User Settings For Ssl (Secure Sockets Layer); Setting The Ssl/Tls Encryption Mode - Ricoh Aficio SP 5200DN Operation And Use Manual

User Settings for SSL (Secure Sockets Layer)

We recommend that after installing the self-signed certificate or device certificate from a private certificate
authority on the main unit and enabling SSL (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 or Windows Server 2008/2008 R2. The network administrator
must instruct each user to install the certificate.
• Take the appropriate steps when you receive a user's inquiry concerning problems such as an expired
certificate.
• For details about how to install the certificate and about where to store the certificate when accessing
the printer using IPP, see Web Image Monitor Help.
• If a certificate issued by a certificate authority is installed in the printer, confirm the certificate store
location with the certificate authority.
• Printing via the standard IPP port under Windows Vista/7 or Windows Server 2008/2008 R2 is
possible only after the hostname or IP address is specified in the device certificate's [Common Name]
setting. If the host name or IP address has changed, the user must delete the printer installed on the
client computer. The printer must be reinstalled if the client computer's device certificate has been
updated. Also, if a user's authentication information (login user name and password) has changed,
the printer must be deleted, then the user's information settings must be updated, and then the printer
must be reinstalled.
