2.4 Preventing Unauthorized Access
When a log-on to the Administrator Mode becomes successful, the machine enables setting of the operation
of Prohibited Functions When Authentication Error. The machine takes a count of the cumulative number of
unsuccessful accesses from each interface to the Administrator Authentication, User Authentication, Ac-
count Track, Secure Print authentication, and User Box authentication to prohibit the authentication opera-
tion.
Either [Mode 1] or [Mode 2] can be selected for Prohibited Functions When Authentication Error. The factory
setting is [Mode 1]. If the Enhanced Security Mode is set to [ON], the setting is changed to [Mode 2] (check
count: three times). It is nonetheless possible to change the check count to select from among once, twice,
or three times.
If [Mode 2] is selected, the Release Time Settings function is enabled. When the Administrator Authentication
is set into the access lock state, the main power switch is turned off and on and, after the lapse of a prede-
termined period of time after the machine is turned on again, the access lock state of the Administrator Au-
thentication is canceled. The Release Time Settings function allows the period of time, after the lapse of
which the access lock state of the Administrator Authentication is canceled, to be set in the range between
1 and 60 min. The factory setting is 5 min. For details of each mode, see the table below.
