Enabling/Disabling Protocols
This can be specified by the network administrator.
Specify whether to enable or disable the function for each protocol. By making this setting, you can specify
which protocols are available and so prevent unauthorized access over the network. Network settings can
be specified on the control panel, or using Web Image Monitor, telnet. For details about making settings
using telnet, see "Remote Maintenance by telnet", Network Guide. To disable SMTP on Web Image
Monitor, in E-mail settings, set the protocol to anything other than SMTP. For details, see Web Image
Monitor Help.
For details about logging on and logging off with administrator authentication, see "Logging on Using
Administrator Authentication", "Logging off Using Administrator Authentication".
