package.
