MF642C - scan to email stopped working after firmware update

hirenushah — Tue, 13 Dec 2022 02:16:55 GMT

Scan to email stopped working today on MF642C after firmware update from cannon. It used to work fine until this morning.

I had below gmail setting that was working

E-Mail/I-Fax Settings
SMTP Server: smtp.gmail.com
E-Mail Address: user@gmail.com
POP RX: Off
Authentication/Encryption Settings
POP Authentication Before Sending: Off
SMTP Authentication (SMTP AUTH): On
User Name: user@gmail.com
Password: Set.
Use TLS for SMTP: On
Verify Certificate: Off
Use TLS for POP: Off

And SMTP port is 587 under port number settings

It seems firmware messed up

Greetings,

Settings look good. Try with port 465 and see if that makes any difference.

I tried with port 465 but same error #752.

Is there any way to get back to previous firmware?
