The Epson WF 3620 3640 Series driver helps Windows communicate with your Epson multifunction printer over a network, allowing print jobs and supported settings to pass between the computer and device. Choose a package that matches your printer model and Windows version to help avoid detection issues or unavailable printing options.

Key Features

• Network printing support: Enables communication with a compatible Epson printer connected to your local network by Wi-Fi or Ethernet.
• Printing preferences: Provides access to supported options such as paper size, orientation, print quality, and two-sided printing.
• Device status information: Compatible Epson utilities may display printer availability, ink information, and alerts that help you identify common printing problems.
• Windows-specific setup: Selecting the appropriate driver for Windows 11, 10, 8, or 7 helps ensure the software works with your operating system and system architecture.

How to Install

1. Check your model and Windows version. Confirm whether you have a WF-3620 or WF-3640, then check your Windows edition and whether it uses a 32-bit or 64-bit system. Verify that the selected download supports that combination.
2. Prepare the network connection. Turn on the printer and connect it to your router through Wi-Fi or Ethernet. Make sure your computer can reach the same local network; guest networks may prevent device discovery.
3. Download and run the installer. Save the matching Epson WF 3620 3640 Series driver package, extract it if necessary, and launch the setup program. Approve the Windows permission prompt if requested.
4. Select your network printer. Follow the installation prompts and choose the network connection option when offered. If the printer does not appear, check its network connection and use its IP address if the installer provides that option.
5. Confirm successful installation. Finish setup, restart Windows if prompted, and print a test page from the printer settings. Review the paper and duplex preferences before starting regular print jobs.

Scanning may require a separate Epson scanner driver or utility. If printing works but scanning is unavailable, check the software requirements for your exact model rather than reinstalling the network printing driver alone.

Common Issues and Fixes

• Install fails or stalls: Disconnect the WF-3620/3640 USB cable, remove any existing Epson printer entries in Devices and Printers, then run the Epson installer as administrator before reconnecting.
• Printer not detected: For USB, use a direct rear port instead of a hub and power-cycle the printer. For wireless, confirm the printer and PC are on the same network and rerun Epson’s network setup.
• Driver/version conflicts: Delete duplicate WF-3620/3640 queues and avoid mixing Windows WSD/class drivers with the full Epson package. Install the matching Epson driver for your Windows version, then set the correct queue as default.
