C5507-36 Overwrite Temporary Data
The setting for overwriting data on the hard disk can be specified. (The de-
fault setting is “Mode 1”.)
This machine destroys data by overwriting all data in the entire area where 
an image was stored when that image data on the hard disk is considered 
unnecessary. In addition, destroying the structure of data other than image 
data prevents the disclosure of the data in case the hard disk is stolen.
