Secure disk erase
The printer's hard disk is used as a temporary storage area for print jobs. The Secure Disk Erase facility
can completely erase your information from the hard disk to protect it from unauthorized access. You can
choose to erase particular files, or the whole hard disk.
Secure Disk Erase provides three different levels of security:
●
Non-Secure Fast Erase: 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: 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 Fast Erase, 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: 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 Disk Erase.
Secure Disk Erase is one of the facilities provided by Web JetAdmin, which is HP's free Web-based print
management software.
If you have difficulty in using Secure Disk Erase from Web JetAdmin, please contact HP Support. See

NOTE:
If you choose to erase the whole hard disk, you may be asked to restart the printer several
times during the process, which will take about 6 hours with Secure Disk Erase or 24 hours with
Secure Sanitizing Erase.
