The Brother MFC 9870 driver helps Windows communicate with your printer, turning documents into print jobs the device can process. Installing the appropriate Brother driver also gives you access to printing preferences, making it easier to adjust output for everyday office tasks.

Key Features

• Printer communication: Provides the software connection Windows needs to send print jobs to the Brother MFC 9870.
• Print settings: Offers access to options such as paper size, orientation, and copy count, depending on the driver package.
• Application integration: Allows programs with a print function to use the printer through the Windows printing system.
• Queue management: Works with Windows print controls so you can view pending jobs, pause printing, or cancel documents when necessary.

How to Install

1. Check your Windows version. Confirm whether your computer runs Windows 11, 10, 8, or 7, and check its system type. Before downloading, verify that the package explicitly supports both your operating system and the Brother MFC 9870; older printer drivers may not work on newer Windows versions.

1. Download the appropriate package. Choose a printer driver that matches your system. Save it to an easy-to-find folder, and extract the files first if they arrive in a compressed archive.

1. Prepare the printer. Turn on the device and check that it has paper and no active error messages. Follow the driver package’s instructions for when to connect the printer to your computer.

1. Install the driver. Run the setup program and follow its prompts. If the download contains driver files without an installer, use the Windows Add Printer wizard and select the extracted driver location when requested.

1. Test the connection. Open the printer’s properties in Windows and print a test page. If printing fails, check the cable, selected printer port, and print queue before reinstalling.

For this older Brother model, compatibility matters more than choosing the newest available download. Printing support does not automatically include scanning or other multifunction features; those may require separate software with its own Windows compatibility requirements.

Common Issues and Fixes

• Install fails or stalls: Run the Brother MFC 9870 full driver package as administrator, disconnect USB until prompted, and temporarily disable antivirus. Remove previous Brother printer/scanner entries in Print Management before retrying; don’t rely on Windows Update’s generic driver for scan/fax features.
• Device not detected: Check the MFC 9870’s USB/parallel cable and port, power-cycle the printer, and try another port/cable. For USB, connect directly, not through a hub. Confirm the correct MFC 9870 port is selected in Printer Properties.
• Driver/version conflicts: Uninstall old Brother MFC 9870 print, scan, and fax drivers, restart, then install only one full package matching your Windows version. Avoid mixing Windows Update and Brother packages; if needed, use compatibility mode for older Windows drivers.
