MF743cdw Scan to Destination (SMB) not working


For the life of me I can't seem to get the Scan to Destination to work consistently.

I have a NAS that I want to scan the files to, I have the share setup, password correct, can connect from 2 different computers to it, it even worked 2 times from the printer, but nothing changed just some time passed and it doesn't work. I tried restarting both he NAS and the Printer but nothing works. Status code. 801

HELP ME!!!!!

I also thought this had an application library app for cloud apps like google drive/dropbox/etc, however I don't see that where is that, I would love to be able to scan to dropbox or google drive! PLEASE HELP!!!! I really need this to work!

The 801 error would point to a communication or setting issue The error would come up if one of the issues below occurs.

  1. When communicating with an SMTP server to send an e-mail/I-Fax, a timeout error occurred from the server.
    Check whether SMTP is running on the network correctly.
  2. When communicating with the SMTP server, an error returned from the server.
    Check whether the SMTP server is set correctly.
  3.  A destination is not set correctly.
  4. When storing a scanned original into the shared folder, an error occurred from the folder.

In this situation, I would suggest contacting support over the phone at 1-800-652-2666. Our agents would be happy to assist with checking the settings/network environment to see what is causing the issue.

I tried calling in they were not helpful at all. They barely understood the question and their solutions were laughable. They basically told me they never setup network shares and that they only had information to have the share on a windows computer and specifically on its C: drive.  Canon needs to get better support, and better knowledge about its products out to its support members and customer.

Why isn't there a way to test to see if the connection is made to the server from inside the web portal on the printer. It would be easy to "test the connection" from there. Instead you have to make settings, then go to the printer and scan something and then wait to find out your connection didn't work. At least make it a little easier to troubleshoot it for your customers if you aren't going to give them ANY information about how to set it up!
