Ce-00 in mx 2600n - Sharp MX-2700N Color Copier

SOURCE: mx-2300n network error ce-00 when trying to scan

Using Internet Browser access to the Printer/scanner, accessing Network settings, I noticed that the "Connection Test", (below the SMTP Settings), would not go through when SMTP Authentification was set to "ON". Turning it "OFF" allowed the connection test to succeed, but did not change the error code.
However, adding a secondary SMTP Server, allowed it to go through, (leaving SMTP Authentication set to "ON").
Good Luck
