My Epson scanner is connected properly, but I still get the communication error. What should I do?

If the physical connection seems fine, the issue may be software-related. Ensure that the correct Epson scanner driver is installed and up-to-date. Check your device manager (Windows) or system information (macOS) to see if the scanner is recognized. Antivirus or firewall software might be blocking the connection; temporarily disable them for testing purposes. A conflict with other installed scanner software could also be the cause.
