For the past several months, I have tried setting up my MF644CDW to scan to email. I've followed the instructions to the best of my ability, and read a number of posts on here... and yet, I'm still stuck. Turning to this forum in the hopes someone has cracked the code.
Here's what I've done so far:
- Using RemoteUI, gone to Settings & Registration > Network Settings > Port Number Settings
- I set the SMTP port to 587
- Using RemoteUI, gone to Settings & Registration > TX Settings > E-Mail/I-Fax Settings
- SMTP server: smtp.gmail.com
- E-mail address: (my username)@gmail.com
- Password: (my gmail password)
- Use SMTP authentication (SMTP Auth): checked yes
- Username: (my username)@gmail.com
- Use TLS for SMTP: checked yes
- On Gmail itself (a free personal account, if it matters...) I enabled "less secure apps"
Here's what happens when I try to Scan to E-mail:
- Very quickly, after scanning a document, the printer warms up and prints out a status report. There are not many details: only the number of pages, the destination email, and the word "ERROR"
Did I miss something here? Is there a way to get more information from the printer about what the error actually is - is it an authentication error, something else?
Appreciate any pointers you guys have. Going crazy here...
Solved! Go to Solution.

Worked like a charm on my MF642Cdw.
Initially I couldn't see the Network settings, but when I signed into the Remote UI as the Manager, it was all there.
Thanks so much.

Thanks for helping, I just hope this would have worked with my MF650C. For some reason I still get #752 errors and long time outs when trying something.

Thanks for joining the conversation, jlap777! It sounds like you've got both a different printer and a different error message than what this thread is about. If you need help, we recommend starting a new thread dedicated to your issue. To do that, just click HERE.

I have a MF733CDW and used to use Gmail to send scans but it stopped months ago. I tried using the fix above but got stuck at this step. There is no "Select App" or "App password' section anywhere in my Google acct that I can find. What am I missing?
- Click on 'App Passwords' to setup a password for your Canon. You may have to sign into your Google account again. 7- Under the 'Select App' down arrow, select 'Other (custom)'

Hello. This had worked for me in the past. However, it scan to email has recently stopped working. I have tried creating a new password on google. I have used lower case, upper case, spaces, and no spaces for the password, but it is still not working. I also switched the port from 465 to 587, and changed it back, but i am still getting the #802 error code. Does anyone have a solution to this if all instructions have been followed? Thank you.
