The Canon Fax L140 driver enables Windows to communicate with this laser fax and printer, allowing you to send documents from your computer to the device’s print queue. Installing the appropriate Canon driver helps Windows recognize the printer and makes its available printing preferences accessible.

Key Features

• Windows printing support: Connects compatible applications to the Canon Fax L140 so you can print documents, forms, and correspondence.
• Print preference controls: Provides access to supported options such as paper size, orientation, and copy count through the printer’s settings.
• Print queue integration: Works with Windows print management tools, letting you view pending jobs and cancel documents when necessary.
• Device-specific communication: Supplies the instructions Windows needs to send print data to this model rather than relying solely on generic printer support.

How to Install

1. Check your Windows version. Before downloading, confirm whether your PC runs Windows 11, 10, 8, or 7, and check its system type. Choose a package explicitly compatible with both your operating system and the Canon Fax L140; older drivers may not support every listed Windows version.

1. Prepare the printer. Connect the device to power, load paper, and clear any errors shown on its display. If you are using a USB connection, leave the cable disconnected until the installer asks you to connect it, unless the package instructions say otherwise.

1. Download and open the driver package. Save the compatible Canon driver to your computer. Extract it first if it is compressed, then launch the setup program and approve the Windows permission prompt if one appears.

1. Complete the setup. Follow the on-screen instructions, select the appropriate connection when prompted, and connect the printer. If the download contains no setup program, use Windows’ Add printer option and browse to the extracted driver files.

1. Verify printing. Open the printer settings in Windows, select the Canon Fax L140, and print a test page. If the device does not appear, check the cable and connection, then restart the printer and computer before trying again.

This download is for computer printing support. Do not assume it adds scanning or PC-based faxing unless those functions are explicitly included in the driver package documentation.

Common Issues and Fixes

• Install fails or setup stops: Confirm the download matches your Windows version and 32/64-bit architecture. Run the Canon setup as administrator, disconnect the USB cable until prompted, and use Windows compatibility mode for older L140 packages.
• Fax not detected: Try another USB port/cable, power-cycle the Canon Fax L140, and check Device Manager for unknown/imaging devices. Reconnect only when setup asks; enable Windows Fax Service under Windows Features if PC faxing is needed.
• Driver/version conflicts: Uninstall older Canon fax drivers and remove stale L140 ports/queues in Print Management, then reboot before reinstalling the latest package. Set the L140 as the default fax printer to avoid conflicts with other fax devices.
