202 Xerox CopyCentre/WorkCentre/WorkCentre Pro 123/128 User Guide
Overwrite Hard Disk
Select whether or not to enable overwriting the hard disk. If enabled, random data will 
be written to the disk area released by the data deletion to avoid illegal data retrievals 
from the hard disk. You can select the number of overwrite passes from one time or 
three times. This also overwrites temporarily saved data such as copy documents.
Data Encryption
Select whether to enable encoding when data is saved to RAM, NV-RAM, backed up 
memory chips, or the optional hard disk of the machine. Enter a 12-digit encoding code 
using the screen keyboard. The default encoding code is “111111111111”. When the 
setting is changed, the machine needs to be switched off and then on to make it 
effective. Note that all data corresponding to the encoding then will be initialized.
NOTE: Encrypted data cannot be recovered if a problem occurs in the hard disk.
Software Download
Specify whether the machine is to allow software downloads.
Country
Specify the country code for the line type used in your area.
NOTE: When setting up Fax options, users in European countries and North 
American countries may be required to set the country code for the line. Specify the 
country referring to the chapter on Other Settings.  Also refer to Country Code for Fax 
Option on page 343.
