Fujitsu iScanner fi-6010N Operator's Manual page 134

Automatic updates start when the scanner is in a standby mode or when
HINT no user is logged in while it is turned on.
Even if notifications from the Central Admin Server or Wake-On-LAN can-
not be used, an update can be performed according to the specified date
and time.
If a user is logged in at the scheduled date and time, updates start after
the user has logged out.
It takes approximately 10 minutes to enable this setting. Therefore, make
sure that the scheduled date and time starts at least 10 minutes after the
setting is made.
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.
Select the [Off] button to disable automatic updates.
