Securing the Hard Drive
This section includes:
Selecting the Hard Drive Overwrite Security Option
When a file is deleted from the printer’s hard drive, only the file name is deleted; the data in 
the file remains on the hard drive, regardless of the operating system. An unauthorized person 
could retrieve the data in the file that was deleted. 
Printers with a hard drive have a Hard Drive Overwrite Security option. This option overwrites 
the data stored on the hard drive of a file marked for deletion using DOD5200.28-M, a U.S. 
Department of Defense three-pass overwriting process: first with a pattern of 0’s, next with a 
pattern of 1’s, and finally with a random pattern of bits. This is done before the file’s directory 
entry is removed and the storage space on the hard drive is marked as available for reuse. The 
random pattern of bits stays on the hard drive until it is overwritten by another file. 
By default, the Hard Drive Overwrite Security option is disabled. To select the Hard Drive 
Overwrite Security option, use one of the following methods:
The printer’s control panel.
