My I-Sensys MF643Cdw continually returns an error code of #806 "The user name or password for sending to the file server or the address for sending by E-mail/I-fax may be incorrect".
I have followed instructions and watched numerous YouTube videos. I am quite certain I have properly configured the printer, and yet I still get the problem. I believe it may have to do with changes in Google app/security protocols.
Any suggestions?
