Protecting the Communication Path via a
Device Certificate
This printer can protect its communication path and establish encrypted communications using SSL/TLS,
IPsec, or IEEE 802.1X.
To use these protocols, it is necessary to create and install a device certificate for the printer in advance.
The following types of device certificate can be used:
•
Self-signed certificate created by the printer
• Certificate issued by a certificate authority
• The administrator is required to manage the expiration of certificates and renew the certificates
before they expire.
•
The administrator is required to check that the issuer of the certificate is valid.
• If SHA256 or SHA512 is selected as the "Algorithm Signature" of the device certificate, Windows
XP SP3 or later is required to connect the device using Internet Explorer 6.0.
