Thanks Mattias for the information about the error and the link to the AppleDev page. I could now use some direction about what needs to be done to get things fixed. I have checked the scanner to make sure it works, checked the USB cable. I have uninstalled and reinstalled both the SANE, Twain interface, and the needed libraries. I have Uninstalled the Epson Scanner Utilities and reinstalled. I have tried both applications installed. I still get the same errors. I am at a loss also, as to why for weeks there were no issues. Nothing had change on the system. The system is in a controlled enviroment. Thanks again for your help. Brandon
