4 Xerox® D95/D110/D125 Copier/Printer Security Function Supplementary GuideStarting Use of the Data EncryptionFeature and Changing the SettingsWhen data encryption is started or ended, or when the encryption key is changed, the machinemust be restarted. The corresponding recording area (the Hard Disk) is reformatted whenrestarting. In this case, the previous data is not guaranteed.The recording area stores the following data:• Spooled print data• Print data including the secure print and sample print• Forms for the form overlay feature• Folder and job flow sheet settings (Folder name, passcode, etc.)• Files in Folder• Address book dataImportant:Be sure to save all necessary settings and files before starting to use the data encryptionfeature or changing the settings.An error occurs if the connected hard disk does not match the encryption settings.Use of the Overwrite Hard DiskIn order to protect the data stored on the hard disk from unauthorized retrieval, you can setthe overwrite conditions to apply them to the data stored on the hard disk.You can select the number of overwrite passes as one or three times. When [1 Overwrite] isselected, “0” is written to the disk area. [3 Overwrites] ensures higher security than [1Overwrite].The feature also overwrites temporarily saved data such as copy documents.Important:If the machine is powered off during the overwriting operation, unfinished files may remain onthe hard disk. When the power is restored, the overwriting operation will resume with theunfinished files remaining on the hard disk.
