Epson NX400/SX400/TX400/PX-501A Driver

The Epson NX400/SX400/TX400/PX-501A driver helps Windows recognize and communicate with the corresponding Epson multifunction device. If you are setting up one of these models, reinstalling Windows, or troubleshooting a detection problem, you need a driver that matches both your device and operating system. Although listed under Camera, these model names refer to Epson multifunction printers, so check whether the package provides printing, scanning, or another imaging component before downloading.

Key Features

• Device communication: Allows Windows and compatible applications to access the functions covered by the installed driver.
• Function-specific support: Depending on the package, provides printer settings or scanning access; separate printer and scanner software may be required.
• Windows compatibility: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP. Individual packages may support only some of these systems.
• Setup and troubleshooting: Installing the correct package can help address missing-device messages or communication problems caused by an absent or mismatched driver.

How to Install Epson NX400/SX400/TX400/PX-501A Driver

1. Confirm your model and Windows edition. Check the label on your Epson device and determine whether your Windows installation is 32-bit or 64-bit.
2. Choose the appropriate package. Before starting your Epson NX400/SX400/TX400/PX-501A driver download for Windows, verify the supported models, operating systems, and included functions. For Windows 10/11 users, note that Windows 11 is not included in the listed support; do not assume a Windows 10 package is compatible.
3. Download from a trusted source. Prefer Epson’s official support resources for a free download, and select the latest version available for your specific model and Windows edition.
4. Run the installer. Extract the downloaded archive if necessary, launch the setup program, and follow its prompts. If using USB, connect the device when instructed rather than assuming it must be connected beforehand.
5. Check operation. Restart Windows if requested, then try a test print or scan, depending on the component you installed. If detection fails, check the cable, connection, and selected device.

Keep your driver updated when a compatible release addresses an issue you encounter or supports a system change. Before you install an update, review its compatibility notes—especially on older Windows versions—and retain a working installer in case you need to restore your setup.

Common Issues and Fixes

• Install fails or stops midway: Disconnect the USB cable until the installer asks, run the Epson setup as administrator, and temporarily disable antivirus/firewall blocking. Use the exact NX400/SX400/TX400/PX-501A driver—not a generic Epson or Windows inbox driver.
• Device not detected: Power on the printer, connect directly to a rear USB port (avoid hubs), try another cable, and restart the Print Spooler service. Reconnect USB only when prompted.
• Version conflicts or missing scanning: Uninstall old Epson printer and scanner software, reboot, then install the current package for your Windows version. Remove duplicate printer queues in Devices and Printers before reinstalling.
