I searched the Knowledge Base and found THIS solution you can try to resolve your scanning issue.
I met a question that I scan a paper,it display error,follow as
Job failed. No messages were sent, Could not login to the sending mail server (SMTP). Check your user name and password provided or contact your System Administrator
and I do what follow as line,https://forum.support.xerox.com/t5/Copying-Faxing-Scanning/C8055-scan-to-email-test-successful-but-c...but it does not work.
I need to scan any paper no login.
Do you know how to do it?
Thank's for your feedback
