1.2 Security Functions

Setting the Enhanced Security Mode to [ON] will validate the security function of this machine. For details of the settings of different security functions to be changed by turning [ON] the Enhanced Security Mode, see page 2-10.

A password that can be set must the Password Rules. The machine does not accept setting of an easily decipherable password. For details of the Password Rules, see page 1-8.

If a wrong password is entered, during password authentication, a predetermined number of times (once to three times) or more set by the administrator of the machine, the machine determines that it is unauthorized access through Prohibited Functions When Authentication Error, prohibiting any further entry of the password. By prohibiting the password entry operation, the machine prevents unauthorized use or removal of data, thereby ensuring secured used of the machine.

By setting the Encryption Key, the data saved in the HDD is encrypted, thereby protecting the data in the HDD. Note, however, that the Encryption Key does not prevent the HDD from being physically removed. Make sure of a good operation control.

When the machine is to be discarded or use of a leased machine is terminated at the end of the leasing contract, the Overwrite All Data function overwrites and erases all data stored in all spaces of the HDD. The function also resets all passwords saved in the memory area on the MFP board and the SSD board to factory settings, preventing data from leaking. For details of the Overwrite All Data function, see page 2-27. For details of items to be cleared by Overwrite All Data function, see page 1-8.

Check Count Clear Conditions

The following are the conditions for clearing or resetting the check count of the number of wrong entries at the time of authentication by the Enhanced Security Mode.
