How can I troubleshoot the 'e581 b319' error if it occurs after a Windows update?

If the error appears after a Windows update, the first step is to check for updated scanner drivers from Epson's website. Reinstalling the drivers, restarting your computer, and temporarily disabling any security software (like firewalls or antivirus) to check for interference are also recommended. Compatibility issues related to the updated Windows version could also exist and Epson might have specific instructions.
