III. Secure Sanitizing Erase: In this mode of operation, file pointers are erased and the disk space
where the temporary job was stored is repeatedly overwritten using an algorithm that prevents any
residual data. This mode of operation may affect product performance. The Secure Sanitizing
Erase mode of operation meets the US Department of Defense 5220-22.m requirements for clearing
and sanitization of disk media. When the Secure Sanitizing Erase feature is enabled, all
temporary files that may contain sensitive data are erased with this method--- no temporary files are
left after a job has completed (scan, copy, or print).
Furthermore, in case you do not want to store jobs in the printer, you can set to 0 the number of jobs to be
stored in the printer’s queue. To enable this, go to the printer’s front panel; “setup” menu and then go to
“job management setup.” For further information, please refer to your printer’s user manual.
2. Secure Disk Erase
There is also the option to delete the complete disk in either of the two secure methods described above,
(Secure Fast Erase and Secure Sanitizing Erase) this will sanitize the whole disk in one go by removing any
user data in a secure manner so the device can be moved out from a secure area to an insecure area.
This setting can only be done via Web JetAdmin or the Front Panel “Service menu” by an HP authorized
engineer or by contacting HP Support directly with a request to access.
All disk erasing will be done via the same level of security erase. The Secure Disk Erase feature is already
implemented for these printers:
o HP Designjet Z3100/Z3200
o HP Designjet Z6100
o HP Designjet T1100
o HP Designjet T1120
o HP Designjet T770 HDD
o HP Designjet T1200 / T1200 PostScript
o HP Designjet 4000/4500 printers
o HP Designjet 4020/4520
3. User Interface
Shown here is how to set these options using two different user interfaces: HP Web Jetadmin and the
printers Front Panel “Service Menu”
• HP Web Jet Admin access: When the interface used to manage Secure File Erase and Secure Disk
Erase functionality is HP Web JetAdmin, we can use the same SFE/SDE functionality that is used in
the WJA device plug-ins for LaserJet printers, this means that you can set the same global options
across your fleet of HP LaserJet’s and HP Designjets. The example below shows the T1100ps being
configured using WJA:
