ImageCLASS MF644Cdw Scan to Email 806

zach16smith — Tue, 11 Feb 2025 02:38:31 GMT

So, this has been going on for since about September of 2024. I bought land and wanted to scan all my documents for it and printer wouldn't send the files to gmail. At the time I changed no settings. I have since periodically try fixing this. I followed the manual, watched many and may videos on youtube, browsed reddit and quora and many others including here. Every "solution" hasnt worked. So I will list out what I've tried

Update firmware
reset network and printer (even tho i could still print)
checked emails in address book
made a google app password and tried with and without spaces
unchecked and checked TLS for SMTP
checked SMTP server (smtp.google.com) and (smtp-relay.google.com)
tried 20,465, and 587 for SMTP port numbers
and others i cant think off (except throwing it at a wall, jk i wont......yet)

Please can someone help. I have like 10 people I do taxes for and really need to scan!!!!

Greetings,

An 806 error usually indicates a problem with the destination email address. Either the way it's entered in the address book, or the way it's being typed into the LCD panel.

You do need to supply mail server settings so the printer knows what to do in order to send mail. I have 2 Canon laser printers configured to use Gmail for SMTP.

There's no need to upgrade firmware. It has no bearing on the ability to send email.

To use Gmail.

SMTP Server: smtp.google.com

Username. Full Gmail address

Password. Enter the app password you created without spaces. 16 characters. (Try typing it in). No copy/paste.

TLS check box enabled. Ensure this is under the heading for SMTP TX, not POP

Port: I used 587. Once again.. Make sure you're setting the port for SMTP TX: not POP.

There is a test button on the upper right hand corner where you can test the configuration. This will tell you if the printer can connect to your mail server (Google account) correctly. You must be logged into the remote UI from a PC.

For My Address Book I just entered the addresses under Favorites. They appear on the printer's LCD, or I can enter a recipient's address manually if I don't have an entry.

806 typically indicates a problem with your recipient's email address, but I'd look the whole thing over just to be on the safe side. Sounds like you're really close.

Thanks for getting back to me. So i went through line by line and found that for mail server i had put in smtp.gmail.com. So i changed that to google double checked everything else and tried again. Now i get an 801 error

Hi all,

Curious if you found a fix for this as I’m experiencing the same exact issue. Just bought a

MF654Cdw with pretty much the sole intention of doing scan to email for my business. Ready to return this thing and buy a HP… Any guidance on this is greatly appreciated!

Hi zach35.

Can I ask that you start your own threads so that your issue can receive the visibility it deserves. I realize it's similar to the thread starter, but you have a different model printer, and could be using a different SMTP Mail provider.

It's also not possible for you to mark a thread as solved unless it's your own. This is also helpful for other searching for solutions. When you start your thread, please list the model of your Canon device and the mail service you are using One of us will absolutely respond and try to assist you.

I hope this makes sense, Thanks in advance.

smtp.gmail.com is correct
