We recommend that after installing the self-signed certificate or device certificate from a private certificate authority on the main unit and enabling SSL/TLS (communication encryption), you instruct users to install the certificate on their computers. Installation of the certificate is especially necessary for users who want to print via IPP-SSL from Windows Vista/7/8, Windows Server 2008/2008 R2/2012. The network administrator must instruct each user to install the certificate.
Select [Trusted Root Certification Authorities] for the certificate store location when accessing the machine by IPP.
Take the appropriate steps when you receive a user's inquiry concerning problems such as an expired certificate.
If a certificate issued by a certificate authority is installed on the machine, check the certificate store location with the certificate authority.
To change the host name or IP address in [Common Name] of the device certificate when using the operating system's standard IPP port under Windows Vista/7/8 or Windows Server 2008/2008 R2/2012, delete any previously configured PC printer beforehand and install it again after changing [Common Name]. Also, to change the user authentication settings (login user name and password), delete any previously configured PC printer beforehand and install it again after changing the user authentication settings.
