Administrator Operations 2
2.3 Preventing Unauthorized Access
When access by the Administrator of the machine through the Administrator Settings via the control panel is
authenticated, the machine enables setting of the operation of Prohibited Functions When Authentication
Error. The machine then takes a count of the number of unsuccessful accesses to the Administrator Settings,
User Authentication, Account Track, SNMP authentication, Secure Print authentication, and User Box
authentication to prohibit the authentication operation.
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], it is prohibited to change the setting from
[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 Settings is set into the access lock state, the main power switch is turned off and on
and, after the lapse of a predetermined period of time after the machine is turned on again, the access lock
state of the Administrator Settings is canceled. The Release Time Settings function allows the period of time,
after the lapse of which the access lock state of the Administrator Settings 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.

Note
If the access lock state of the Administrator Settings is canceled by the Service Engineer, the setting of
the Release Time Settings function is not applied.

it is absolutely necessary to leave the machine, be sure first to log off from the Administrator Settings.
Release Time can be set to any value between 1 min. and 60 min. in 1-min. increments. An input data
error message appears when any value falling outside the range of 1 to 60 min. is set. Enter the correct
Release Time again.
In the Enhanced Security Mode, Release Time less than 5 min. cannot be set.

Mode 2 If authentication fails, the authentication operation (entry of the password) is prohibited for 5 sec.
The number of times, in which authentication fails, is also counted and, when the failure count
reaches a predetermined value, the authentication operation is prohibited and the machine is set
into an access lock state.
