Deleting Data on the Hard Disk
To use this function, the optional DataOverwriteSecurity Unit must be installed.
To prevent data on the hard disk being leaked before disposing of the printer,
you can overwrite all data stored on the hard disk. You can also automatically
overwrite temporarily-stored data.
❖Auto Erase Memory Setting
To erase selected data on the hard disk, specify [Auto Erase Memory Setting].
❖Erase All Memory
To erase all the data on the hard disk, using [Erase All Memory].
❖Methods of Erasing the Data
You can select the method of erasing the data from the following:
The default is “NSA”.
*1 National Security Agency
*2 Department of Defense
Note
❒Depending on the hard disk capacity and the method of erasing the data, this
action may take a few hours. Once you start the Erase All Memory function,
no other printer operation is possible until the function completes or you quit
the function.
❒The printer’s hard disk lets you store data under the printer.
NSA
*1
Overwrites the data on the hard disk twice with random numbers
and once with zeros.
DoD
*2
Overwrites the data with a number, its complement, and random
numbers, and then checks the result.
Random Numbers Overwrites the data with random numbers the specified number of
times.
You can specify between 1 and 9 as the number of times the data is
overwritten with random numbers. The default is 3 times.

4
Auto Erase Memory Setting
This can be specified by the machine administrator.
A print data sent from a printer driver is temporarily stored on the printer's hard
disk.
Even after the job is completed, it remains in the hard disk as temporary data.
Auto Erase Memory erases the temporary data on the hard disk by writing over it.
Overwriting starts automatically once the job is completed.
The Printer functions take priority over the Auto Erase Memory function. If a
print job is in progress, overwriting will only be done after the job is completed.
Preparation

are displayed before performing the operation. See p.2 “Displaying adminis-
trator menus”.
