Setting security using the Embedded Web Server (EWS)
You can enhance the security of network communications and device configuration by using the advanced security options. 
These features are available through the Web page of the device.
Setting the system password
Setting the system password protects configuration of the Embedded Web Server. A system password is also required for 
Secure mode and confidential communication with MVP.
To set the system password:
1Open your Web browser. In the address line, enter the IP address of the printer you want to configure using the 
for mat: http: //ip_address/.
2Click Configuration.

3Under Other Settings, click Security.
4Click Create Password if one has not been set previously. If a password has been set before, click Change or 
Remove Password.
Using the secure Embedded Web Server
The SSL (Secure Sockets Layer) allows for secure connections to the Web server within the print device. You can connect 
to the Embedded Web Server more securely by connecting to the SSL port instead of the default HTTP port. The SSL port 
connection will encrypt all Web server network communications between the PC and the printer. To connect to the SSL 
port:
Open your Web browser. In the address line, enter the IP address of the printer you want to configure using the format: 
https: //ip_address/.
Supporting SNMPv3 (Simple Network Management Protocol version 3)
SNMPv3 protocol allows for encrypted and authenticated network communications. It also lets the administrator select a 
desired level of security. Prior to use, at least one user name and password must be established from the settings page. To 
configure for SNMPv3 through the Embedded Web Server of the printer:
1Open your Web browser. In the address line, enter the IP address of the printer you want to configure using the 
for mat: http://ip_address/.
2Click Configuration.
3Under Other Settings, click Network/Ports.
4Click SNMP.
SNMPv3 authentication and encryption has three levels of support:
No authentication and no encryption
Authentication with no encryption
Authentication and encryption
Note:Only the selected level and later may be used to communicate.
Supporting IPSec (Internet Protocol Security)
IP Security protocol provides authentication and encryption of communications at the network layer allowing all application 
and network communications over the IP protocol to be secure. IPSec can be set up between the printer and up to five 
hosts, using both IPv4 and IPv6. To configure IPSec through the Embedded Web Server: 
1Open your Web browser. In the address line, enter the IP address of the printer you want to configure using the 
for mat: http://ip_address/.
2Click Configuration.
3Under Other Settings, click Network/Ports.
4Click IPSec.
Two types of authentication are supported for IPSec:
Shared Key Authentication—Any ASCII phrase shared among all the participating hosts. This is the easiest way 
to configure when only a few hosts on the network use IPSec.
Certificate Authentication—Allows any hosts or subnet of hosts to authenticate for IPSec. Each host must have 
a public/private key pair. Validate Peer Certificate is enabled by default, requiring each host to have a signed
