After installing the device certificate in the printer, enable the SSL/TLS setting.
This procedure is used for a self-signed certificate or a certificate issued by a certificate authority.
Log in as the network administrator from Web Image Monitor.
Point to [Device Management], and then click [Configuration].
Click [SSL/TLS] under "Security".
Click [Active] for the protocol version used in "SSL/TLS".
Select the encryption communication mode for "Permit SSL/TLS Communication".
If you want to disable a protocol, click [Inactive] next to "TLS1.2", "TLS1.1", "TLS1.0", or "SSL3.0".
At least one of these protocols must be enabled.
Some combinations of the TLS and SSL versions are invalid for SSL communications. If an invalid combination is selected, the “An invalid combination of protocols has been specified in [SSL/TLS Version].” message appears. Select another combination.
Under "Encryption Strength Setting", specify the strength of encryption to be applied for "AES", "3DES", and/or "RC4". You must select at least one check box.
Note that the availability of encryption strengths will vary depending on the settings you have specified for "TLS1.2", "TLS1.1", "TLS1.0", or "SSL3.0".
Click [OK].
“Updating...” appears. Wait for about one or two minutes, and then click [OK].
If the previous screen does not reappear after you click [OK], wait for a while, and then click the web browser's refresh button.
Log out.
If you set "Permit SSL/TLS Communication" to [Ciphertext Only], communication will not be possible if you select a protocol that does not support a Web browser, or specify an encryption strength setting only. If this is the case, enable communication by setting [Permit SSL/TLS Communication] to [Ciphertext/Cleartext] using the printer's control panel, and then specify the correct protocol and encryption strength.
The SSL/TLS version and encryption strength settings can be changed, even under [Network Security].
Depending on the states you specify for "TLS1.2", "TLS1.1", "TLS1.0", and "SSL3.0", the printer might not be able to connect to an external LDAP server.
The following types of communication and data are always encrypted by SSL3.0: communication via @Remote and logs transferred to Remote Communication Gate S.
