WorkCentre 6515 SMTP and scanning Issue


For several years my 6515 has been able to scan to email and all of a sudden the other day it just stopped. 

I checked the SMTP settings and they were all right but I kept getting a login error when I ran the SMTP test.  I then proceeded to wipe the machine and start from scratch, it now passes the SMTP test but when I try and end and scan to email it just fails with "Completed with an Error (016-764) : SMTP Server Connection Error.

Does anyone have any ideas?  I can post screenshots if needed.

Re: WorkCentre 6515 SMTP and scanning Issue

I have been experiencing the same problem on the same printer and am also strongly interested in a solution!

I am trying to connect to Gmail ( / starttls / 587 / smtp auth). Tried also with 465 and without smtp authentification.

Would be great if anybody could help!

Re: WorkCentre 6515 SMTP and scanning Issue

Go back over the SMTP settings and do it without using Chrome/Edge browser .

Also, make sure the firmware is up to date, because Office365 and Gmail both started a rolling update across their servers in January that has been affecting older firmwares, and may have been the cause of the initial issue you had.

WC6515 firmware

Windows tool

Mac firmware installer

The browser issue will cause the highlighted portions to not actually apply, even though it will state they did.
