Unable to write to file
I had the same problem and fixed mine without re installation. Even though the error does not indicate it very well, the application could not write to the destination. The EPSON Scan application has a destination in two places. One under configuration, in my case, correct. However, a more buried location, next to the Scan button, press the arrow to edit more settings. There, you will find another destination, in my case, incorrect ( a folder that did not exist). Change the setting to a folder that does exist, it should work. Check out my fix here, detailed with pictures. Thank you. Hope this helps someone.
