 If "Update Scheduler" is enabled, the following operations occur:
 Automatic updates start when the scanner is in a standby mode or when no user is
logged in while it is turned on.
Updates are also performed on a specified date and time even with notifications
from the Central Admin Server or in an environment in which Wake On LAN cannot
be used.
 When Wake On LAN is enabled, automatic updates start even if the power is off
 When the setting for an automatic update from the Central Admin Server is
distributed to the scanners, if the update is scheduled to start within ten minutes
after the setting was distributed, the setting will not be applied.
To enable new system settings in an environment where update calls cannot be
issued, scanners must be restarted or logged out. In order to prevent software
updates from running at the same time, enable software update time-period
restrictions. System settings can be updated even when software updates are
restricted. For details, refer to the Scanner Central Admin User's Guide.
 If the scheduled automatic update time is set in both the Central Admin Console
and with the Admin Tool, the most recent settings will be enabled.
