The use of the destination list can be restricted separately under the scanner function.
Restrict Use of Destinations
You can prohibit the sending of scanned documents to addresses other than those registered in the Address Book. By enabling this, you can prohibit users from manually entering the parties’ e-mail address or folder destinations.
Restrict Adding of User Destinations
By using [Prg. Dest.], you can prohibit the addresses manually entered for sending scanned documents from being registered to the Address Book. Also, with this setting, only the user administrator can register new users in the Address Book and change the passwords and other information of existing registered users. In addition, even if you set these functions to [On], the user registered as a destination can change their password. Only the user administrator can change items other than the password.
