Certificates for the Embedded Web Server
Your device includes an HTTPS certificate. The device generates the certificate automatically during device installation. The HTTPS certificate is used to encrypt communications between your computer and the Xerox device.
Note: 
The Embedded Web Server page for your Xerox device can display an error message that the security certificate is not trusted. This configuration does not lessen the security of the communications between your computer and the Xerox device.
To eliminate the connection warning in your Web browser, you can replace the certificate with a signed certificate from a Certificate Authority. For information on obtaining a certificate from a Certificate Authority, contact your Internet Service Provider.
To eliminate the connection warning in your Web browser, you can download the Xerox Root CA certificate from the device Embedded Web Server, then install the certificate on your client.
For information on obtaining, installing, and enabling certificates, refer to the System Administrator Guide at www.xerox.com/office/VLB620docs.
