Administrator Operations 2
2.2 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 Er-
ror. The machine then takes a count of the number of unsuccessful accesses to the Administrator Settings
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 [Mode2] is set, the check count can be selected from among once to five times. To
prevent unauthorized access, operate the machine in [Mode2]. If [Mode 2] is selected, the Release Time Set-
tings 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 can-
celed, 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.

Note
Do not leave the machine with the setting screen of Administrator Settings left shown on the display. If
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.
Mode Description
Mode 1 If authentication fails, the authentication operation (entry of the password) is prohibited for 5 sec.
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.
