Hi, I have a WorkCentre 6605 which has suddenly stopped scanning to email. We use a gmail account to recieve this but after testing both SSL and TLS gmail settings and updating the firmware I am not any closer to resolving this issue.
Unable to connect to Email SMTP server 016-764 is what appears on the printer's console.
Solved! Go to Solution.
016-764 means it connected but then got an invalid response from the mail server (Printer gets confused and just stops)
So if you get that on the latest firmware, then Google likely changed something on their end that the printer can't do.
Your best bet is to use something like SMTP2Go assuming you have already followed the plethora of gmail topics posted here already
found the problem to be the Gmail account, the computer is in a remote location from our main office and was Google was blocking the other site's IP address, soon as I logged into the account from the other site it prompted me make sure that it was signing in from this site using the recovery email address and the the scan to email functional was restored.
SSL settings: Use StartTSL if available
Email Settings: port 587, SMTP server smtp.gmail.com, I used authenication with the gmail address and password afterwards.
Thanks all that helped
