The most common reason is old or missing drivers, but other reasons may include wrong network settings, firewall blocking, or incorrect USB connections. In this article, we will discuss different solutions to solve this problem.
1. Run Scanner Software with Administrative Privileges
Giving the scanner software administrative rights can help overcome system limits that stop it from accessing needed resources. Most operating systems block certain tasks for safety reasons, and scanning, which connects external hardware to the system, often needs higher permissions. Running the software as an administrator lets it do its job without problems, helping to fix communication issues between the scanner and the PC.
2. Fix Wireless Connection
To address communication errors, ensure your computer and scanner have a stable wireless connection. If the IP address changes or is incorrect, the scanner might not be detected. Update the IP address in the Epson Scan settings to help your computer connect directly with the scanner, allowing scanning to potentially work more smoothly.
3. Use a Shorter USB Cable
If you’re having communication issues with your Epson scanner, try using a shorter USB cable. Longer cables can lead to signal interference or data loss, affecting the scanner’s connection to your computer. A shorter cable can reduce these disruptions and may stabilize the connection.
4. Restart Shell Hardware Detection
The Shell Hardware Detection service helps your computer detect devices like scanners and printers. If there’s a problem with this service, your scanner might not be detected. You can try restarting the service and reconnecting the scanner to see if that helps.
5. Turning off Password Protected Sharing
Password-protected sharing increases network security by requiring a password for access but can block scanner connections on the same network. Turning off this feature can help the scanner connect more easily. If this works, you can re-enable it later if needed. Also, make sure Printer Discovery is active so the scanner is recognized properly.
6. Change from LPT1 to USB 001 Virtual Printer Port
Older technology, like Line Print Terminals (LPT), was once used for connecting printers and scanners to computers. Today, USB connections are more common. Changing the printer’s port from LPT to USB might help, especially for users who have encountered scanner issues after upgrading to Windows 10.
7. Reset Windows Image Acquisition (WIA) Service
The Windows Image Acquisition service is important for capturing images when you scan documents on your computer. It allows graphics software to work with devices like scanners. If there’s a problem with this service, it can disrupt scanning or cause errors. Resetting the service can often fix these issues without updating the drivers
8. Update Scanner Drivers
If none of the previous solutions work, try updating the scanner drivers. Visit the manufacturer’s website and download the latest drivers for your specific scanner model. You can find the model number on the front of the device or its packaging. Using outdated or incorrect drivers can cause communication issues between your computer and the scanner, leading to errors or malfunctions. Updating to the latest drivers can improve compatibility and functionality, which may resolve these problems.
