Administrator Operations Chapter 2

2.11 Overwrite All Data Function

When access to the Administrator Setting mode by the Administrator of the

machine via the control panel is authenticated, the machine enables setting

of the operation of the Overwrite All Data function.

When the machine is to be discarded, or use of a leased machine is termi-

nated at the end of the leasing contract, the Overwrite All Data function over-

writes and erases all data stored in all spaces of the HDD. The function also

resets all passwords saved in the NVRAM to factory settings, preventing leak

of data. For details of items that are cleared by the Overwrite All Data func-

tion, see “Types of Data Cleared by Overwrite All Data Function” on

page 1-12.

The HDD Overwrite Method offers the choice of eight different modes, [Mode

1] through [Mode 8]. Overwrite All Data takes about 30 minutes in [Mode 1]

at the minimum and about 4 hours in [Mode 8] at the maximum.

Reminder

Execution of the Overwrite All Data function not only overwrites and eras-

es all data stored in all spaces of the HDD, but also resets all passwords

to factory settings.
