Resolving Issues with the Epson Workforce ES 400 II Not Functioning

If your Epson Workforce ES-400 II Duplex Document Scanner is experiencing issues, several factors could contribute to its malfunction. These might include power-related problems such as damaged cables, loose connections, or electrical surges, as well as outdated drivers, software glitches, or incorrect configuration settings. Additionally, issues like paper jams, blockages, or unclean rollers may also hinder its performance.

How can I get my Epson Workforce ES-400 II operational?

1. Verify connections

Initially, if your scanner is connected via Wi-Fi, confirm that it is linked to the same network as your computer. Also, inspect the power cord for any faults—unplugging and re-plugging it can ensure a secure connection. Furthermore, ensure the USB cable linking the scanner to your computer is properly attached and in good condition.

2. Inspect for paper jams or obstructions

A paper jam or other obstructions can disrupt the normal functionality of the scanner. To resolve blockages, follow these instructions:

1. Power off the scanner and disconnect it from the power source.
2. Open the scanner lid to access the paper feed area and examine the paper tray, paper path, and any other accessible regions for any jams.
3. If you detect paper, debris, or dust, carefully pull the paper out in the direction of the feed path. If there’s a stubborn jam, gently extract the paper from both ends without tearing.
4. While accessing the feed area, clean the paper feed rollers using a mild soap solution and allow them to air dry for a few minutes.
5. After cleaning, close the lid and power on the scanner to check if the problem has been resolved.

3. Check the scanner’s settings

1. Open the Epson Scan application or any similar scanning software to begin scanning your documents.
2. Look for the “Select Scanner”option on the software’s homepage to ensure that Epson WorkForce ES-400 II is chosen. This step is particularly crucial if you have multiple scanners linked to your computer.
3. Next, verify that the scan mode (color, black and white, auto-detect) and the resolution settings (300 dpi, 600 dpi) correspond to your intended configuration.
4. Also, check if the selected paper size and type in the settings align with the document you are scanning.

4. Set the scanner as the default device

1. Press Windows + I to open the Settings application.
2. Navigate to Bluetooth & devices, then select Printers & scanners.
   

   

3. Under Printers & Scanners, locate Epson WorkForce ES-400 II and select it. If it’s not visible, ensure the scanner is properly connected and powered on.
   

   

4. On the next page, next to Epson WorkForce ES-400 II, click the Set as default option.
   

   

5. If you cannot find it, return to the previous settings page, toggle off the option “Let Windows manage my default printer”, and then try to set the scanner as the default device manually.
   

   

5. Update the device drivers

1. Press Windows + R to access the Run dialog.
   

   

2. Input devmgmt.msc and press OK to launch the Device Manager.
3. Expand the Imaging Devices section. Right-click on the Epson WorkForce ES-400 II scanner and select Update Driver from the menu.
   

   

4. Click on “Search automatically for drivers.”If Windows is unsuccessful in locating a driver, you can visit the Epson Support website for assistance.
   

   

5. Type Epson WorkForce ES-400 II into the search bar and click Search.
   

   

6. Select your operating system and then click Go.
   

   

7. Find the scanner driver in the list and expand it. Click the Download button to begin the download.
   

   

8. Once downloaded, double-click the file, and follow the on-screen prompts to complete the installation.

If you’ve tried all these steps and the scanner still isn’t working, it might indicate a hardware issue or worn components. We recommend reaching out to Epson customer support or visiting an authorized repair shop for further help.
