Overwrite Hard Disk
Select whether or not to carry out hard disk overwrite erasing. If you overwrite the hard disk,
you can select whether to overwrite once or three times.
When copy, fax, scan, or print processing is completed, the data is deleted from the hard disk
and the area on which the deleted data was stored is automatically overwritten with blank
data. This feature prevents unauthorized retrieval or restoration of the data recorded on the
hard disk. It also applies to copy source, and other information stored temporarily by the
system.
The following option can be configured.
Number of Overwrites
Important •
If the machine is powered off during the overwriting operation, unfinished files may remain
on the hard disk. The overwriting operation will resume if you power the machine on again
with the unfinished files remaining on the hard disk.
•
The data is erased by overwriting once, but overwriting three times makes it even more
definite that the data cannot be recovered. It does, however, take longer.
•
During the overwriting process, processing of normal operations may be slowed down.
Note
•
An optional package is required to use this feature. For more information, contact our
Customer Support Center.
For information about how to check the status during the overwriting process, refer to "Overwrite Hard
Disk" (P.67).

will not be able to recover in case of malfunction.
