This shouldn't be this hard. I have MF741Cdw connected via WiFi to Windows 10 Educational computer. I have removed the printer from Printers and reinstalled the 64bit drivers dated 8/17/2020 from Canon support website. Firewall has made necessary adjustments. I set up a new shared folder and a new user member of Administrators with full control for said folder. I've used Remote UI to create Address Book entry for scan to file and scan to email and neither works. Error #806 for the former and #839 for the latter.
I've used Send Settings to make another Address Book entry for each, but to the Public folder. These don't work either.
I've enabled SMB 1.0/CIFS File Sharing Support but not SNTP.
IPv6 is off.
What needs to be changed for this to work?
