Creating and Installing a Xerox
®
Device Certificate
If you do not have a server functioning as a certificate authority, install a Xerox
®
Device Certificate on
the printer. When you create a Xerox
®
Device Certificate the printer generates a certificate, signs it, and
creates a public key used in SSL encryption. After you install a Xerox
®
Device Certificate on the printer,
install the Generic Xerox
®
Trusted CA Certificate in any device that communicates with the printer.
Examples of other devices include client Web browsers for HTTPS or a RADIUS authentication server for
802.1X. Installing the Generic Xerox
®
Trusted CA Certificate ensures that users can access the printer
using Xerox
®
CentreWare
®
Internet Services, and certificate warning messages do not appear.
Note:
Creating a Xerox
®
Device Certificate is less secure than creating a certificate signed by a
trusted certificate authority.

messages do not appear, install the Generic Xerox
