● Using a USB flash drive. Download the firmware file from http://www.hp.com/go/pagewidexlseries/ support/firmware/ (according to your printer model) into the USB flash drive and insert it into the HiSpeed USB host port in the front panel. A firmware update assistant will appear on the front panel to guide you through the update process. Secure File Erase The printer's hard disk is used as a temporary storage area for print jobs. Secure File Erase can erase your temporary files from the hard disk to protect them from unauthorized access. It begins to do so as soon as you turn it on, but old temporary files that were already on the hard disk are not erased retroactively. If you want to erase the old files too, see Disk Wipe on page 118. Secure File Erase provides three different levels of security: ● Non-Secure: all pointers to the information are erased. The information itself remains on the hard disk until the disk space it occupies is needed for other purposes, and it is then overwritten. While it remains on the disk, it is difficult for most people to access, but may be accessed using software designed for the purpose. This is the normal method in which files are erased on most computer systems; it is the fastest method but the least secure. ● Secure Fast Erase (1 pass): all pointers to the information are erased, and the information itself is also overwritten with a fixed character pattern. This method is slower than Non-Secure, but more secure. It may still be possible to access fragments of the erased information by using special tools to detect residual magnetic traces. ● Secure Sanitizing Erase (5 passes): all pointers to the information are erased, and the information itself is repetitively overwritten using an algorithm designed to eliminate any residual traces. This is the slowest method, but the most secure. Secure Sanitizing Erase meets the US Department of Defense 5220-22.m requirements for clearing and sanitization of disk media. This is the default security level when using Secure File Erase. While files are being erased, the printer's performance may be affected. Secure File Erase is one of the facilities provided by Web JetAdmin, which is HP's free Web-based print management software: see http://www.hp.com/go/webjetadmin. If you have difficulty in using Secure File Erase from Web JetAdmin, contact your support representative: see When you need help on page 121. The Secure File Erase configuration can be changed from Web JetAdmin or the Embedded Web Server (Setup > Security). Disk Wipe Disk Wipe is the same as Secure File Erase (see Secure File Erase on page 118), except that it erases all temporary files, including old ones. 118 Chapter 9 Maintenance ENWW

Secure File Erase
The printer's hard disk is used as a temporary storage area for print jobs. Secure File Erase can erase your
temporary
files
from the hard disk to protect them from unauthorized access. It begins to do so as soon as
you turn it on, but old temporary
files
that were already on the hard disk are not erased retroactively. If you
want to erase the old
files
too, see
Disk Wipe
on page
118
.
Secure File Erase provides three
different
levels of security:
●
Non-Secure:
all pointers to the information are erased. The information itself remains on the hard disk
until the disk space it occupies is needed for other purposes, and it is then overwritten. While it remains
on the disk, it is
difficult
for most people to access, but may be accessed using software designed for the
purpose. This is the normal method in which
files
are erased on most computer systems; it is the fastest
method but the least secure.
●
Secure Fast Erase (1 pass):
all pointers to the information are erased, and the information itself is also
overwritten with a
fixed
character pattern. This method is slower than Non-Secure, but more secure. It
may still be possible to access fragments of the erased information by using special tools to detect
residual magnetic traces.
●

all pointers to the information are erased, and the information itself
is repetitively overwritten using an algorithm designed to eliminate any residual traces. This is the
slowest method, but the most secure. Secure Sanitizing Erase meets the US Department of Defense
5220-22.m requirements for clearing and sanitization of disk media. This is the default security level
when using Secure File Erase.
While
files
are being erased, the printer's performance may be
affected.

The Secure File Erase
configuration
can be changed from Web JetAdmin or the Embedded Web Server (

).
Disk Wipe
Disk Wipe is the same as Secure File Erase (see

), except that it erases all
temporary
files,
