2.6

Preventing unauthorized access

When a log-on to the administrator mode becomes successful, the machine enables setting of the operation

of Prohibited Functions. The machine takes a count of the cumulative number of unsuccessful accesses from

each interface to the administrator authentication, user authentication, and user box authentication to pro-

hibit the authentication operation.

Either [Mode 1] or [Mode 2] can be selected for Prohibited Functions. 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.

NOTICE

If the access lock state of the Administrator Authentication is canceled by the Service Engineer, the setting of

the Release Time Settings function is not applied.

Making any of the following settings when the [Enhanced Security Mode] is set to [ON] will cancel the [En-

hanced Security Mode].

-

Changing [Prohibited Functions] to [Mode 1]

-

Changing the check count for [Prohibited Functions] to four times or more

-

Setting [Release Time Settings] to 1 to 4 min.
