Lexmark T640 Driver

The Lexmark T640 driver enables Windows to communicate with your printer, turning documents into print jobs and making supported printing options available to your applications. For a network-connected T640, the correct driver helps your computer send jobs to the printer’s network address and use its installed features.

Key Features

• Network printing support: Connects Windows applications to a Lexmark T640 configured on your local network.
• Document controls: Provides access to supported settings such as paper size, orientation, copy count, and print quality.
• Paper-handling options: Lets you configure available trays and duplex printing when the corresponding hardware is installed.
• Shared printing setup: Supports configuring the printer for use from a Windows computer or through a shared print queue, depending on your network arrangement.

How to Install

1. Check your Windows version and system type. Before downloading, confirm whether you use Windows 11, 10, 8, or 7 and whether your system requires a 32-bit or 64-bit package. Verify that the selected driver explicitly supports your operating system and the Lexmark T640.

1. Prepare the printer connection. Turn on the printer and confirm that its network connection is active. Locate its IP address through the printer’s network settings or a printed network setup page. Your computer must be able to reach that address.

1. Download and open the driver package. Extract the files if necessary, then run the installer. Allow administrator access when prompted. If the package contains driver files without an installer, use Windows’ Add Printer option instead.

1. Add the Lexmark T640. Choose the network installation option and select the detected printer. If it does not appear, add it manually using its IP address. When Windows requests a driver, browse to the extracted files and select the appropriate model.

1. Confirm settings and test printing. Open Printer Properties, check that installed trays and any duplex unit are configured correctly, and print a test page. If the job remains queued, verify the printer’s IP address and port settings before reinstalling.

Driver availability and installation methods may vary across Windows versions. If an older package does not list your system, check whether Lexmark offers a compatible universal print driver that explicitly includes the T640 rather than assuming every package will work.
