If your Epson scanner not working, it is usually caused by connection issues, outdated drivers, or incorrect scanner settings. A loose USB cable or unstable WiFi connection can prevent the scanner from communicating with your computer. In many cases, an outdated or corrupted driver is the main reason the Epson scanner not working on Windows or Mac.
Another common cause is disabled scanner services or conflicts after a system update. To fix the issue, check all cable connections, restart the printer and computer, update the Epson scanner driver, and ensure the correct scanner is selected in the scanning software. These steps usually restore normal scanning functionality.
