 Simple Network Time Protocol (SNTP) enables you to adjust the system clock by
using the time server on the network. The protocol is typically used for synchronizingthe machine and a server. The time is adjusted based on Coordinated Universal Time
(UTC), so specify the time zone setting before  con4guring SNTP ( 
Date/Time
Settings(P.490) ). SNTP settings can be  speci4ed via the Remote UI.
	The SNTP of the machine supports both NTP (version 3) and SNTP (versions 3 and 4) servers.

							MonitoringandControllingtheMachinewithSNMP
1469-078
Simple Network Management Protocol (SNMP) is a protocol for monitoring and controlling communication devices in a
network by using Management Information Base (MIB). The machine supports SNMPv1 and security-enhanced SNMPv3. You can check the status of the machine from a computer when you print documents or use the Remote UI.
You can enable either SNMPv1 or SNMPv3, or both at the same time. Specify the settings for each version to suit your
network environment and the purpose of use.
SNMPv1
SNMPv1 uses information called "community" to  de4ne the scope of SNMP communication. Because this
information is exposed to the network in plain text, your network will be vulnerable to attacks. If you want to
ensure network security, disable SNMPv1 and use SNMPv3.
SNMPv3
With SNMPv3, you can implement network device management that is protected by robust security features.Note that TLS must be enabled for the Remote UI before  con4guring SNMPv3 ( 
EnablingTLSEncrypted
CommunicationfortheRemoteUI(P.426) ).
	The machine does not support the trap  noti4cation feature of SNMP.
	 To change the port number of SNMP, see 
ChangingPortNumbers(P.409) .
	 SNMP management software, when installed on a computer on the network, enables you to  con4gure,
monitor, and control the machine remotely from the computer. For more information, see the instruction manuals for your management software.1StarttheRemoteUIandlogoninSystemManagermode.StartingRemote

[MIBAccessPermission@
For each community, select [Read/Write] or [Read Only] for the access privileges to MIB objects.
[Read/Write]Permits both viewing and changing the values of MIB objects.[Read Only]Permits only viewing the values of MIB objects.

[AuthenticationAlgorithm@
If you selected [Authentication On/Encryption On] or [Authentication On/Encryption Off] for [Security
Settings], select the algorithm that corresponds to your environment.
[EncryptionAlgorithm@
If you selected [Authentication On/Encryption On] for [Security Settings], select the algorithm that corresponds to your environment.
[Set/ChangePassword@
To set or change the password, select the check box and enter between 6 and 16 alphanumeric characters
for the password in the [Authentication Password] or [Encryption Password] text box. For  con4rmation, enter
the same password in the  >Con4rm@ text box. Passwords can be set independently for authentication and
encryption algorithms.
[ContextName1@/[ContextName2@/[ContextName3@
Enter up to 32 alphanumeric characters for the context name. Up to three context names can be registered.

								With SNMP, the printer management information, such as printing protocols and printer ports, can be
monitored and obtained regularly from a computer on the network.
[AcquirePrinterManagementInformationfromHost@
Select the check box to enable monitoring of the printer management information of the machine via SNMP.
To disable monitoring of the printer management information, clear the check box.

	 Some of the functions of the machine become unavailable, such as obtaining machine information via the
printer driver.
Usingtheoperationpanel 	 You can also specify SNMPv1 settings and enable/disable SNMPv3 settings from the  in the 
screen. 
SNMPSettings(P.480)
EnablingBothSNMPv1andSNMPv3	 If both versions of SNMP are enabled, it is recommended that MIB access permission in SNMPv1 be set to
[Read Only]. MIB access permission can be set independently in SNMPv1 and SNMPv3 (and for each user in SNMPv3). Selecting [Read/Write] (full access permission) in SNMPv1 negates the robust security featuresthat characterize SNMPv3 because most of the machine settings can then be controlled with SNMPv1.

Con4dential  information is handled by information devices everywhere, including computers and printers, and any of
these devices may become a target for malicious third parties at anytime. Attackers may directly gain unauthorized
access to your devices, or indirectly take advantage of negligence or improper use. Either way, you may incur unanticipated losses when your  con4dential information is leaked. To counter these risks, the machine is equipped
with a variety of security functions. Set the necessary  con4guration depending on your network environment.
	You can  con4gure  the best security system by building an environment that inhibits access to printers on
your in-house network via the Internet and using such environment together with the machine's security
features.
