I am trying to setup Scan to email and am getting error 17-772 and cannot find anything on this errot. I am trying to use the Spectrum ISP SMTP. Tried port 993 and 587 with SSL on mail.brighthouse.com.
What model Xerox device do you have?
In case anyone stumbles upon this, I had the same error, but when trying to scan to SMB folder (network share on a computer). I was using a Xerox WorkCentre 6515. Eventually I ended up using WireShark to investigate, and noticed that the printer wasn't even trying to send traffic out after scanning -- it just errored immediately when trying to create the PDF, and spit out error 017-772 for some reason.
In my case, I had to Apps > Scan To section, and turned off "Searchable Text", "Auto Orientation", and "Remove Blank Pages". It started working, so I went back in and turned them back on, one at a time. But... it kept working.
I'm guessing there's some sort of underlying bug somewhere that gets "reset" when you do this, but, I'm happy with the result.
