Hello, I just purchased an MFP M479fdw for the purpose of scanning documents directly to Google Drive. I setup the MFP via the touch screen (ie, without a computer), and it connects to WiFi. I was also successful in logging into the Google Drive app on the MFP. However, when I attempt to scan to Google Drive, the MFP touchscreen shows the error "There was and internal processing error. Please retry or manually check the firmware updates." But there are no updates available when I go to Printer Maintenance in the MFP's Settings.
When I try to go to the Google Drive app again, the MFP touchscreen shows the error "The user [email@example.com] token has expired. Please remove the user and add again." So, then I have to remove my Google account and start all over. I spent hours trying to figure it out and am now at a loss. Any suggestions?
