Scanning via FTP-server on Xerox 6604

Hello!

I can not configure the scanning of documents on my Xerox 6604 on the FTP server. Through the Web interface, I made the following settings, but when I try to scan, my Xerox 6604 writes an "incorrect login" error. The same error occurs when I try to connect to the built-in FTP server through the Total Commander or via the web interface.

Please help setup the FTP server on the machine.
