Enabling and Disabling Protocols

This can be specified by the network administrator. For details about logging in and logging out with
administrator authentication, see p.30 "Logging in Using Administrator Authentication" and p.32 "Logging
out Using Administrator Authentication".
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 Using telnet", Network and System Settings Reference. 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.
