This section includes:

• Selecting the Hard Drive Overwrite Security Option

• Selecting the Automatic Removal of Secure, Personal, and Proof Jobs Option

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,

possibly, 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 0s (zeros), next with

a pattern of 1s, 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 control panel

•EWS

Using the Control Panel

To select the automatic removal of secure, personal, and proof print files from the hard drive:

1. On the control panel, select Printer Setup, then press the OK button.

2. Select File Security, then press the OK button.

Note: If File Security is locked on the control panel, use the EWS to select the Hard Drive

Overwrite Security option.

3. To remove all secure, personal, and proof print job files, select Overwrite Removals, then

press the OK button to select On or Off.

Note: The option Remove Job Files does not remove saved or protected print job files.
