2.12.3 Setting the Overwrite HDD Data
Setting the Overwrite HDD Data function allows data stored in the HDD to be deleted at such timing as the
end of the print cycle by writing specific data over the data that is no longer required. By deleting residual
data that is no longer necessary, data leakage can be prevented from occurring.
The following types of data are subject to the Overwrite HDD Data function:
- Copy, scan, print, or fax job data that is no longer necessary
- PC print job data (direct print, PS print) that is no longer necessary
- Data that is no longer necessary as a result of the data being specified to be deleted
Data stored in the HDD is to be deleted at the following timing:
- At the end (including an end as a result of cancellation) of a copy, scan, print, or fax job performed by
a user who has been authenticated by User Authentication
- A job is deleted by the administrator or a user (who has been authenticated by User Authentication)
- A document in a Box is deleted by the administrator or a user (who has been authenticated by User
Authentication)
- A document is deleted in a Box through Delete User Box
- A document is automatically deleted after the lapse of a predetermined period of time set in the ma-
chine

Reference
- If a job being processed is abnormally terminated, the residual data is deleted through Overwrite HDD
Data.
- If the machine is turned off during an Overwrite HDD Data sequence, the Overwrite HDD Data sequence
is resumed automatically after the machine is turned on again.
- If an Overwrite HDD Data sequence being performed is interrupted by, for example, a fault, a response
is detected at 30-sec. intervals and the Overwrite HDD Data sequence, if found interrupted, is resumed
automatically.

it is absolutely necessary to leave the machine, be sure first to log off from the Administrator Settings.

in a backup medium in advance. Execution of HDD Format will also reset the setting values of different
functions to the default values. Set the Enhanced Security Mode to [ON] again. For the functions whose
settings are reset to the default values, see page 2-10.
