Diagnosing and Resolving the "Selected Scanner Could Not Be Found" Error for Epson XP-3100 Series Scanner in NAPS2 using CMD/PowerShell

If you are having trouble with your Epson XP-3100 Series scanner connected via Wi-Fi, and you encounter the error "Error: selected scanner could not be found" when trying to scan a new document using NAPS2, this article will guide you through the process of diagnosing and resolving the issue.

Prerequisites

Before proceeding, make sure you have the following tools installed:

• NAPS2 (https://www.naps2.com/)
• CMD or PowerShell (included with Windows operating system)

Checking the Connection

First, ensure that your Epson XP-3100 Series scanner is properly connected to your Wi-Fi network. You can do this by checking the network settings on the scanner's control panel or in the printer software on your computer.

Finding the Scanner in NAPS2

Next, open NAPS2 and go to the "Scanner" tab. If your scanner is not listed, click on "Rescan" to search for it again. If it still does not appear, try restarting NAPS2 and your computer before attempting to rescan.

Using CMD/PowerShell to Diagnose the Issue

If your scanner is still not being detected by NAPS2, you can use CMD or PowerShell to diagnose the issue. Follow these steps:

1. Press the Windows key + X and select "Command Prompt (Admin)" or "PowerShell (Admin)"
2. Type the following command and press Enter: wmic printer get name, deviceid, portname
3. Look for your Epson XP-3100 Series scanner in the list. If it is not present, the scanner is not properly connected to your computer.
4. If the scanner is present, take note of the "PortName" value. This is the port that NAPS2 is using to communicate with the scanner.

Resolving the Issue

If your scanner is not present in the list generated by the CMD/PowerShell command, try the following steps:

1. Unplug the scanner from the power source and wait for 30 seconds before plugging it back in.
2. Reconnect the scanner to your Wi-Fi network.
3. Restart your computer.
4. Rescan for the scanner in NAPS2.

If the scanner is present in the list generated by the CMD/PowerShell command, but NAPS2 is still unable to detect it, try the following steps:

1. Make sure the scanner is turned on and connected to the same network as your computer.
2. Check the port name in NAPS2 and compare it to the port name generated by the CMD/PowerShell command. If they do not match, change the port name in NAPS2 to match the one generated by the command.
3. Restart NAPS2 and try scanning again.
