(With apologies to the many other similar threads... I've read them all, and still having trouble)
I've put together a ton of screenshots that show the errors, my settings, and what I've already tried, take a look.
Have a MF8580CDW, connected to wifi.
Trying to use scan-to-email, with a GMail account.
But it gives error #752 every time.
Background: It was working great for a long time, and the error began recently when someone pulled out the power cord, and the printer lost all its settings. Now I can't get it to work again.
Troubleshoting done so far:
Yes, the printer is connected to internet.
Yes, I'm pretty sure I have typed in the server name and username correctly.
Yes, the gmail account has "allow less secure apps" turned on.
Yes, I have changed the SMTP port number. Tried 25, 465, and 587. All give same error - Error #752.
Please take a look at screenshots of everything: screenshots.
Can anyone suggest additional troubleshooting? Thanks.
